Danger
If the engine is started and the PTO shaft is
allowed to rotate, serious injury could result.
Do not start the engine and engage the PTO lever
when the PTO shaft is not connected to the gear
box on the cutting unit.
Installing the Castor Wheel
Assemblies
The thrust washers, spacers, and tensioning caps have been
installed on the castor wheel spindles for shipping.
1. Remove the tensioning caps from the spindle shafts and
slide off the spacers and thrust washers (Fig. 1 and 2).

height-of-cut and roll the cutting unit off of the pallet.

Installing the Lift Arms to the
Traction Unit
1. On one side of the traction unit, loosen (do not remove)
the wheel nuts securing the wheel and tire assembly to
the front wheel studs.
2. Jack up the machine until the front wheel is off of the
floor. Use jack stands or block the machine to prevent it
from accidentally falling.
3. Remove the wheel nuts and slide the wheel and tire
assembly off of the studs.
4. Mount a lift arm to the pivot bracket with a pivot pin
and cotter pin (5/32 x 1-3/4 in.) (Fig. 3). Mount the lift
arm with the ball joint end positioned outward.
5. Mount the rear of the lift arm to the lift cylinder with a
pivot pin and 2 cotter pins (supplied with the traction
unit).
