The fuel filter (Fig. 4-9A & 4-9B) is installed in the fuel
line between fuel tanks and engine fuel pump. Replace filter
annually or after every 500 hours of operation, whichever
occurs first.
When replacing the fuel filter, check the fuel line hoses
and fuel shut-off valve grommet for any cracks or leaks.
On early units a fuel shut-off valve is located on the
outlet port of each fuel tank. (Fig. 4-10A) Close these
valves (turn clockwise) to prevent fuel flow to the engine.
Current production units have a fuel shut-off valve
attached to the crossmember next to the hour meter. (Fig. 4-
10B) Close this valve (center position) to prevent fuel flow
to the engine. Fig 4-10B shows the valve’s two other
positions.
Engine oil and filter
Check engine oil daily and after every 4 hours of
operation. Crankcase dipstick and oil filler tube are located
at the rear of the machine (Fig. 4-11A & 4-11B). Tractor
must be setting level when checking oil. Refer to engine
manual and maintenance schedule for oil recommendation
and capacities.
Change the engine oil and filter after the first 5 hours of
operation, per the engine manufacturer’s recommendations
