A feller buncher is a type of harvester used in logging. It is a motorized vehicle with an attachment that can rapidly gather and cut a tree before felling it.

Feller is a traditional name for someone who cuts down trees, and bunching is the skidding and assembly of two or more trees. A feller buncher performs both of these harvesting functions and consists of a standard heavy equipment base with a tree-grabbing device furnished with a chain-saw, circular saw or a shear—a pinching device designed to cut small trees off at the base. The machine then places the cut tree on a stack suitable for a skidder, forwarder, or yarder for transport to further processing such as delimbing, bucking, loading, or chipping.

Some wheeled feller bunchers lack an articulated arm, and must drive close to a tree to grasp it.

In cut-to-length logging a harvester performs the tasks of a feller buncher and additionally does delimbing and bucking.

Components and Felling attachment

Feller buncher is either tracked or wheeled and has self-levelling cabin and matches with different felling heads. For steep terrain, tracked feller buncher is being used because it provides high level of traction to the steep slope and also has high level of stability. For flat terrain, wheeled feller buncher is more efficient compared to tracked feller buncher. It is common that levelling cabins are matched with both wheeled and tracked feller buncher for steep terrain as it provides operator comfort and helps keeping the standard of tree felling production. The size and type of trees determine which type of felling heads being used.

Types of felling heads

Disc Saw Head – It can provide a high speed of removal when the head is pushed against the tree. Then, the clamp arms will hold the tree when the tree is almost completed removal. It is able to cut and gather multiple trees in the felling head. The disc saw head with good ground speed could provide high production which allows it to keep more than one skidders working continuously.
Shear Blade Head – It is placed against the tree and the clamp arms will hold the tree firmly. Then, the blade will activate and start removal the tree. Same as disc saw head, it can hold multiple trees before they are placed on the ground.
Chain Saw Head – The floppy head provides minimal control to place the trees on the ground. It might not suit to collect the cut trees or gather the cut stems in the felling head.

Benefits of Tree removal

Whenever people talk about tree removal, usually the things that spring to mind are negative thoughts brought on mostly by media hypes and environmentalist drives. People think about global warming, depletion of natural resources, and the casual extinction of indigenous fauna and flora. Yet people don’t seem to realize that there are actually quite a few benefits of tree removal.

One of the easiest benefits of tree removal to spot are the economic ones. Lumber products are one of the most staple constructive materials in human society. Whether it’s raw lumber used for making tables and houses, or paper and other wood by-products, we simply cannot live without the use of lumber. Like steel and stone, wood is one of the most basic natural resources, and unlike steel and stone, it is renewable simply by growing more trees. The only real trick to balancing it’s consumption is to grow more trees to replace the ones taken.

On a similarly related note, keep in mind that a lot of jobs revolve around the use of lumber. Wood cutters aside, there are those who work in processing plants to make glue from wood sap, process pulp into paper, and others. This is another benefit of tree removal; it opens more job opportunities for people who would otherwise be unemployed. These job opportunities are more than simply a humanitarian concept; society at large would suffer if all of the people working in the wood industry were to suddenly find themselves jobless.

This benefit of tree removal not only covers the people who cut down trees and process them, but also extends to the people who “clean up” after them. For every patch of forest cut down, arable land becomes available for farmers, or can be used as an area to place urban living sites like apartments, houses, and buildings. The number of people employed by such a construction project are many and varied. Or, if the city/government mandates replanting trees to replace the lost ones, then jobs are also provided for those people who do the seeding after a patch of forest is stripped.

Thinking about it, the cleared areas are places which provide a lot of potential for growth, and this is yet another benefit of tree removal. As stated above, arable land is valuable, and the act of tree removal to clear a place for farm land provides a much needed additional food source for man. More often than not, the soil in a forest is much richer than that of regular farm lands because of the wide variety of life it supports. This new land area grants a much needed place to grow a food supply to deal with the planet’s steadily expanding population of humanity.

Then, of course, there is the fact that these cleared areas may be razed for urban renewal. Given our burgeoning population growth, additional living areas made on cleared forest land is another benefit of tree removal. These places can be converted into more than just housing areas. Buildings which can house offices for work, or factories to produce clothing and other essential items, or even research facilities for things like new medical or technological advances can be placed in these deforested areas.

