5.5 Connecting the Mower-Pull Type
1. Make sure the tractor is equipped with the
correct PTO shaft and the drawbar is extended
14” from the end of the PTO shaft to the hitch
point.
2. Block the mower wheels in place and use the
attached parking jack to raise or lower the
tongue clevis to the height of the tractor
drawbar. The parking jack can be rotated 15
degrees in each direction to obtain a near
vertical position. Note: Always place jack foot
on firm surface or place board under jack for
support.
3. Board the tractor and start the engine. Back the
tractor to the mower aligning the drawbar hitch
hole with the mower hitch clevis. Turn off the
tractor engine, set the parking brake, place the
tractor in park, and dismount.
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 3/4” x 4-1/2” grade 5 or 8 bolt (3) through
clevis and drawbar and retain in position with a
1” locknut (4). The bolt and locknut should be
tightened securely to support the tongue
properly without springing or breaking the
clevis. Never attach mower to the tractor with a
pin not having a nut..
5. Securely attach mower safety chain to 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 main frame.
5.4 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.
