4. Have another person carefully push down on the push
arm until the holes in the ball joint mount line up with
the holes in the castor arm. Immediately slide a 4 x 4
inch block of wood between the top of the push arm
and the underside of the chassis.
WARNING
Sudden release of the push arm could cause
injury.
Make sure that the wooden block does not
slip out.
5. Secure the ball joint mount and chain bracket to the
castor arm with the capscrews, flat washers, and flange
nuts previously removed. Position the flat washers to
the outside of the castor arm. Mount the chain bracket
in the forward set of holes.
6. Tighten the large jam nut securing the ball joint to the
push arm. When tightening the jam nut, hold the ball
joint straight to permit proper oscillation during raising
and lowering of the cutting unit. Carefully remove the
wood block holding the push arm down.

Connecting the Drive Shaft to
the Cutting Unit Gear Box
Parts needed for this procedure:
2
Bolt, 5/16 x 1-3/4 inches
2
Locknut, 5/16 inches
2
Roll pin, 3/16 x 1-1/2 inches
Procedure
Important: The drive shaft yokes must be exactly in
line with each other when the outer yoke is installed on
the gear box splined PTO shaft. Remove the sleeve and
change the yoke position if the alignment is not correct.
Misalignment of the two yokes will shorten the life of
the drive shaft and cause unnecessary vibration when
the cutting unit is operated.
1. Line up the holes in the yoke and input shaft of the
gear box. Slide the yoke onto the shaft and secure them
together with a roll pin and 2 capscrews (5/16 x 1-3/4
inches) and locknuts (5/16 inch) (Figure 8).

2. Yokes in phase
2. Mount the PTO shield to the top of the cutting unit
gear box mounting plate with the 2 self-tapping screws
previously removed.