Lastly, another benefit of tree removal to consider is the access it provides to other natural resources that may lay within the forest’s land area. Some places with heavy forests are home to iron ore, mineral, and even oil deposits which can be used for man’s needs. These natural resources would otherwise lay dormant and untapped unless people access them. The act of tree removal may not be entirely necessary to get at these deposits sometimes, but coupled with the advantages given above, the combination of opening up a new mine or oil well when taken with extra living spaces or farm lands for food makes a lot of sense.

So, given all of the benefits of tree removal outlined above, you can see that more often than not, the good outweighs the bad. The planet’s environment may indeed suffer from the effects of tree removal, but that is due to irresponsible use of the resources and other benefits provided, not the tree removal itself. As people living on the planet, our duty is not to “hold back” and stop removal trees. It is to use what we glean from the Earth responsibly and wisely for humanity and the planet’s benefit.

When is the Best Time of Year for Tree Removal?

Cheapest time to cut down a tree urban forest pro best time for tree removal We get asked often ‘what is the cheapest time of year to have a tree cut down?’ The cost of removing a tree in Roosevelt Utah can vary based on many things. And one of the main factors is the time of year in which the tree is removed. There truly is the best time of year to cut down trees.
The short answer: tree removal typically costs much less during the winter or spring months, making it the best time for removal. Below we’ll explain why winter or early spring is the cheapest time of year for tree removal, as well as other things to watch out for and consider as you seek estimates from top arborists near you.

Costs For Removal Down A Tree Can Vary On A Company’s Workload

Supply and demand often plays a big role for many leading nearby tree Service Company’s pricing. The need for tree removal is typically lower during winter and spring, so the best tree companies may offer lower rates to ensure steady business. Here at Urban Forest Pro, we offer more competitive rates during the winter months because many people aren’t thinking about their trees during these colder months. This can mean a decent savings for a homeowner looking for the best time to remove a tree from their property from a price perspective.

Why is Winter The Best Time For Tree Removal?

There are a number of reasons why later winter or early spring are considered the best time of year to hire a tree service near you for your tree removal project. February and March are statistically the cheaper months for tree removal—as they are otherwise known as “dormant season” for trees. During the winter the leaves have fallen from the trees making it easier for a tree service to cut down the tree safely and quickly.

Removal a tree down during these months is also advantageous and considered the best time of year for the environment. The colder ground means the surrounding earth is less impacted while a top Roosevelt Utah tree service handles the tree removal. Frozen ground can keep the nearby vegetation in place while the tree is being cut down during the extraction as well.

On the other hand, top tree companies can get super busy during late spring and summer; i.e., the stormy or windy months. This is when places may need emergency tree services and removals which will also impact the pricing for a tree to be cut down.

Most reputable tree companies who have tree experts working for them in Roosevelt Utah have licenses and modern equipment to maintain; so, if rates are suspiciously and noticeably low for tree removals, we advise caution: it could mean the company is skipping costs in an important area so that they can offer the best price for removal down a tree. But the lowest cost is not always the best cost no matter what time of year it is.

Even if winter is the best time to cut down a tree on your property from a price point of view, despite “busy” or “dormant” seasons, you can get a tree removed at any time of the year. It just may impact the cost.

If you do have trees that need removal, the top certified arborists here at Urban Forest Pro can offer not only competitive rates but also an unparalleled level of professional, safe, and efficient work.

WHAT IS TREE REMOVAL?

When providing a proposal for a tree removal, an arborists also evaluate the site for tree REMOVAL. While having the tree ground is not always necessary, many people prefer to deal with the tree at the same time as having the tree removed. Tree removal allows the property owner to use the area where the tree once stood for laying sod or planting a flower bed. The tree grinder also produces mulch that has many uses around the yard. Here are answers to some common questions we get about tree removal.

HOW DEEP CAN THE TREE GRINDER GO?

They generally grind four to six inches below grade (ground level). If deeper removal is needed, it can be requested, although the price of tree removal may increase. The depth to which a tree can be ground is subject to some limitations, however. The tree-removal blade has a diameter of about 10 inches, and can only be maneuvered up and down within a specific range.

A tree that grew in shallow soil, such as over the limestone bedrock prevalent in the Cedar hills area, may not have six inches of grindable depth.

