Maximum PTO driveline Movement During Operation
Figure 2-3
Shortening the PTO Shafts
Figure 2-4
Checking Driveline Minimum Length
Refer to Figure 2-4:
1.
Start tractor and slowly engage 3-point to move
lower arms until the gearbox shaft is approximately
level with tractor's PTO shaft.
2.
Slide inner yoke of the driveline over the gearbox
shaft and secure with locking collar.
3.
Slide outer yoke of driveline over the tractor PTO
shaft and secure with locking collar. Skip to step 5 on
page 12 if driveline fits between tractor and gearbox.
IMPORTANT: Some tractors are equipped with
multi-speed PTO ranges. Be certain your tractor ‘s
PTO is set for 540 rpm.
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 2-3 below.

IMPORTANT: Always check driveline minimum
length during initial setup, when connecting to a
different tractor and when alternating between using
a quick hitch and a standard 3-point hitch. More than
one driveline may be required to fit all applications.
IMPORTANT: It is necessary to aligning the tractor’s
PTO shaft level with the gearbox shaft when
checking driveline minimum length. Too long a
driveline can damage tractor, gearbox and driveline.

4.
The driveline will require shortening if it is too long to
fit between tractor and gearbox. Shorten driveline as
follows:
a. Raise or lower 3-point lower arms until gearbox
and tractor PTO shafts are approximately level
with each other. Securely block mower frame in
this position.
b. Set tractor in park, shut tractor engine off, set park
brake and remove switch key.
c. Pull driveline apart into two sections as shown in
Figure 2-4. Attach outer driveline universal joint to
the tractor PTO shaft. Attach inner driveline
universal joint to the gearbox shaft. Pull on each
driveline section to be sure universal joints are
secured to the shafts.
d. Hold 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.
e. Cut off inner shield at mark (“X” dimension). Cut
same amount off inner shaft (“X1” dimension).
Repeat cut off procedure (“Y” & “Y1” dimensions)
to cut outer driveline half.
f. Remove all burrs and cuttings.
5.
Apply multi-purpose grease to the inside of the outer
driveline shaft and reassemble the two shafts.
6.
Attach inner driveline yoke to the gearbox shaft.
7.
Attach outer driveline yoke to the tractor's PTO shaft.
8.
The driveline should now be moved back and forth to
insure that both ends are secured to the tractor and
gearbox PTO shafts. Reattach any end that is loose.
9.
Hook one of the driveline safety chains in a hole on
the outer driveline yoke shield and the opposite end
to the tractor to restrict outer shield rotation.
10. Hook the second driveline safety chain in a hole on
the inner driveline yoke shield and the opposite end
to the mower to restrict inner shield rotation.
11. Start tractor and raise the Grooming Mower just
enough to remove blocks used to support the mower
frame in step 4a above.
12. Slowly engage the tractor’s hydraulic 3-point to lower
the mower. Check for sufficient drawbar clearance.
Move drawbar ahead, aside or remove if required.
IMPORTANT: Two small chains are supplied with
the driveline. These chains must be attached to
outer and inner driveline yoke shields and to the
cutter deck and tractor to restrict driveline shields
from rotating.
