Figure 30 

1. Traction check/high pressure relief valve 

1. Park the machine on a level surface, lower cutting 
units, engage parking brake and stop the engine. 

2. Remove the check/high pressure relief valve hex plug 
(Fig 30). 

3. Remove the valve cartridge assembly. Inspect the 
valve and mating seat in the housing for damage or 
foreign material. It will be necessary to replace the 
center section if the seat is damaged. 

IMPORTANT: The relief valves are factory set and 
should not be tampered with, except to replace the 
entire valve cartridge. 

2. Reel check/high pressure relief valve 

4. The valve cartridge is retained in the special plug by 
a circlip. The check valve spring may be removed from 
the special plug by pulling out at a slight angle. When 
reassembling, install the check valve spring into the 
special plug with its larger diameter toward the plug, and 
snap the valve cartridge into position in the plug. 

5. Reinstall the valve cartridges with o-rings into the 
housing and tighten the plugs to a torque of 30 to 
50 ft-lb. 

6. Before starting the engine check the oil level in the 
differential housing and add the correct oil as necessary. 
Start the engine and let it run for one to two minutes, 
then turn the engine off and check the oil level again. 
Check the transmission for leaks.