Other material near or around the tree may limit how deep the grinder can go. While the tree grinder is powerful, it is only designed to handle plant material, wood, and dirt. Take note of:

Fencing, concrete, brick, or rock around a tree (such as a tree ring)

Nearby trees that may have roots under the tree

Swimming pools, walkways, and patios that may prevent the grinder from reaching all of the root material

Lawn irrigation, sprinkler systems, tree lighting wiring, and buried hoses

We generally do not grind deep enough to risk interfering with properly-installed utility lines or buried cables, but unforeseen obstacles can be encountered that necessitate a shallower grind.

What exactly lies beneath the roots of a tree or the surrounding soil may be a mystery, even to the homeowner. While we are very careful when removal a tree, we will not take responsible for damage to irrigation lines or other items located below ground that we are not aware of. It is important to inform your arborist of any sprinkler systems or other objects that might be in the area to be ground before the work begins.

WHAT IS LEFT AFTER A TREE IS GROUND?

As the blade grinds the tree and surface roots, it produces a mulch made up of tree material and dirt. The mulch produced by tree removal can take up a much greater volume than the original tree. (It can be helpful to think of the difference between a block of cheese and that same cheese after it is grated.)
Mulch from tree removal is valuable organic material that decomposes more quickly than many other kinds of mulch, as there are generally smaller wood particles present, and more soil to help it break down. It is our standard practice to push the mulch back into the area that has been ground (“backfilling”). Even so, there is usually a large pile of mulch left above ground, often much more than the tree owner expected. Because of its composition, the mulch does settle fairly quickly, but many people prefer to use the mulch around their yards, rather than leaving it where the tree once was.
Tree grinder mulch can be used for composting or applied in flower beds. (Depending on exact composition of the mulch, it may not perform in the same way as typical hardwood mulch, and may need to be replaced sooner.) After some time, when the mulch has settled, it can be packed into the ground-out area, making the area ready to be prepped for laying sod or for planting a flower bed or other small plants. If requested, we can provide mulch bagging and/or bagged mulch haul-off as an additional service after tree removal, but our standard practice is to leave all grinder mulch on-site.

WILL THE TREE COME BACK AFTER A TREE IS GROUND?

Even with tree removal, some species of tree can still send up shoots and new growth from the roots left below ground. Crape myrtles, chinaberry trees, hackberries, and Bradford pears are some common species in the area that can be very persistent in growing back. The sprouts that return after tree removal can be trimmed or mown down and will eventually stop coming back, as the remaining roots use up their energy reserves. Commercially-available woody stem killer can be used to accelerate the dieback of the roots. White vinegar can also be used as an organic alternative to commercial root killer.

CAN I REPLANT AFTER A TREE IS GROUND?

We are often contacted about removing a tree that the owner would like to replace. We do not recommend trying to re-plant trees in the same area where a tree was removed and the tree ground. Even with a deep grind, an extensive root system remains underground.

The old root system can interfere with the new tree’s attempts to become established. Furthermore, if the old tree had a disease, that disease may still be present in the remaining root tissue, and can be transmitted to the new tree. When replanting is desired, we can discuss finding a location that is far enough from the removed tree to lessen the likelihood of interference from the old root system. If homeowners’ association or municipal restrictions require a tree to be replaced in a certain location, excavation or hand digging may be the only options.

CAN EVERY TREE BE GROUND?

In the case of a tree becoming uprooted (because of storm damage or root rot, for example), the tree cannot be dealt with as easily. If there is a large amount of root material above ground, the tree grinder may be physically unable to reach it. Depending on the type of tree and how it grew, it may pull up a great deal of dirt, turf grass, and other underground material when it falls. What is left after removal an uprooted tree may be more dirt than tree matter, and may not be suitable for use as mulch.

Weather is also a factor that can determine how and when tree removal can be performed. A long period of rain can cause the soil to become waterlogged. Operating a tree grinder in heavy, wet soil can not only make a bigger mess than usual, but can damage the surrounding area due to the weight of the machine. It may be necessary to wait until the area dries out before attempting even a “standard” tree grind.

If a customer has a special circumstance, like an uprooted tree, or there are multiple trees in one area to be ground, we always send an arborist to assess the situation before providing a quote or scheduling the tree grinder.

HOW MUCH DOES TREE REMOVAL COST?

