OWNER SERVICE
Before servicing, adjusting, repairing or unplug-
ging, stop tractor engine, place all controls in neu-
tral, set park brake, remove ignition key, and wait
for all moving parts to stop.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Your dealer can supply original equipment
hydraulic accessories and repair parts. Substitute
parts may not meet original equipment specifica-
tions and may be dangerous.
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.
The information in this section is written for operators
who possess basic mechanical skills. Should you need
help, your dealer has trained service technicians avail-
able. For your protection, read and follow all safety
information in this manual.
BLOCKING METHODS
Jack stands, with a load rating of 1,000 pounds or
more, are the only approved blocking device for this
mower. A minimum of four jack stands, located under
the mower as shown in Figure 8, must be installed
before working underneath this unit. Do not position
jack stands under wheels, axles, or wheel supports
because these components can rotate.
Do not work underneath unless it is properly attached
to tractor (see Operation Section), the brakes set, key
removed, and the mower blocked securely. The
mounted unit will be anchored to minimize side to side
and front to rear movement. The pull-type unit will be
anchored front to rear.
For the mounted unit, tighten tractor lower 3-point arm
anti-sway mechanisms to prevent side to side move-
ment.
For the pull-type unit, raise mower with the standard
ratchet adjustment link or the optional hydraulic cylin-
der. When the optional hydraulic cylinder is installed
the standard equipment transport bar must be pinned
in the raised position. With either the ratchet adjust-
ment link or the optional hydraulic cylinder, lower
mower to transfer its weight to the jack stands, but do
not raise the rear wheels off of the ground.
When blocking, you must consider overall stability of
the unit. Just placing jack stands under the unit will not
ensure your safety. The working surface must be level
and solid to support the weight on the jack stands.
Ensure jack stands are stable both top and bottom, and
mower is approximately level. With full mower weight
lowered on jack stands, test blocking stability before
working underneath mower.

LUBRICATION INFORMATION (FIGURE 9)
Figure 9 shows the lubrication points. The accompany-
ing chart gives the frequency of lubrication in operating
hours, based on normal conditions. Severe or unusual
conditions may require more frequent lubrication.
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
Use SAE 90W gear lube in gearbox. Check gearbox
daily for evidence of leakage at both seals and the gas-
ket between the housing and cover. If leakage is noted,
repair immediately. There may be a small amount of
lube emitted from the vent plug; this is not considered
leakage. Check the gearbox every day using the dip-
stick. Oil level is to be up to the ring but not over. Over-
filling the gearbox will cause the excess gear lube to
blow out vent plug. The gear lube could then ruin the
belt.
Use a lithium grease of No. 2 consistency with a MOLY
(molybdenum disulfide) additive for all locations. Be
sure to clean fittings thoroughly before attaching
grease gun. When applied according to the lubrication
chart, one good pump of most guns is sufficient. Do not
overgrease.
Daily lubrication of the driveline slip joint is necessary.
Failure to maintain proper lubrication can result in
