3. Add gear oil to the hole in the planetary and to the hole
in the brake, if necessary, to bring the oil up to the
proper level. Install the plugs.
4. Repeat steps 1–3 on the opposite gear assembly.
Checking the Rear Axle
Lubricant
The rear axle is shipped from the factory filled with SAE
85W-140 wt. 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 (Fig. 8)
and make sure that the lubricant is up to the bottom of
the hole. If the level is low, remove the fill plug (Fig. 8)
and add enough lubricant to bring the level up to the
bottom of the check plug holes.

Checking the Rear Axle Gear
Box Lubricant
The gear box is shipped from the factory filled with SAE
85W-140 wt. 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 (Fig. 9) 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

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
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 NVm) 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 center 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.
