Operation
3. The mower drive shaft connects to the tractor drive
shaft by a series of retracting balls located under the
locking ring (A, figure 5). When the locking ring is
released, the balls lock into a groove on the tractor
drive shaft. To connect the drive shaft, proceed as
follows:
A. Place the mower drive shaft barely onto the tractor
drive shaft. Turn the coupler (B, figure 5) to align
the splines.
B. Pull the locking ring (A, figure 5) back, then push
the mower drive shaft onto the tractor drive shaft,
past the groove.
C. Grasp the coupler and pull back. The locking ring
will snap forward into the locked position when the
balls are seated in the groove.
D. Test the connection by pulling back on the coupler.
You should not be able to pull it off.
4. Raise mower to mid-cut position. See figure 6. Hook
the chains (C) to the clevis (A) on each side of the
gear box. Insert pin (B) through clevis and chain, then
install hairpin clip (D) in pin. Hairpin clip should be
installed towards the inside as shown.
NOTE: When connecting mower deck to tractor, use 5
links of chain.
5. Start the engine and turn the front wheels straight
ahead. Using the hydraulic lift lever (B, figure 2),
raise the mower to full transport position, then shut
off the engine.
6. Use the following procedure to connect the hitch
arms (B, figure 4).
A. Place the mower height control lever (A, figure 2) in
the second notch from high cut position. This
should align the hitch.
B. Use your right hand to apply pressure on the
mower height control quadrant brace in order to
maneuver mower hitch arm(B, figure 4) into the
tractor hitch (A, figure 4). When aligned, use your
left hand to insert pins through mower hitch arms
and tractor hitch. Insert pins so the hole is vertical
to aid in hairpin clip installation. Install hairpin clips
in both pins.
NOTE: Align holes by applying rearward pressure on the
mower height control lever.
