Labels

Your DR TreeChopper carries prominent labels as reminders for its proper and safe use. Shown below are copies of all the Safety and Information labels that appear on the equipment. Take a moment to study them and make a note of their location on your TreeChopper as you set up and before you operate the unit. Replace damaged or missing safety and information labels immediately.

Operating this TreeChopper safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe operation can create a number of hazards for you as well as anyone else in the nearby area. Always take the following precautions when operating this TreeChopper:

 Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and

themselves.

 Read the ATV operators manual, the Winch operators manual and all warning labels before operating.  Prior to use remove the blade guard and ensure that the blades are properly adjusted as outlined in your TreeChopper’s

operation manual.

 Stay clear of all moving parts or joints that may be a potential pinch point hazard.  Never allow bystanders to stand, or ride on the chassis or the head assembly of the TreeChopper.  Always reinstall the blade guard after use and prior to transport.  Never operate the TreeChopper without the tree guard properly affixed and adjusted per the instructions outlined in your

operators manual.

 Never attempt to cut trees larger than 4" in diameter.  Never operate the TreeChopper without the extension arms installed.  Never equip a TreeChopper to an ATV that is less than 400cc and always operate the ATV in four wheel drive.  Inspect all hardware, mounting brackets, blades and guards for loose, bent, broken or failing components prior to operation.

If any component is damaged, or missing, replace it immediately prior to operation.

 Always follow all warnings outlined in your ATV’s operation manual and on the machines warning labels.  Never exceed 15 mph (24 kph) even with the TreeChopper in the raised transport position.  Keep bystanders at least 100 feet away from your intended work area and always be aware of their location.  Never attempt to cut a tree larger than 4" in diameter. The TreeChopper is designed to only cut trees. Do not attempt to cut

wooden fence posts, rebar, or any object other than a 4" diameter or smaller tree.

 Always wear an approved motorcycle helmet that fits properly and is equipped with a face shield in conjunction with

protective goggles to protect your eyes and face from stray branches or debris.

 Avoid wearing loose clothing or jewelry, which can catch on moving parts.  We recommend wearing gloves while using the TreeChopper. Be sure your gloves fit properly and do not have loose cuffs or

drawstrings.

 Wear shoes with non-slip treads when using your TreeChopper. If you have safety shoes, we recommend wearing them.

Never work on or use the TreeChopper barefoot or while wearing open toed shoes/sandals (footwear).

 Wear a long sleeve shirt or riding jacket and long pants while operating the TreeChopper.

Protective Gear

Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the machine and the chopping activity.

Never

assume that children will remain where you last saw them. Always follow these

precautions:

 Never operate the TreeChopper with children or pets present. Keep children and pets at least 100 feet from the working area

and ensure they are under the watchful care of a responsible adult.

 Be alert and put the ATV in “Park”, set the parking brake, turn the ATV off, lower the TreeChopper and install the guard if

children or pets enter the work area.

 Never allow children under the age of 16 to operate the TreeChopper.

Safety for Children and Pets

Protecting yourself and those around you

4 DR

TreeChopper™

Protecting yourself and those around you (continued)

 Never cut trees near power lines, gas lines, or any other obstacle that may pose a fire, explosion, or electrical hazard. Never

assume a tree will fall where you intend it to.

 Always stop the ATV, place the transmission in park (when applicable) set the parking brake, replace the blade guard and

lower the TreeChopper to the ground prior to allowing another person or pet to approach.

 Never allow passengers to ride on the ATV while the TreeChopper is installed on the machine, even if the ATV is designed to

safely transport passengers.

 Prior to chopping trees inspect the area you will be intending to cut in for any debris or objects that may pose a hazard.

Inspect all trees prior to chopping them by following the practices outlined in the TreeChopper operation manual.

 Never attempt to cut a tree without first surveying the tree for branches that may cause an impalement hazard. Remove all

branches that pose such hazards prior to cutting. Failure to do so can cause serious injury or even death.

 Always inspect the tree(s) you are intending to cut for ingrown hazards such as rocks, metal rebar, or fencing. Never attempt

to cut a tree that has an ingrown object.

 Do not operate the ATV on slopes greater than 10° with the TreeChopper installed.  Always begin cutting on small diameter trees that are in the early stages of growth to learn the characteristics and techniques

of the TreeChopper equipped to your atv

 Never operate the atv with one hand while the TreeChopper is mounted  Always approach all ravines, pot holes and ditches at a slow speed and head on to prevent rollover. Avoid all obstacles and

never attempt to chop a tree that lies near or in a ravine, ditch or other hazardous terrain feature.

