18 Owner Service; Blocking Method; Lubrication Information - Woods BRUSHBULL BB48.30 Operator's Manual

The information in this section is written for operators
who possess basic mechanical skills. If you need help,
your dealer has trained service technicians available.
For your protection, read and follow the safety informa-
tion in this manual.
WARNING
■ Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
CAUTION
■ If you do not understand any part of this manual
and need assistance, see your dealer.
■ Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protec-
tive equipment for eyes, hair, hands, hearing,
and head; and respirator or filter mask where
appropriate.

BLOCKING METHOD

WARNING
■ Before performing any service or maintenance,
disconnect driveline from tractor PTO.
■ Never go underneath equipment (lowered to the
ground or raised) unless it is properly blocked
and secured. Never place any part of the body
underneath 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 unexpectedly and cause severe injury or
death. Follow Operator's Manual instructions
for working underneath and blocking require-
ments or have work done by a qualified dealer.
To minimize the potential hazards or working under-
neath the cutter, follow these procedures:
1. Jackstands with a load rating of 1000 lbs. or more
are the only approved blocking device for this cutter.
Install jackstands (shown by Xs in Figure 12) under
the cutter before working underneath unit.
Do not position jackstands under wheels, axles, or
wheel supports. Components can rotate and cause
cutter to fall.

2. Consider the overall stability of the blocked unit.
Just placing jackstands underneath will not ensure
your safety.
The working surface must be level and solid to
support the weight on the jackstands. Make sure
jackstands are stable, both top and bottom. Make
sure cutter is approximately level.
3. With full cutter weight lowered onto jackstands, test
blocking stability before working underneath.
4. If cutter is attached to tractor when blocking, set the
brakes, remove key, and block cutter before work-
ing underneath.
5. Securely block rear tractor wheels, in front and be-
hind. Tighten tractor lower 3-point arm anti-sway
mechanism to prevent side-to-side movement.

LUBRICATION INFORMATION

1. Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
2. See Figure 12 for lubrication points and frequency
or lubrication based on normal operating conditions.
Severe or unusual conditions may require more fre-
quent lubrication.
3. Use a lithium grease of #2 consistency with a MOLY
(molybdenum disulfide) additive for all locations
unless otherwise noted. Be sure to clean fittings
thoroughly before attaching grease gun. One good
pump of most guns is sufficient when the lubrication
schedule is followed.
Gearbox Lubrication
1. For gearbox, use a high quality gear oil with a vis-
cosity index of 80W or 90W and an API service
rating of GL–4 or –5 in gearboxes.
2. Fill gearbox until oil is above lower line on dipstick.
Check gearbox daily for evidence of leakage, and
contact your dealer if leakage occurs.
Driveline Lubrication
1. Lubricate the driveline slip joint every ten operating
hours. Failure to maintain proper lubrication could
result in damage to U-joints, gearbox, and driveline.
2. Lower cutter 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.
