4.3 GENERAL LUBRICATION
Control Linkage Lubrication
Every 25 hours of operation put a drop of engine oil on
the pivots of the throttle lever, the direction control
lever, the gear shift lever, the PTO control, and range
shift handle.
NOTE: There are no grease fittings on the tractor.
Transmission
Capacity: 5 U.S. Quarts (4.7 liters)
Grade: SAE 30W API service class SF or higher
Viscosity: Summer: SAE 30W or SAE 10W-30
Winter: (32
o
F or below) SAE 10W or
SAE 10W-30
• After every 100 hours of operation, check the level
of the lubricant in the transmission. Never operate
the tractor when the transmission oil level is below
the "LOW’ mark on the dipstick.
• Stop the engine and raise the hood. Make sure that
the tractor is level. Clean the dipstick tube and the
dipstick (Figure 2). Remove the dipstick, wipe it
with a clean cloth or towel and put it back in the
tube. Pull the dipstick out again and look at the oil.
• If the oil level is below the low mark on the dipstick,
clean the area around the filler plug and remove
the filler plug. Add new clean lubricant until the
dipstick indicates that the oil level is correct. See
specification. Install the filler plug and dipstick.
4.4 FORWARD-REVERSE CLUTCH
ADJUSTMENT
• After 25 hours of operation, check the adjustment
of the forward-reverse clutch.
• The reverse clutch is adjusted correctly when the
direction control lever stops 15 degrees past
vertical to the rear. The lever should return to
neutral position from reverse when adjusted
correctly.
• To adjust the reverse clutch, loosen the control
extension rod jam nuts on the end of the fwd-rev
control rod. Adjust the rear nut so that the direction
control lever stops 15 degrees past vertical to the
rear. Hold the rear nut and jam with the forward nut
(Figure 3).
• The forward clutch is adjusted correctly when the
direction control lever is in the full forward position
and the large spring has a coil clearance of .010"
(.254 mm).