 Do not operate your TreeChopper with material wedged in the blades. Safely remove any stuck or jammed material prior to

using your TreeChopper. Once material is removed, inspect your TreeChopper Blades for damage, alignment, and spacing.

 Never stand or ride on the TreeChopper head or chassis – never allow passengers or bystanders to do so either.  Always reinstall the blade guard after use and prior to transport. The blade guard should only be removed prior to cutting

trees and should be promptly reinstalled after use.

 Never operate the TreeChopper without first inspecting all hardware connections for bent bolts, missing hardware, or

loosened components. Tighten or replace before use with DR components.

 Learn to properly operate your ATV prior to using your TreeChopper.  Prior to and after use, always check the condition of the cutting blades. Sharpen or replace any damaged blade per the

instructions found in your operators manual.

 When readying to cut a tree make sure you are firmly seated on the ATV. Never attempt to cut a tree in a slightly raised or

standing position.

 Your TreeChopper is a powerful tool, not a plaything. Exercise extreme caution at all times. The machine is designed to chop

small trees. Do not use it for any other purpose.

 Always follow ATV warning and riding instructions in your ATV manual. Failure to read your ATV manual could result in

personal injury or equipment damage.

 Do not attempt to cut Trees with trunks larger than a 4 inch diameter.  Prior to use, check the TreeChopper to be sure all bolts are tight and the blades are properly adjusted. Floating head bolts

should be snug, but loose enough to allow the head to float and follow the contours of the ground.

 Approach trees to be cut from a safe distance, approximately 10 feet.  Approach tree at a safe speed and accelerate through the tree during cutting.  Know how to stop your ATV quickly; see your ATV owners Manual.  Never operate TreeChopper in slippery, wet, muddy, or icy conditions.  See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by DR

Power Equipment.

 Never use the machine without ensuring that all guards and shields are in place.  Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the TreeChopper. This

includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and will void your warranty.

Protecting yourself and those around you (continued)

 Allow only one person on the ATV to operate the TreeChopper at any time.  If the TreeChopper should start making an unusual noise or vibration, stop the ATV and put it in park, lower the TreeChopper

to the ground, turn the ATV ignition to the “Off” position, remove the key and set the emergency brake, then inspect for damage. Vibration is generally a warning of trouble. Check for damaged parts and clean, repair, and/or replace as necessary.

 Never tamper with safety devices. Check their proper operation regularly.  Before performing any maintenance or inspection procedure on the TreeChopper, stop the ATV and put it in park, lower the

TreeChopper to the ground, turn the ATV ignition to the “Off” position, remove the key and set the emergency brake.

 Never allow people who are unfamiliar with these instructions to use the TreeChopper. Allow only responsible individuals

who are familiar with these rules of safe operation to use your machine.

 Never overload or attempt to chop material beyond the manufacturer’s recommendation. Personal injury or damage to the

machine could result.

 While using the TreeChopper, don't hurry or take things for granted. When in doubt about the equipment or your

surroundings, stop the machine and take the time to look things over.

 Never operate the machine when under the influence of alcohol, drugs, or medication.  Use the machine only in daylight.  Stay alert for hidden hazards or traffic.  Keep all nuts and bolts tight and keep the equipment in good operating condition.

Installation Notes

 The universal mounting plate has been designed to easily attach to most ATV frames.  The mounting bracket attaches to the frame of your ATV which must not be dented, bent, collapsed or rusted. Secure mounting

is necessary for safe and successful use of the TreeChopper.

 The TreeChopper should only be installed on ATVs that are 400cc or more and have 4-wheel drive.  Always keep all guards and shields in place when the TreeChopper is not in use. This includes during assembly and while

attaching or detaching the TreeChopper to your ATV.

 Proper installation of the mounting bracket onto the frame of your ATV is necessary for safe and successful use of the

TreeChopper. The mounting bracket must be securely affixed to the frame of the ATV. If mounting to the frame and skid plate, the skid plate must be constructed of heavy metal. Do not attach to a plastic skid plate.

 If the metal skid plate is not flat and causes the Mounting Bracket and Cross Brace to not be flat against the frame, you cannot

safely mount to your ATV. It is very important to make sure the mounting bracket fits securely to the frame of the ATV

 Always install the Blade Guard when the TreeChopper is not in use.

Assembling and Installing the DR TreeChopper

Tools and supplies needed:

 Two 7/16" Wrenches  Two 9/16" Wrenches  Two 3/4" Wrenches  Gloves

Mounting for ATVs

Note: The following photos in this chapter focus on the installation of the Round

Tube Frame Kit #31956 but the steps describe all kits. Please refer to the Illustrations in Chapter 6 for accurate representation of the parts and assembly order of your kit.

