OPERATION
ATTACHING WINDROWER TO TRACTOR
CAUTION: Shut off tractor, engage
parking brake and remove key before
working around hitch.
CAUTION: Never attach windrower to
tractor rear axle or three-point hitch
arms.
1. Using the jack, raise windrower tongue to clear
the hitch pin in drawbar extension. Position
tractor to align ball joint on tongue with hitch pin
and lower tongue. Secure with lock pin (A).
2. Route hitch chain from windrower through
chain support (B), around drawbar support and
lock hook (C) on chain.
IMPORTANT: Adjust chain length to remove all
slack except what is needed for turns.
3. Remove weight from jack. Pull pin securing
jack and move to storage position (D) on top of
frame tube.
4. NOTE: Pump attachment is easier if hitch is
angled to tractor, not straight on.
Slide the hydraulic pump assembly onto the
PTO shaft of the tractor. Adjust the torque arm
(E) so that it rests on the right side of the
drawbar.
IMPORTANT:
• Pump outlets must remain vertical. Loop the
torque arm chain (F) around the drawbar and
lock the chain in keyhole slot in torque arm
mounting plate.
•
To prevent hose damage, route hoses through
guide (G) to provide proper hose arc as shown.
•
Full engagement of PTO shaft into pump is
required to prevent damage to pump spline.
Pump should slide 2-1/2" (64 mm) onto shaft.
•
The pump must never be keyed or fastened to
the PTO shaft. If the drawbar pin should
become disengaged, the pump must be free to
slip off.
