(Safety Rules continued on next page)

Safety is a primary concern in the design and

manufacture of our products. Unfortunately, our

efforts to provide safe equipment can be wiped

out by an operator’s single careless act.

In addition to the design and configuration of

equipment, hazard control and accident preven-

tion are dependent upon the awareness, con-

cern, judgement, and proper training of

personnel involved in the operation, transport,

maintenance, and storage of equipment.

It has been said, “The best safety device is an

informed, careful operator.” We ask you to be

that kind of operator.

index of 80W or 90W and an API service rating of GL–

4 or GL–5.

Fill gearbox with .33 gallons (2.64 pints) of SAE 80W or

90W gear lube. Check gearbox daily for evidence of

leakage, and contact your dealer if leakage occurs.

Driveline Lubrication

1. Lubricate the driveline slip joint every eight

operating hours. Failure to maintain proper

lubrication could result in damage to the U-joints,

gearbox, and driveline. See Figure 5.

2. Lower stump grinder to ground, disconnect

driveline from tractor PTO shaft, and slide halves

apart but do not disconnect from each other.

3. Apply a bead of grease completely around male

half where it meets female half. Slide drive halves

over each other several times to distribute grease.

STUMP GRINDER TOOTH REPLACEMENT

NOTE: Replace teeth whenever they become dam-

aged, broken, or excessively worn. Excessively worn

cutting edges greatly decrease cutting efficiency.

NOTICE

■

Never operate the stump grinder with missing

teeth.

1. Use a 15/16 socket wrench and remove the 5/8"

jam nuts as shown in Figure 6.

2. Remove hex nut from tooth and remove tooth.

3. When installing new teeth, torque the 5/8" jam nuts

to 170 lbs-ft (230 N-m).

Figure 6. Tooth Installed

SLIP CLUTCH ADJUSTMENT

The slip clutch is designed to slip so that the gearbox

and driveline are protected if the cutter strikes an

obstruction.

A new slip clutch or one that has been in storage over

the winter may seize. Before operating the grinder,

make sure it will slip by performing the following opera-

tion:

1. Turn off tractor engine and remove key.

2. Loosen eight 10 mm cap screws (6) to remove all

tension from pressure plate (5). Springs should

rotate freely.

3. Place a mark on edge of lining rings (3).

4. Hold flanged hub (4) solid and rotate driveline to

make sure clutch slips. Check marks on edge of

lining rings to see if they have moved.

5. If clutch does not slip freely, disassemble and clean

surface of flanged hub (4), flange yoke (1), and

pressure plate (5).

6. Reassemble clutch.

7. Tighten springs (7) until they are compressed to

the 1.26 inches shown in Figure 7.

8. If a clutch continues to slip when the springs are

compressed to the 1.26 inch dimension, check

lining rings (3) for excessive wear. Rings are 1/8"

when new. Replace rings after 1/32" wear to

ensure proper operation.

DEALER SERVICE

The information in this section is written for dealer ser-

vice personnel. The repair described here requires

special skills and tools. If your shop is not properly

equipped or your mechanics are not properly trained in

this type of repair, you may be time and money ahead

to replace complete assemblies.



Keep hands and body away from pressurized

lines. Use paper or cardboard, not hands or other

body parts to check for leaks. Wear safety goggles.

Hydraulic fluid under pressure can easily penetrate

skin and will cause serious injury or death.



Make sure that all operating and service person-

nel know that if hydraulic fluid penetrates skin, it

must be surgically removed as soon as possible by

a doctor familiar with this form of injury or gan-

grene, serious injury, or death will result. CON-

TACT A PHYSICIAN IMMEDIATELY IF FLUID

ENTERS SKIN OR EYES. DO NOT DELAY.



Never perform service or maintenance with

engine running.



Keep all persons away from operator control

area while performing adjustments, service, or

maintenance.



Check that all hardware is properly installed.

Always tighten to torque chart specifications

unless instructed otherwise in this manual.



Always wear relatively tight and belted clothing

to avoid getting caught in moving parts. Wear

sturdy, rough-soled work shoes and protective

equipment for eyes, hair, hands, hearing, and head;

and respirator or filter mask where appropriate.

GEARBOX MAINTENANCE

NOTE: Read this entire section before starting any

repair. Many steps are dependent on each other.

NOTE: Repair to this gearbox is limited to replacing

bearings, seals, and gaskets. Replacing gears, shafts,

and a housing is not cost effective. Purchasing a com-

plete gearbox is more economical.

Inspect gearbox for leakage and bad bearings. Leak-

age is a very serious problem and must be corrected

immediately.

Bearing failure is indicated by excessive noise and

side-to-side or end-play in gear shafts.

Cutting Wheel Removal

1. Position stump grinder on a hard level surface with

main frame crossbrace firmly on the ground.

2. Remove hardware and side shield from the right

side of the cutter frame.

3. Remove cotter pin and slotted hex nut from end of

horizontal gearbox shaft and remove wheel and

hub (Figure 10).

NOTE: You will need to use a heavy-duty puller to

remove cutting wheel and hub from gearbox shaft.

Cutting Wheel Installation

Slide cutting wheel onto gearbox shaft. Install washer

and nut. Torque nut to 200 ft-lbs. Replace cotter pin.

Replace side shield.

Figure 10. Cutting Wheel and Hardware

Gearbox Removal

1. Disconnect and remove the driveline from the

tractor.

2. Disconnect and remove the driveline from the

gearbox.

3. Remove the four bolts that attach gearbox to stump

grinder and remove gearbox.

Seal Replacement

Recommended sealant for gearbox repair is Perma-

tex

Aviation 3D Form-A-Gasket or equivalent.

Leakage can occur at the vertical or horizontal gaskets

and shaft seals.

Leakage at the horizontal gasket or seal can be

repaired without removing the gearbox from the cutter.

Seal Installation

NOTE: Proper seal installation is important. An improp-

erly installed seal will leak.

1. Clean area in housing where seal outer diameter

(OD) seats. Apply a thin coat of Permatex.

2. Inspect area of shaft where seal seats. Remove

any burrs or nicks with an emery cloth.

3. Lubricate gear shaft and seal lips.

4. Place seal squarely on housing, spring-loaded lip

toward housing. Select a piece of pipe or tubing

with an OD that will sit on the outside edge of the

seal but will clear the housing. Tubing with an OD

that is too small will bow seal cage and ruin seal.

5. Carefully press seal into housing, avoiding

distortion to the metal seal cage.
