ꢀ Never go underneath equipment (lowered to the

ground or raised) unless it is properly blocked and

secured. Never place any part of the body under-

neath equipment or between moveable parts even

when the engine has been turned off. Hydraulic

system leak down, hydraulic system failures,

mechanical failures, or movement of control levers

can cause equipment to drop or rotate unexpect-

edly and cause severe injury or death. Follow Oper-

ator's Manual instructions for working underneath

and blocking requirements or have work done by a

qualified dealer.

Gearbox Lubrication

1. For gearbox, use a high quality gear oil with a

viscosity index of 80W or 90W and an API service

rating of GL-4 or -5 in gearboxes.

2. Fill gearbox until oil runs out the side plug on

gearbox. Check gearbox daily for evidence of

leakage, and contact your dealer if leakage occurs.

Driveline Lubrication

To minimize the potential hazards of working under-

neath the cutter, follow these procedures.

1. Lubricate the driveline slip joint every eight

operating hours. Failure to maintain proper

lubrication could result in damage to U-joints,

gearbox, and driveline.

1. Jackstands with a load rating of 1000 lbs or more

are the only approved blocking device for this

cutter. Install a minimum of four jackstands (shown

by Xs in Figure 12) under the cutter before working

underneath unit.

2. Lower cutter to ground, disconnect driveline from

tractor PTO shaft, and slide halves apart but do not

disconnect from each other.

Do not position jackstands under wheels, axles, or

wheel supports. Components can rotate and cause

cutter to fall.

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.

BLADE SERVICING

Blade Removal (Figure 13)

NOTICE

■ If blade pin is seized in crossbar and extreme

force will be needed to remove it, support crossbar

from below to prevent gearbox damage.

3. Align crossbar (8) with blade access hole in the

cutter frame. Remove cap screw, blade pin lock

clip, keyhole plate, and shims. Carefully drive pin

out of crossbar.

4. Rotate crossbar (8) and repeat for opposite blade.

Blade Installation (Figure 13)

CAUTION

ꢀ Your dealer can supply genuine replacement

blades. Substitute blades may not meet original

equipment specifications and may be dangerous.

3. Align crossbar (8) with blade access hole in cutter

frame. Apply a liberal coating of Never Seez^®or

equivalent to blade pin and crossbar hole. Make

sure blade offset is away from cutter. Push blade

pin through crossbar. Pin should rotate freely prior

to installing blade clip (15).

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

the winter may seize. Before operating the cutter, make

sure it will slip by performing the following operation:

Comer

1. Turn off tractor engine and remove key.

4. Install shims (13 & 16) over blade pin.

2. Loosen nuts on springs until the springs can rotate

freely, yet remain secure on the bolts.

NOTE: Only use enough shims to allow keyhole

plate (14) to slide into blade pin groove.

3. Mark outer plates of slip-disc clutch as shown in

Figure 15.

5. Install blade clip (15) over keyhole plate and into

blade pin groove.

4. Securely attach implement to the tractor and start

the tractor.

6. Secure into position with cap screw (35). Torque

cap screw to 85 lbs-ft.

5. Engage PTO for several seconds then quickly

disengage it.

7. Repeat steps for opposite side.

6. Turn tractor off and remove key.

NOTE: Blade should be snug but should swivel on

pin without having to exert excessive force. Keep

any spacers not used in the installation as replace-

ments or for future installation.

7. The friction lining plates should have "slipped".

Check the marks placed on the outer plates of the

slip-disc clutch in step 3 to make sure this is the

case.

Blade Sharpening

8. If clutch does not slip, check assembly for oil,

grease and debris. Clean if necessary.

NOTICE

■ When sharpening blades, grind the same

amount on each blade to maintain balance.

Replace blades in pairs. Unbalanced blades will

cause excessive vibration, which can damage

gearbox bearings. Vibration may also cause struc-

tural cracks to cutter.

9. Reassemble clutch and tighten bolts no more than

1/8 of a turn at a time until desired setting of 1.26"

on BB48X, BB60X and BB72X cutters is reached.

For BB84X cutters, set to 1.36". See Figure 15.

10. If excessive slippage continues, check lining plates

for excessive wear. They are 1/8" thick when new

and should be replaced after 1/32" of wear to

ensure proper operation.

1. Sharpen both blades at the same time to maintain

balance. Follow original sharpening pattern.

2. Do not sharpen blade to a razor edge—leave at

Walterscheid (BB84X Only)

least a 1/16" blunt edge.

1. Turn off tractor engine and remove key.

3. Do not sharpen back side of blade.

2. Remove driveline from tractor PTO.

3. Loosen six 10 mm cap screws (6) to remove all

tension from Belleville spring plate (5).

4. Hold clutch hub (3) solid and turn shaft to make

sure clutch slips.

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

the thrust plate faces (4), flange yoke (1), and

clutch hub (3).

6. Reassemble clutch. Tighten Belleville spring (5)

until it is against the thrust plate (4) of the clutch,

and then back off each of the six nuts by two full

revolutions. The gap between Belleville spring and

thrust plate should be 1/8" as shown in Figure 15.

Figure 14. Blade Sharpening

7. If a clutch continues to slip when the spring is

compressed to 1/8", check friction discs (2) for

excessive wear. Discs are 1/8" when new. Replace

discs after 1/16" wear. Minimum disc thickness is

1/16".

SLIP CLUTCH ADJUSTMENT

The slip clutch is designed to slip so that the gearbox

and driveline are protected if the cutter strikes an

obstruction.

DEALER SET-UP INSTRUCTIONS

Assembly of this cutter is the responsibility of the

Woods dealer. It should be delivered to the owner com-

pletely assembled, lubricated, and adjusted for normal

cutting conditions.

• This shielding is designed to reduce the risk

of thrown objects. The mower deck and protec-

tive devices cannot prevent all objects from

escaping the blade enclosure in every mowing

condition. It is possible for objects to ricochet

and escape, traveling as much as 300 feet (92 m).

The cutter is shipped partially assembled. Assembly

will be easier if aligned and loosely assembled before

tightening hardware. Recommended torque values for

hardware are located in the Bolt Torque Chart, page

56.

Complete Dealer Check Lists, page 34 when you

have completed the assembly.

ꢀ Make sure attachment is properly secured,

adjusted, and in good operating condition.

CAUTION

ꢀ Full chain, rubber, or steel band shielding must

be installed when operating in populated areas or

other areas where thrown objects could injure peo-

ple or damage property.

ꢀ 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;
