OPERATION
6.1 Connecting the Mower Tongue to the Tractor
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 clevis to be level
and parallel with the tractor drawbar using the
control rod connecting the mower tongue
clevis 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. Insert a 1” diameter
grade 5 or 8 bolt (2) through clevis and
drawbar and retain in position with a 1”
locknut (3). 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. Make sure the chain is attached
to a secure location on the tractor and not to an intermediate support. 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. When not in use, store the
safety chain to protect it from mud or standing water by wrapping the chain around the tongue. Replace the
safety chain if one or more links or end fittings are broken, stretched or otherwise damaged or deformed.
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)