1. Attach the Cutting Assembly to the Chassis (Figure 7) with two 1/2-20

Bolts, four 1/2" Flat Washers and two 1/2-20 Locknuts using two 3/4" Wrenches. Do not tighten the hardware completely to allow the Cutter Assembly to rotate independently of the Chassis.

Never attempt to mount the Universal Mounting Bracket to your ATV by drilling into the frame, skid plates, or mounting bracket.

2. Temporarily attach the Universal Mount to the Chassis using the two Pivot

Pivot Pins

Pins (Figure 8).

3. Slide the Universal Mount and Chassis under the ATV far enough so that the

non-removable lifting ring on the chassis is forward of the front of the winch (or other lifting device) by one to two inches. This allows for a slight angle during lifting (Figure 9). The Universal Mount should be centered as closely as possible to the center of the ATV (side to side).

Note: Included in your hardware kit is a removable 2nd lifting ring and hardware if you need to mount your TreeChopper farther forward. The two lifting rings locations are available to allow for more flexibility when finding an accessible position to attach the front mounting plate.

Note: Some plastic guarding or similar material may need to be removed to ensure an ideal mounting point to the Frame.

4. Look under the ATV to determine the closest location on the Frame where

the Universal Bracket and Cross Bar can be attached. If you have a plastic skid plate remove it from where the front and back mounting plates will fasten to the frame. Make sure that the Universal mount is tight to the frame or metal skid plate. If there is a plastic skid plate between the bracket and the frame it should be removed so that the bracket tightens flat against the ATV frame.

5. Unpin the Universal Mount from the Chassis and lift it into position against

the Frame to determine where the hardware can go around the Frame and into the slots of the Mount.

12 DR

TreeChopper™

6. Round Tube Frame (also some Polaris Frames): Lower the Universal Mount

and place a 2.25 Long U-Bolt around the Frame on both sides where it can rest against a stop on the rear facing side of the U-Bolt (Figure 10).

Square Tube Frame (also some Polaris Frames): Lower the Universal Mount and place a Square Frame Bracket over the top of the Frame on both sides where it (or the Bolts that will support it) can rest against a stop on the rear facing side of the Bracket. Insert a 3/8-16 X 2-3/4" Bolt down through each hole on the two brackets.

Beam Frame: Lower the Universal Mount and place a Beam Frame Bracket over the Frame where it (or the Bolts that will support it) can rest against a stop on the rear facing side of the Bracket. Insert a 3/8-16 X 4-1/2" Bolt down through each hole on the bracket.

Note: “U-Bolt Stop, Square Bracket Stop, or Beam Bracket Stop” is an area of the Frame where there is a cross piece or welding point that the U-Bolt , Square Frame Bracket, or Beam Frame Bracket will push against as the TreeChopper cuts into a tree. Never use a U-Bolt to mount the TreeChopper to a Square Tube Frame, or a Square Frame Bracket and Bolts to mount the TreeChopper to a Round Tube Frame.

9. Round Tube Frame (also some Polaris Frames): When you have determined

the best place to attach the Cross Bar to the Frame, remove the Cross Bar and place a 4" Long U-Bolt around the Frame on both sides to determine where it can rest against a stopping point on the Frame (Figure 12).

Square Tube Frame (also some Polaris Frames): When you have determined the best place to attach the Cross Bar to the Frame, remove the Cross Bar and place a Square Frame Bracket over the top of the Frame on both sides to determine where it (or the Bolts that will support it) can rest against a stopping point on the Frame.

Beam Frame: When you have determined the best place to attach the Cross Bar to the Frame, remove the Cross Bar and place a Beam Frame Bracket over the top the Frame to determine where it (or the Bolts that will support it) can rest against a stopping point on the Frame.

10. Reposition the Cross Bar against the Frame with the center Tabs over the

Universal Mount Tube (Figure 13). Insert the U-Bolts, or Bolts into the holes in the Cross Bar. Install a Flat Washer, Lock Washer and two Jam Nuts on each U-Bolt or Bolt using a 9/16" Wrench but leave the hardware fairly loose for now.

11. Align the holes in the Tabs of the Cross Bar to the nearest holes in the

Universal Mount Tube that will allow the Cross Bar to rest tight against the Frame. Install the 3/8-16 X 2-3/4" Bolt with a Flat Washer through the Tab holes and Mount Tube. Install a Flat Washer and Locknut on the end of the Bolt but only screw on by Hand.

Adjusting Bolt

Important!

