1. Ensure the tractor is equipped with the correct PTO
shaft and the drawbar is set at the correct length.
2. Using the parking jack, position the tongue clevis
to the height of the tractor drawbar. Adjust the
mower tongue to be level and parallel with the
tractor drawbar using the control rod connecting
the mower tongue to the deck.
3. Board the tractor and start the engine. Back the
tractor to the mower aligning the drawbar hitch hole
with the mower tongue clevis. Turn off the tractor
engine, place the tractor in park, and set the parking
brake before dismounting.
4. To attach the mower, place two 1” flatwashers (1)
positioned under top lip of tongue clevis and to the
top of drawbar. Add additional 1” flatwashers (2)
between the bottom of drawbar and bottom lip of
clevis to fill open space. Insert a 1” diameter grade
5 or 8 bolt (3) through clevis and drawbar and retain
in position with a 1” locknut (4). Tighten the locknut
securely but do overtighten which could spring or
break the clevis. NEVER attach mower to the
tractor with a pin not having a nut.
5. Securely attach the mower safety chain to the
tractor drawbar or drawbar support frame.
6. Lower the jack until the tongue is completely
supported by the drawbar. Remove jack from the
tongue and place on storage bracket of mower.

Safety Tow Chain
If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the gross
weight of the mower must be connected between the tractor and mower. This will help control the implement in the
event the tongue becomes disconnected from the drawbar. After connecting both ends of the safety chain, drive
the tractor to the right and left to check for proper chain length. Adjust length as necessary and allow only enough
slack in the chain to make a maximum turn in both directions.
5. CONNECTING THE MOWER TO THE TRACTOR
Use extreme caution when connecting the mower to the tractor. The mower should be securely resting at ground
level or on blocks. Place a block in front of and behind the center section wheels to prevent the mower from
moving. Keep hands and feet out from under the mower and clear of pinch points between the tractor and mower.
DANGER!
Always shut the Tractor completely down, place the transmission in park, and set the parking
brake before you or anyone else attempts to connect or disconnect the Implement and
Tractor hitches. (S3PT-15)
