Connecting the Mower (Figure 4-2)
1. Make sure the tractor is equipped with the correct
PTO shaft. Change shafts if needed.
2. Shorten or remove the tractor drawbar to avoid in-
terference when raising and lowering the mower.
3. Board the tractor and start the engine. Position the
tractor to the mower with the 3-point lift arms posi-
tioned at the same height and to the outside of the
mower hitch pins. Note: Set the 3-point lift control to
"Position Control" so that the lift arms maintain a
constant height when attaching the mower. See the
tractor Operator's Manual for correct settings when
attaching 3-point equipment.
4. Turn off the tractor engine, set the parking brake,
place the tractor in park, and dismount.
5. One lift arm at a time, position the tractor lift arms
over the A-frame hitch pins. Insert lynch pins to re-
tain lift arms to the mower. Walk around to opposite
side and repeat procedure for remaining lift arm and
hitch pin.
6. Extend or retract the 3-point top link to align its end
hole with the holes of the mower's top link. Insert the
top link hitch pin and insert retaining pin into hitch
pin.
7. Adjust any lower link check chains, guide blocks, or
sway blocks to prevent the mower from swaying
side to side and possible contact with tractor rear
tires.
DRIVELINE ATTACHMENT (Figure4-4)
The driveline yoke and tractor PTO shaft must be dirt free
and greased for attachment. Connect the driveline yoke
with the Push Pin to the gearbox input shaft of the mower.
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, re-
lease 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 en-
sure a secure attachment.
When attaching the Implement input driveline to the Tractor PTO, it is important that the connect-
ing 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.
