DEALER SERVICE
The information in this section is written for dealer ser-
vice personnel. The repair described here 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.
Before working underneath, read manual
instructions, securely block up, and check stability.
Secure blocking prevents equipment from drop-
ping due to hydraulic leak down, hydraulic system
failure, or mechanical component failure.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Always wear relatively tight and belted clothing
to avoid entanglement 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 METHOD
Do not work underneath mower unless it is properly
attached to the tractor and blocked securely. When
properly attached, the unit will be anchored to minimize
front to rear movement.
Raise mower completely, set tractor brakes, turn
engine off, remove key, block tractor wheels front and
rear, and disconnect mower driveline from tractor.
The only approved blocking devices for this mower are
jackstands with a load rating of 1000 pounds or more.
One jackstand under each corner of the mower (four
total) must be installed before working underneath this
unit.
When blocking, you must consider overall stability of
the unit. Just blocking under the unit will not ensure
your safety. The working surface must be level and
solid to support the loaded weight of the jackstands.
Test jackstand stability before working under any por-
tion of the mower.

dle shaft.