Make sure the cutting assembly is properly adjusted using the two Adjuster Bolts on the back of the Cutting Head Assembly as described below. This adjustment should be made on a flat, hard surface such as concrete. The wheels of the ATV must be on the same flat surface that you are adjusting the Cutter Assembly angle to. These Bolts should be adjusted so that the front forks of the Cutting Head Assembly are slightly pitched down. This enables the Cutting Head Assembly to stay parallel to the ground when accelerating the ATV through the tree.

1. Lower the Cutting Head Assembly with your lifting device until the forward

end of the Head just touches the concrete (Figure 17).

2. Measure from the back end of the Cutting Head Assembly to the concrete.

It should be 1" off the concrete.

3. If the back end of the Cutting Head Assembly is not 1" from the concrete,

loosen the adjuster Nut and turn the adjuster Bolts in or out equally until the back end of the Cutting Head Assembly is 1" from the concrete when the front end is just touching.

4. Tighten the Jam Nut when adjustment is complete.

Removal and Installation of the Cutter Assembly

The TreeChopper can be quickly and easily installed or removed from the Universal Mount. To remove the TreeChopper simply remove the Hairpin Cotter Pins and Pivot Pins to drop the Chassis down onto the ground (Figure 14 on page 14). The Head Assembly and Chassis can now be pulled away from the ATV. Install in the reverse order.

To avoid injury to yourself as well as others, you must read, understand and follow the warnings listed in “Chapter 1 General Safety Rules” before operating an ATV equipped with your TreeChopper.

It may be helpful to better familiarize yourself with the features of your TreeChopper by reviewing Figure 1 in Chapter 2 before beginning the steps outlined in this chapter.

Before You Begin

 The TreeChopper can safely cut trees up to four inches in diameter and very close to ground level which is necessary to lessen

the possibility of re-growth.

 Before operating check the area where the TreeChopper will be used. If rocks or other debris will hinder access to the tree to be

cut check for other angles of approach or move the rocks and debris. Keep people, livestock and pets out of the cutting area.

 Always start out cutting small trees, less than 2" in diameter to familiarize yourself with the necessary actions, speed and

techniques to cutting trees with the TreeChopper. Once you have become comfortable with cutting smaller trees, you can move on to larger trees.

 Learn how to properly operate your ATV prior to using the TreeChopper.  Do not attempt to cut Trees with trunks larger than a 4 inch diameter.  Always make sure your ATV is in Four Wheel Drive and in Low Gear prior to cutting a Tree.

Operation

1. The TreeChopper can be raised and lowered by attaching a lifting device

(winch, ratchet strap, chain) and using one of the hooks on the chassis (Figure 18). This allows for quicker travel to and from the cutting areas while the TreeChopper is in the raised position. Remember, the TreeChopper must be on the ground and properly adjusted prior to cutting.

2. Before beginning to cut, turn off your ATV and set the TreeChopper on the

ground, making sure the winch line or other lifting device is loose. The TreeChopper will float along the terrain. This allows for the TreeChopper to cut close to the ground.

3. Remove the blade guard and visually inspect the unit. Make sure bolts are

tight and the circular blades are not obstructed.

4. When first learning how to operate the TreeChopper and becoming

comfortable with its use, select small trees 2 inches in diameter or less. It is important to get experience and establish a comfort level by cutting smaller trees first.

5. Always make sure that the TreeChopper is lined up so that the trunk of the

tree is center to the cutting blades. To be sure the TreeChopper is centered, slowly drive into the tree to "bump" it to check that the tree can clear the front blades (indicating that the tree is less than 4" in diameter) and that the tree is against the rotating Circular Blades. Once the tree trunk is centered and you have cleared the area of debris you are ready to cut.

Note: If the tree is unable to pass by the Front Blades, the tree may be larger than 4" in diameter at the trunk. This is an indication that you will not be able to cut the tree, or that there is a hidden obstacle, such as a rock, stump, or other object that

16 DR

TreeChopper™

would impede the cut. If there are no hidden obstacles impeding the cut, you may be able to approach the tree from a different angle to "bump" it and find that the trunk in that area is less than 4" in diameter.

6. Back your ATV away from the tree to approximately 8 to 10 feet. Accelerate the ATV in a forward motion through the tree.

Impact should be minimal. Once you have gained confidence and experience with tree trunks 2 inches in diameter and less you should be ready to cut bigger trees with trunks of up to 4 inches. You will also find that you are able to cut trees at a steady pace as you become comfortable identifying chop-able trees while in motion.

Note: After cutting, wash the TreeChopper with low pressure water spray. After washing, spray lubricating oil or silicone on the blades to

prevent rusting.

