DEALER SERVICE
The information in this section is written for dealer ser-
vice personnel. The repair described herein 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.
NOTE: Clean off mower deck before servicing.
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.
Make certain all movement of equipment com-
ponents has stopped before approaching for ser-
vice.
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.
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 12, 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 mower unless it is properly
attached to tractor (see Operation section), the brakes
set, key removed, and the mower blocked securely.
The unit will be anchored to minimize side-to-side and
front-to-rear movement.
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.

BLADE SPINDLE
Blade Spindle Repair Tips
As a reference point, the grease fitting is in the top por-
tion of the spindle housing.
To minimize wear, the bearing cups, cones and sleeves
are press fit to the shaft and will require a press or sim-
ilar device for removal.
When disassembling, support the housing casting to
prevent damage.
Remove bearing cups by placing a punch in housing
slots and driving cup out. Alternate punch positions
from side to side. Use care to prevent housing dam-
age.
Permatex Aviation Form-A-Gasket

or equivalent is
recommended as a sealant for spindle repair.
