Driveline Installation
If the Grooming Mower is to be used on more than one
tractor, an additional driveline may be required;
especially if a quick hitch is used.
!
WARNING
Damaged drivelines can cause serious injury or death.
!
CAUTION
Tractor PTO shield and all Grooming Mower guards must be
in place at all times during operation!
!

will increase the strain on the tractor’s PTO shaft and can
damage the PTO shaft and mower driveline.
Maximum PTO driveline Movement During Operation

Refer to Figure 1-4
1.
Start tractor and slowly engage tractor’s hydraulic
3-point to lift the lower arms until the Grooming
IMPORTANT: Avoid premature driveline
breakdown. A driveline that is operating must not
exceed an angle of 25 degrees up or down while
operating the 3-point lift. See Figure 1-4 below.

IMPORTANT: Some tractors are equipped with
multi-speed PTO ranges. Be certain your tractor ‘s
PTO is set for 540 rpm.
IMPORTANT: The PTO driveline may be too long for
some tractors. If the Grooming Mower is used on
more than one tractor, an additional PTO driveline
may be required.
IMPORTANT: Aligning the tractor’s PTO shaft level
with the Grooming Mower’s PTO shaft is necessary
when checking to see if the driveline will fit correctly
between tractor and Grooming Mower.
Mower’s driveline shaft is approximately level with
tractor's PTO shaft.
2. Slide outer yoke end of driveline over the tractor's
PTO shaft and secure with the locking collar. Skip to
step 4 if driveline fits between tractor and Grooming
Mower.
3. The driveline will require shortening if it is too long to
fit between the tractor and Grooming Mower.
Shorten driveline as follows:
a. Raise 3-point lower arms until Grooming Mower
and tractor PTO shafts are approximately level
with each other. Securely block Grooming Mower
frame in this position. Set tractor in park, shut
tractor engine off, set park brake and remove
switch key.
b. Pull driveline apart into two sections as shown in
Figure 1-5. Attach the outer driveline universal
joint to the tractor PTO shaft and inner driveline
universal joint to the Grooming Mower gearbox
shaft. Pull on each driveline section to be sure the
universal joints are secured to the shafts.
c. Hold the driveline sections parallel to each other
to determine if they are too long. The inner and
outer shields on each section should end
approximately 1" short of reaching the universal
joint shield on the adjacent section (see “B”
dimension). If they are too long, measure 1" (“B”
dimension) back from the universal joint shield
and make a mark at this location on the inner and
outer driveline shields.
d. Cut off the inner shield at the mark (“X”
dimension). Cut the same amount off the inner
shaft (“X1” dimension). Repeat cut off procedure
(“Y” & “Y1” dimensions) to the outer driveline half.
e. Remove all burrs and cuttings.
f. Apply multi-purpose grease to the inside of the
outer shaft and reassemble the driveline.
g. Attach inner driveline yoke end to the Grooming
Mower gearbox input shaft.
h. Attach outer driveline yoke end to the tractor's
PTO shaft.
