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.
NOTE: Clean off mower deck before servicing.
BLOCKING METHODS
Jackstands, with a load rating of 1,000 pounds (454 kg)
or more, are the only approved blocking device for this
mower. A minimum of four jackstands, located under
the mower as shown in Figure 6, must be installed
before working underneath this unit. Do not position
jackstands 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.
Tighten tractor lower 3-point arm anti-sway mecha-
nisms to prevent side to side movement.
When blocking, you must consider overall stability of
the unit. Just placing jackstands under the unit will not
ensure your safety. The working surface must be level
and solid to support the weight on the jackstands.
Ensure jackstands are stable both top and bottom, and
mower is approximately level. With full mower weight
lowered on jackstands, test blocking stability before
working underneath mower.

LUBRICATION INFORMATION (Figure 7)
Figure 7 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.
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, concern,
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.
