Checking the Rear Axle Lubricant
Service Interval: Every 400 hours
The rear axle is filled with SAE 85W-140 gear lube.
Check the oil level before the engine is first started and
every 400 hours thereafter. The capacity is 80 oz (2.4 l).
Visually inspect for leaks daily.
1. Position the machine on a level surface.
2. Remove a check plug from one end of the axle
(Figure 12) and make sure that the lubricant is up to
the bottom of the hole. If the level is low, remove
the fill plug (Figure 12) and add enough lubricant to

Checking the Tire Pressure

Service Interval: Before each use or daily
The tires are over-inflated for shipping. Therefore,
release some of the air to reduce the pressure. The
correct air pressure in the front and rear tires is 25-30
psi (172-207 kPa).
Important: Maintain even pressure in all tires to
ensure a good quality-of-cut and proper machine
performance. Do not under-inflate.
Checking the Torque of the Wheel Nuts
or Bolts
Service Interval: After the first 10 hours
Every 200 hours
Failure to maintain proper torque of the wheel
nuts could result in failure or loss of wheel and
may result in personal injury.
Torque the front wheel nuts and rear bolts to 85
to 100 ft-lb (115 to 136 N⋅ ⋅ ⋅ m) after 1-4 hours of
operation and again after 10 hours of operation.
Torque every 200 hours thereafter.
Adjusting the Height-of-Cut
Front Cutting Unit
The height-of-cut is adjustable from 1 to 5 inches (25
to 127 mm) in 1/2 inch (13 mm) increments. To adjust
