A. Insure that all bolts and hitch pins on 3-point hitch are tightened. Hitches need no further
adjustment.
B. Attach rotary mower to tractor 3-point hitch per tractor operator's manual. Do not attach
driveline at this time. (figure 2-1)
C. Raise 3-point hitch until front of mower is approximately 1 - 2 inches (25-51 mm) lower
than rear for standard cut or until front of mower is 1 inch (35 mm) higher than rear for
extra shredding. Shut down tractor. Securely block mower in position. For further
explanation of rotary mower adjustment, see paragraph 3-2.
NOTE:
Due to the many variations in tractor/implement hitch points and corresponding differences in
distances between tractor PTO shafts and implement input shafts, drivelines may need to be
shortened as described in the following steps:
D. Raise and lower rotary mower to determine position with shortest distance between the
tractor PTO shaft and gearbox input shaft. Shut down tractor leaving cutter in position of
shortest distance. Securely block rotary mower in position.
E. Pull driveline apart. Attach outer (female) section to tractor PTO shaft. Pull on driveline
section to be sure that yoke locks into place.
F. Hold driveline sections parallel to each other to determine if too long. Each section should
end approximately 3 inches (76 mm) short of reaching universal joint shield on opposite
section. If too long, measure 3 inches (76 mm) back from universal joint shield and mark on
opposite section. (figure 2-2). Do this for both sections.
G. Raise and lower rotary mower to determine position with greatest distance between PTO
shaft and gearbox input shaft. Shut down tractor leaving rotary mower in position of
greatest distance. Securely block rotary mower in position.