The cost of tree removal is dependent upon three main factors: the size of the tree, the location of the tree, and how deep the grinder needs to go. While we generally provide a tree removal price when we give a quote for tree removal, we are also happy to evaluate any other trees you may want to have ground.

HOW DO I MEASURE A TREE?

The base cost for tree removal is determined by the diameter of the tree in inches, including any above-ground roots. This measurement can be taken before or after a tree is removed. To get the right measurement, it is important to go “from dirt to dirt.” This means measuring from the tree edge or root point (where it touches the dirt) farthest from the trunk to the opposite edge or root point. It is also important to measure from different directions and to take an average measurement, as this most accurately reflects the area to be ground. The “dirt-to-dirt” measurement can be quite a bit larger than the diameter of the tree trunk, and we do see situations where the tree removal is more costly than removing the above-ground tree.

This is a 75-inch tree, measured “dirt to dirt” at the yellow line. Measuring on the trunk is inaccurate: if this tree were measured at the red line, the result would only be 37 inches, which is not the actual area to be ground. Even after a tree is cut down, properly measuring a tree can be tricky when there is a root flare and surrounding vegetation.

CAN THE TREE GRINDER REACH MY TREE?

Our standard tree grinder is a machine that is seven feet long and three feet wide. At the front is a rounded blade (similar to the tip of a chainsaw) that chips away wood as it moves across the tree. The tree grinder is designed to fit through standard gates, but some older or narrow gates may not be able to accommodate it. The weight of the machine may also prevent it from reaching certain areas without damaging walkways or ground cover. While the removal blade has some maneuverability, clearance of at least seven feet on one side of the tree is required to allow the grinder to access the area to be ground. In smaller areas with less clearance, it is possible to use our smaller tree grinder, but this can increase the time and cost of the procedure.

CAN I JUST LEAVE THE TREE?

It is not necessary to grind or otherwise remove a tree after a tree is taken down. We have customers who request a tree not be cut all the way to ground level, and use the remaining tree as a plant stand, table base, or just a yard feature. Even if the tree is cut close to the ground, it can last several years. Preservative coatings can also be applied to prolong the life of a standing tree.

Some homeowners prefer to let a tree decompose naturally over time. Old trees can become habitats for fungi, insects, and other creatures. As the tree breaks down, it can become rich organic material that can be added to compost or used in planting. If a tree is left unground, however, it can continue to send out new growth for years after the tree has been removed. Drilling holes in the tree and filling with Epsom salt or using commercial tree killer can accelerate tree dieback, but those chemicals can be toxic to surrounding plant life. Treating the tree with chemicals can also make the area hazardous to people and pets.

Tree Felling

Arborist Near Me

Tree Felling

Felling is the process of cutting down trees, an element of the task of logging. The person cutting the trees is a feller. A feller buncher is a machine capable of felling a single large tree or grouping and felling several small ones simultaneously.
Methods

Hand felling

In hand felling, an axe, saw, or chainsaw is used to fell a tree, followed up by limbing and bucking in traditional applications. In the modern commercial logging industry, felling is typically followed by limbing and skidding.

Feller buncher

A feller-buncher is a motorized vehicle with an attachment which rapidly cuts and gathers several trees in the process of felling them.

In cut-to-length logging a harvester performs the tasks of a feller-buncher, additionally doing the delimbing and bucking. When harvesting wood from a felled tree, the recommended methods should be followed in order to maximize wood recovery. The suggested trend is to make deeper cuts and smaller openness when performing undercuts.

Types of cut

The undercut or notch cut is the guiding or aiming slot for the tree and is a V-shaped notch placed on the side of the tree in the direction of intended fall.

The back cut or felling cut is made on the opposite side of the tree of the undercut and is cut through the base of the tree severing the “hinge” holding the tree up.

Boom-corridor experiment

This was an experiment conducted regarding felling trees and the continuous felling of trees in boom-corridors which might lead to an increase in harvester productivity. An efficient way to do this would be to use felling heads which would increase efficiency and fall time.

A feller buncher is a type of harvester used in logging. It is a motorized vehicle with an attachment that can rapidly gather and cut a tree before felling it.

Feller is a traditional name for someone who cuts down trees, and bunching is the skidding and assembly of two or more trees. A feller buncher performs both of these harvesting functions and consists of a standard heavy equipment base with a tree-grabbing device furnished with a chain-saw, circular saw or a shear—a pinching device designed to cut small trees off at the base. The machine then places the cut tree on a stack suitable for a skidder, forwarder, or yarder for transport to further processing such as delimbing, bucking, loading, or chipping.

