OPERATION
7.2 Lift Type Models
Adjustment of the wheel bar combined with the tractor lift arms maintain cutting height. The 3-Point Hitch is
fitted with a floating link to reduce any load transferred to top link. The tractor lift should be set to correct level
to maintain correct height at front of machine.
Machine should be held level by tractor lift while mowing. Link float may be locked out by reversing center lock
plate in link assembly. This lock plate should only be used in level conditions and on tractors which are unable
to maintain lift level.
7.3 Semi-Mount Models
The cutting height is maintained with a combination of tractor 3-Point Lift adjustment and wheel bar
adjustment. Individual caster adjustment is to level caster pivot pin angle perpendicular with the ground, for
proper operation. Tractor should be attached to lower hitch point only. Always use a quick hitch to attach to
mower otherwise driveline failure may result.
8. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be
dirt free and greased for attachment.
To connect the mower driveline to the tractor
PTO output shaft, pull the driveline yoke collar
back and align the grooves and splines of the
yoke with those of the PTO shaft. Push the
driveline yoke onto the PTO shaft, release the
locking collar, and position the yoke until the
locking collar balls are seated onto the PTO
shaft. Push and pull the driveline back and forth
several times to ensure a secure attachment.
After the driveline is securely attached, place the
tractor PTO master shield back in the operating
position. OPS-R-0003
When attaching the Implement input driveline to the Tractor PTO, it is important that the
connecting yoke spring activated locking collar slides freely and the locking balls are seated
securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement.