PROCEDURE

BEFORE EACH USE

AFTER FIRST 20 TREES

AFTER EACH

USE

Check General Equipment Condition



Check if Cutting Blades are dull or damaged (if damaged replace immediately)



Remove debris wrapped around Cutter Blades.



Check and adjust Cutting Blades



Lubricate Cutting Blades



Before performing any maintenance procedure or inspection, stop the ATV and put it in park, lower the TreeChopper to the ground, turn the ATV ignition to the “Off” position, remove the key and set the emergency brake.

 Never use a grinding wheel to sharpen the Blades. The heat produced from grinding will affect the Blade strength causing it

to break during use creating a hazard for the ATV and the driver.

 Wear gloves to protect your hands from sharp blade edges.  Wear safety glasses to protect your eyes from flying metal shavings.

Regular maintenance is the way to ensure the best performance and long life of your machine. Please refer to this manual for maintenance procedures.

Regular Maintenance Checklist

Protecting the Cutting Blades

Supplies Needed:

 Silicone Spray Lubricant

1. After use, clean the Blades of any debris and coat with silicone spray lubricant on all Blade surfaces to prevent rusting.

Note: Always have the Blade Guard installed over the Blades when the TreeChopper is not in use.

Sharpening the Cutting Blades

Tools and Supplies needed:

 Flat File  Leather Gloves  Safety Glasses

1. File the cutting edges of the Blades.

Note: Do not sharpen to a razor sharp edge.

 Wear gloves to protect your hands from sharp blade edges.

Tools and Supplies needed:

 Two 3/4" Wrenches  9/16" Wrench  Leather Gloves

1. Place the Cutter Head Assembly flat on the ground and remove the Bolt, Flat

Washers and Locknut from the two pivot points using two 3/4" Wrenches (Figure 19).

2. Remove the two Coupling Nuts that secure the Front Circular Blades with a

3/4" Wrench (Figure 20).

3. Remove the two Adjustment Pin Bushings that were under the Coupling

Nuts.

4. Remove the 18 Locknuts that secure the Upper Cutting Plate to the Lower

Cutting Plate using a 9/16" Wrench.

5. Pull the Upper Cutting Plate away from the Lower Cutting Plate.

Note: Take note of all Shim and Spacer locations for reassembling.

6. Remove the front and rear Shims (Figure 21).

Note: The front Triangular Blades can be flipped so the unused rear facing sharper

edge is now facing forward to minimize sharpening time. However when both edges are dull the entire cutting edge will need sharpening.

7. Remove and replace the Blades as needed.

Note: Ensure that the Circular Blade Bushings are in place when the Blades are

installed.

8. Reassemble the Cutter Head Assembly in the reverse order that it was

disassembled.

9. Perform a Circular Blade adjustment before tightening Coupling Nuts and

18 Locknuts mentioned in steps 2 and 4 (see next section “Front Circular Blade Adjustment”).

 Wear gloves to protect your hands from sharp blade edges.

Tools and Supplies needed:

 1/2" Breaker Bar and 3/4" Socket  9/16" Wrench  Leather Gloves

1. Loosen the Coupling Nuts at the center of each circular Blade with a 1/2"

Breaker Bar and 3/4" Socket (Figure 22).

Note: Keep the spaces between the circular Blades and rear Blade the same on both sides of rear Blade when adjusting in next step.

2. Loosen the Jam Nuts and adjust the Bolts with two 9/16" Wrenches so the

two Circular Blades are close enough together that a piece of paper can be dragged through with some resistance but without ripping or being cut.

3. When adjustment is accurate, firmly tighten the two Coupling Nuts using a

1/2" Breaker Bar and 3/4" Socket.

4. Tighten the Jam Nuts against the Frame to hold the end of the Bolt against

the Adjustment Pin Bushings.

Note: The two Circular Blades must rotate. Make sure that the Blades are not obstructed and are rotating on the Bushings.

SYMPTOM

POSSIBLE CAUSE

Cutter Head Assembly is off center

 Attaching hardware from mount to frame is loose; tighten hardware.  A pivot pin has pulled out of chassis and mount; reattach pin.

Trees becoming harder to cut

 Blades need sharpening; sharpen blades.  Blades are damaged; replace blades as needed.  Blades are out of adjustment; adjust blades.  Circular Blades are not spinning freely; clean the top and underside of the Blades. Never

loosen hardware in an attempt to allow the blades to rotate.

Trees are not being cut as close to the ground

 Cutter head assembly pivot needs adjustment; readjust bolts and jam nuts as required.