Some wheeled feller bunchers lack an articulated arm, and must drive close to a tree to grasp it.
In cut-to-length logging a harvester performs the tasks of a feller buncher and additionally does delimbing and bucking.

Components and Felling attachment

Feller buncher is either tracked or wheeled and has self-levelling cabin and matches with different felling heads. For steep terrain, tracked feller buncher is being used because it provides high level of traction to the steep slope and also has high level of stability. For flat terrain, wheeled feller buncher is more efficient compared to tracked feller buncher. It is common that levelling cabins are matched with both wheeled and tracked feller buncher for steep terrain as it provides operator comfort and helps keeping the standard of tree felling production. The size and type of trees determine which type of felling heads being used.

Types of felling heads

Disc Saw Head – It can provide a high speed of cutting when the head is pushed against the tree. Then, the clamp arms will hold the tree when the tree is almost completed cutting. It is able to cut and gather multiple trees in the felling head. The disc saw head with good ground speed could provide high production which allows it to keep more than one skidders working continuously.
Shear Blade Head – It is placed against the tree and the clamp arms will hold the tree firmly. Then, the blade will activate and start cutting the tree. Same as disc saw head, it can hold multiple trees before they are placed on the ground.

Chain Saw Head – The floppy head provides minimal control to place the trees on the ground. It might not suit to collect the cut trees or gather the cut stems in the felling head.

Productivity

Comparing other harvesting systems such as chainsaw and harvester, feller buncher has the relatively high productivity among them. The weekly production of the feller buncher was 627 cubic meters of usable logs, while the chainsaw system and harvester system could produce 163 cubic meters and 239 cubic meters respectively. There are several factors affecting the level of productivity of the feller buncher. They include characteristics of stand, terrain conditions, operation location, and the performance of the operator. Many studies indicated that the trees size and the gradient of the slope are the major factors impacting the overall productivity. There was a research suggested that productivity has a significant positive relationship with the tree size which means the larger stem size, larger tree height or larger diameter at breast height (DBH) results in a high productivity of the feller buncher. Terrain conditions such as ground slope and terrain roughness have a significant negative relationship to the productivity of feller buncher which means the steeper of the land or rough terrain condition can bring negative effect to the productivity. One of the studies had found that feller buncher might reduce its productivity when performing operation on a very uneven surface with slopes of more than 20%. However, larger tree size does not necessarily lead to high productivity. The same study compared the operation time when performing clear-cut of the stands with two different average DBH, 24.6 cm and 34.3 cm respectively. Result showed that the productivity when operating the second stand decreased by 32.3% because the time consumption was doubled when larger stands required two-stage of cutting operation.

Cost-effectiveness

A forwarder hauls stacked logs left behind by a feller buncher.

The purchase cost of a feller buncher is around $180,000 and its fuel consumption and lubricant consumption is high among other mechanical harvesting equipment. The feller buncher also has the highest hourly cost which is around $99.5 when comparing other equipment such as a harvesters and grapple skidders. Although the total cost of feller buncher is high in overall, the unit production price is the lowest which explains why feller buncher is considered the most cost-effective harvesting equipment. The average unit cost of the feller buncher is $12.1/m3 while the unit cost of the harvesters is $16.5/m3. The unit cost of the feller buncher is primary affected by the tree size and the tree volume. The unit felling cost is lower when the tree size increased. For example, tree with 5 inches at DBH has the unit cost of $70 while tree with 15 inches at DBH has the unit cost of $12. As the cost of feller buncher is high, only large tree volume can produce more profit to cover the high average cost. In terms of stump height, lower stump height can maximise the use of natural resources and prevent wood waste. Mechanical felling such as using feller buncher can prevent 30% of value loss caused by the high stumps.

Maintenance

Feller buncher requires daily maintenance before operation and some components only require periodic maintenance. It could ensure the safety of operators and all the workers around the operation. If damaged or faulty machine is operated, it could result in further damage to the machine which can be more expensive to repair.

