NOTE: There is not a fuel shutoff valve in the fuel system. To stop the fuel flow from the fuel tank, the fuel inlet hose
to the fuel filter has to be removed from the fuel filter base and a plug installed or the fuel hose needs to be crimped
shut to shutoff the fuel flow.
Hydraulic oil filter
NOTE: Replace the hydraulic system oil filter after the first
50 hours of operation, and then following every 300 hours
of operation thereafter.
The hydraulic system uses a spin-on type oil filter, located
on the left side of the tractor underneath the operator's plat-
form. To replace the filter
(1) :
1. Unscrew the used oil filter and discard.
2. Coat the gasket on the new filter with a film of clean oil.
Screw the filter into place until the gasket contacts the
sealing surface, then tighten the filter by hand approxi-
mately three-quarters of a turn. Do not overtighten.
3. Start the engine and check the filter for leaks.
4. Stop the engine and check the hydraulic system oil
level. Add oil if necessary.
