Operation 17
MAN0577 (6/29/2007)
5. Place the cutoff portion of the shield against the
end of the shaft and use it as a guide. Mark and cut
the shaft. See Figure 7.
6. Repeat step 5 for other half of drive.
7. File and clean ends of both drive halves.

Driveline Interference Check
1. Check for clearance between driveline and cutter
deck.
2. With driveline properly attached to tractor and
gearbox, 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
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.
Adjust top link to provide 1-1/4 inches of clearance
between the break link (2) and the rear of the lift links.
See Figure 8. This clearance will allow the cutter to
float over uneven terrain.
Figure 8. Cutting Height Adjustment
Pull-Type Units
On pull-type units with optional hydraulic cut-
ting 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.
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 dimension 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
dimension B is approximately 1/2 inch more than
dimension A. Refer to Figure 8.