Daily or Every 8 hours

Lubrication

The felling head is considered one of the hardest part of the feller buncher and it is necessary to apply lubricant to every joint for daily maintenance. It is suggested to apply lubricant to saw head clamps, wrist attachment and driveshaft bearings during every maintenance. The use of grease should meet the extreme pressure performance standard and contains 3% of molybdenum disulphide (MoS2). MoS2 can prevent the wear takes place where the metal to metal contact exists.

Fuel

It is also important to check if there is enough fuel for the operation. Feller bunchers use diesel fuel to generate power. In most of the cases, the fuel is preferably to have cetane number greater than 50 (minimum 40). This is suitable when undergo operation for temperature below -20 °C (-4 °F) or elevations more than 1500m (5000 Ft.). The Cloud Point of the fuel is preferably at least 5 °C (9 °F) lower than the expected low temperature. It is also suggested that the sulphur content of the fuel should not be more than 0.5% as it could reduce 50% of the service interval for the engine oil and filter.
Older style felling head that uses a bar and chain to cut trees instead of the more modern saw disk.

Engine coolant

Operators have the responsibility to check the engine coolant level of the feller buncher before starting the engine. The coolant prevents cylinder linear erosion and pitting, and provides protection during extremely low temperature for up to -37 °C (-34 °F).

It is recommended to use coolants for heavy-duty engines which are relatively low silicate ethylene glycol base. There are two forms of coolants: pre-diluted or concentrate. Water is required to dilute the concentrated coolant with an approximate ratio of 50:50. The use of supplemental coolant addictive might be also required in the concentrated coolant in order to provide protection against corrosion. Distilled, deionised, or demineralised water is suggested for mixing the concentrated coolant because when some water compositions mix with other substances could form a precipitate, causing damage or blockage in the engine.

Risk management approach

During maintenance, there are common working hazards related to two main areas: working environment and exhaust system. When working on the exhaust system, be aware of the hot components around the engine. Workers could wear personal protective equipment such as safety spectacles, heat-proof gloves and safety boots. When feller buncher is elevated for service or maintenance, falls from height might happen. Related injuries could be avoided by ensuring dryness of all the walking surface, wiping any oils or other liquid substances on the floor. Also, ensure the feller buncher is parked on a level and stable ground during maintenance.

When getting in and out of the machinery, workers are suggested to use three point of contact with two hands holding the handrails and one foot on a step. It is also important to provide sufficient lighting for all the working sites at all time of service.

Safety

Logging is considered one of the most dangerous occupations. This is because many loggers are injured by the falling objects which are large in size and heavy. “Struck by object” is the most common injuries that reported in the logging industry due to the manual use of equipment during the logging procedures. There is evidence that using mechanized harvesting equipment could reduce the rate of “struck by” injuries. One study indicates that total injury claims could be reduced by 14.2%, while the “struck by” injuries could be reduced by 8.2%, when comparing the changes before and after the use of feller buncher. The significant decline in the number of “struck by” injuries after using the feller buncher in the logging companies supported the statement that using mechanized harvesting equipment could lessen overall injuries. The evidence also found that the rate of injuries in the logging companies without using feller bunchers had increased slightly throughout a period of time, increasing from 14.5% to 17.5%, in five years. In terms of trees fatality, areas with lower levels of mechanization in harvesting resulted in higher rate of trees fatality. For instance, in Eastern areas of the United States, research which compared the conventional and mechanized logging operations, indicated the number of injuries, when using the conventional approach, is three times greater than that of using the mechanized equipment such as a feller buncher. However, mechanized related injury could be raised accordingly, especially when performing machine maintenance or repair. These kinds of injuries could be serious and also costly.

Limitations

Feller buncher could be highly productive and cost-effective but there are several limitations. Feller buncher is less beneficial when performing operations on a very rough and relatively steep land. For example, in Appalachian hardwood area, trees have heavy crowns and are grown on the steep slopes which requires tracked feller bunchers in the operations. Although tracked feller bunchers allow operations on a steep slope, the cost-effectiveness is not well studied. Also, manual felling can operate on the steeper slopes than the feller bunchers do. On the other hand, feller bunchers are cost-effective only when there is a high volume of trees in the operations. If there is not enough timber to harvest, the unit cost can be expansive, especially when the majority of the operation site is steep slopes. A 2013, University of Maine study suggests that the use of feller bunchers could cause medium to high level of stand damage from 7% to 25%. However, in comparison with other equipment such as harvesters, the damage that caused by the feller bunchers are less severe.
