The information in this sectionis 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.
CAUTION
Always wear relatively tight and belted clothing to avoid entanglement in moving parts. Wear sturdy,
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.
