Figure 5. Height Adjustment with Caster Arm Spacers
TRACTOR TOP LINK ADJUSTMENT
When the cutting height is set, adjust tractor top link
until mower top link attachment point (A) is aligned ver-
tically with mower hitch pin (B), Figure 6.
Adjust tractor top link so mower is level between caster
wheel and ground (dimension C), Figure 7. This will
allow the mower to follow ground contour.
The mower has three lower hitch plate attachment
points (D), Figure 6. It may be necessary to change the
mower hitch plate attachment point to obtain proper tire
clearance and/or lift height.

FRONT CASTER ARM CONFIGURATION
For PRD6000 & PRD7200 only
The front casters can be set in two positions. Figure 8
shows the two possible configurations for the
PRD6000 and PRD7200 front caster arms.
●
The inner position allows the outside edge of the
mower to be used for trimming under shrubs or
fences.
●
The outer position provides the most clearance for
rear tractor tire interference.
To change configurations, remove the cap screws and
nuts and move the arms from one side of the wheel rail
to the other. Secure with same hardware.
The rear caster arms should be mounted as shown.
NOTE: The PRD8400 front caster arms are fixed and
cannot be changed.
