Driveline Interference Check
1. Check for clearance between driveline and cutter
deck.
2. Slowly lift cutter and observe driveline. If clearance
between driveline and cutter deck is less than 1
inch, shorten top link or limit upper travel of lower
hitch arms. Refer to tractor operator's manual for
instructions.
CUTTING HEIGHT ADJUSTMENT
On pull-type or semi-mounted units with
optional hydraulic cutting height adjustment, use a
single-acting cylinder with a maximum extended
length of 28-1/4" (718 mm) from attaching point
center to center.
Cutting height range is from 2" to 13". A hydraulic cylin-
der or ratchet jack is available for cutting height adjust-
ment.
When selecting a cutting height, you should consider
the area of operation. If the ground is rolling and has
mounds the blades could contact, set the cutting height
accordingly.
NOTICE
■ Avoid ground contact with blades. Striking
ground with blades produces one of the most dam-
aging shock loads a cutter can encounter. If this
occurs repeatedly, the cutter, driveline, and gear-
boxes will be damaged.
Pull-Type Units
To adjust cutter for normal mowing, select a cutting
height (example: 4 inches). Blades are approximately
1-3/4" above bottom of cutter. Dimension A plus 1-3/4"
equals the cutting height.
Using any of the optional cutting height mechanisms,
raise or lower the tailwheel and set position A to 2-1/4"
to achieve a 4" cutting height.
Loosen the jam nut on the attitude rod that runs from
the tongue to the tailwheel. Adjust rod in or out until
position B is approximately 1/2 inch more than position
A. Refer to Figure 8.
Figure 8. Cutting Height Adjustment
Mounted & Semi-Mounted Units
To adjust cutter for normal mowing, select a cutting
height (example: 4 inches). Blades are approximately
1-3/4" above bottom of cutter. Dimension A plus 1-3/4"
equals the cutting height.
Adjust the tractor 3-point hitch to a distance of 2-1/4" at
position A to obtain a 4" cutting height. See Figure 8.
Using any of the optional height adjustment devices,
raise or lower the tailwheel to obtain 2-1/2 to 2-3/4
inches at position B.
