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.
7. SETTING THE MOWER
After the mower is attached to the tractor’s 3-point hitch, but before the universal slip joint is installed, and with
the mower on the ground, adjust the top link of the hitch to make the mower gearbox input shaft parallel to the
tractor PTO shaft. This relationship provides optimum operation of the universal joints in the driveline. A
driveline that is not parallel to the PTO will result in vibration due to the characteristic of a universal joint that
results in the output end speeding up and slowing down twice each revolution of the universal jointed shaft.
Adjust the top link whenever the cutting height is changed.
Properly setting the cutting height is essential for efficient and safe operation. A properly set mower will make
a more uniform cut, distribute clippings more evenly, require minimal tractor work, and follow the contour of
uneven terrain.
NOTE: Avoid very low cutting heights, striking the ground with the blades gives the most damaging shock
loads and will cause damage to the mower and drive. Blades contacting the ground may cause objects to be
thrown out from under the mower deck. Always avoid operating the mower at a height which causes the
blades to contact the ground. OPS-F-0071
Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked up
to prevent sudden or inadvertent falling which could cause serious
injury or even death.
