5.1 Connecting the Mower-Lift Type
1. Make sure the tractor is equipped with the
correct PTO shaft. Change shafts if needed.
2. Shorten or remove the tractor drawbar to avoid
interference when raising and lowering the
mower.
3. Board the tractor and start the engine. Position
the tractor to the mower with the 3-point lift
arms positioned at the same height and to the
outside of the mower hitch pins. Note: Set the
3-point lift control to "Position Control" so that
the lift arms maintain a constant height when
attaching the mower. See the tractor Operator's
Manual for correct settings when attaching 3-
point equipment.
4. Turn off the tractor engine and dismount.
5. One lift arm at a time, align arm end hole
between the set of A-frame lift lugs. Insert hitch
pin through the lug and arm holes and insert
retaining pin into hitch pin.
6. Walk around to opposite side and repeat
procedure for remaining lift arm and hitch pin.
7. Extend or retract 3-point top link to align its end
hole with the holes of the mower's top link.
Insert the top link hitch pin and insert retaining
pin into hitch pin.
8. Adjust any lower link check chains, guide
blocks, or sway blocks to prevent the mower
from swaying side to side and possible contact
with tractor rear tires.
