Table of Contents

Operator’s Responsibilities

Hazard control and accident prevention are dependent 

upon the awareness, concern, prudence, and proper 

training involved in the operation, transport, storage, and 

maintenance of the Stump Grinder. Therefore, it is 

absolutely essential that no one operates the Stump 

Grinder unless they are age 16 or older and have read, 

fully understood, and are totally familiar with the 

Operator’s Manual. Make sure the operator has paid 

particular attention to:

Important Safety Information

page 11

Section 2: Adjustments, 

page 22

Section 3: Operating,

Perform the following inspections before using your 

Stump Grinder.

Safety Information

DANGER

!

To avoid serious injury or death:  

Never make contact with underground utilities such as 

electrical power lines, gas lines, phone lines, etc. They can 

cause serious injury or death from electrocution, explosion, 

or fire. If in doubt, call 811 (USA) before digging so that 

they can mark the location of underground services in the 

area. For contact information, see Dig Safe in the 

“Important Safety Information” starting on page 1.

Always secure equipment with solid, non-concrete supports 

before working under it. Never go under equipment 

supported by concrete blocks or hydraulics. Concrete can 

break, hydraulic lines can burst, and/or hydraulic controls 

can be actuated even when power to hydraulics is off.

Operating Checklist

4

Check

Ref.

Read and follow all safety rules carefully. 

Refer to “Important Safety Information”.

Page 1

Make sure all guards and shields are in place. 

Refer to “Important Safety Information”.

Page 1

Make sure there are no hydraulic leaks. Refer 

to “Avoid High Pressure Fluids Hazard”.

Page 3

Read and follow all operating instructions. 

Make sure operator understands how to 

operate the Stump Grinder. Refer to 

“Section 2: Adjustments”.

Page 22

Read and make all required adjustments. Be 

sure all pins have been installed and secured.

“Section 3: Operating”

Page 23

Read and follow all maintenance instructions. 

Refer to “Section 4: Maintenance & 

Lubrication”.

Page 28

Check Stump Grinder initially and periodically 

for loose bolts and pins. 

Refer to “Torque Values Chart”.

Page 38

Do not engage power take-off while hooking-up or 

unhooking the driveline, or while someone is standing near 

the driveline. A person’s body and/or clothing can become 

entangled in the driveline.

Do not use a power take-off adapter. The adapter will 

increase strain on the tractor’s power take-off shaft causing 

possible damage to shaft and driveline. It will also defeat 

the purpose of the tractor’s power take-off shield.

All guards and shields must be installed and in good 

working condition. Loose clothing caught on rotating 

components can pull a person into the machinery. Hands 

and other body extremities can become entangled in the 

machinery. Objects can be thrown by rotating components.

WARNING

!

To avoid serious injury or death:  

Hydraulic fluid under high pressure can penetrate the skin 

and/or eyes causing a serious injury. Wear protective gloves 

and safety glasses or goggles when working with hydraulic 

systems. Use a piece of cardboard or wood rather than 

hands when searching for leaks. A doctor familiar with this 

type of injury must treat the injury within a few hours or 

gangrene may result. DO NOT DELAY. 

Allow only persons to operate this implement who have 

fully read and comprehended this manual, who have been 

properly trained in the safe operation of this implement, and 

who are age 16 or older. Serious injury or death can result 

from the inability to read, understand, and follow 

instructions provided in this manual. 

Never carry riders on the implement or tractor. Riders can 

obstruct the operator’s view, interfere with controls, be 

pinched by moving components, become entangled in 

rotating components, struck by objects, thrown about, fall 

off and be run over, etc.

Keep body, body extremities, loose clothing, pull strings, 

etc. away from pinch points such as rotating, extending, 

and/or retracting components. Secure pinch point areas to 

ensure they will not move before working on or near them.

Be careful when working areas where obstructions can be 

hidden. Always mark potential hazards with a visible flag. 

Travel slowly through high risk areas and be prepared to 

stop immediately should implement make contact with a 

solid object.

Perform scheduled maintenance. Check for loose 

hardware, missing parts, broken parts, structural cracks, 

and excessive wear. Make repairs before putting the 

implement back into service.

Do not alter implement or replace parts on the implement 

with other brands. Other brands may not fit properly or 

meet OEM (Original Equipment Manufacturer) 

specifications. They can weaken the integrity and impair the 

safety, function, performance, and life of the implement. 

Replace parts only with genuine OEM parts.

Do not operate a broken or bent driveline. Such a driveline 

will break apart while rotating at high speeds and can cause 

serious injury or death. Always remove the implement from 

use until the damaged driveline can be repaired or replaced.
