5.4 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 PTO shaft end for a 540 RPM
mower and 16” for a 1000 RPM unit.
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.
7. If using a hydraulic cylinder, connect hydraulic
hose ends into tractor hydraulic ports.
8. If the mower has been attached to a 3-point
hitch drawbar, adjust any tractor equipped lower
link check chains, guide blocks, or sway blocks
to prevent the hitch and mower from swaying
side to side. Note: Never raise the 3-point lift
with the mower attached as catastrophic
driveline damage will occur.
