Checking the Rear Axle Gear Box
Lubricant
Service Interval: Every 400 hours
The gear box 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 16 oz (0.5 l).
Visually inspect for leaks daily.
1. Position the machine on a level surface.
2. Remove the check/fill plug from the left side of the
gear box (Figure 15) and make sure that lubricant
is up to the bottom of the hole. If the level is low,
add enough lubricant to bring the level up to the
bottom of the hole.

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
WARNING
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 85-100
ft-lb (115-136 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
Center 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
the height-of-cut on the front cutting unit, position the
castor wheel axles in the upper or lower holes of the
castor forks, add or remove an equal number of spacers
from the castor forks, and secure the rear chain to the
desired hole.
1. Start the engine and raise the cutting units so that
the height-of-cut can be changed. Stop the engine
and remove the key after the cutting unit is raised.
2. Position the castor wheel axles in the same holes
in all castor forks. Refer to the following chart to
determine the correct holes for the setting.
