Check Collapsible Length
Figure 1-5
Check Driveline Collapsible Length
Refer to Figure 1-5:
1.
Make sure driveline is installed properly to the mower
gearbox input shaft and tractor PTO shaft before
checking driveline collapsed length. Refer to
“Driveline Hook-up to Gearbox” and “Driveline
Hook-up to Tractor” on page 13.
2.
With driveline level, measure 1" (“B” dimension)
back from universal joint shield to end of outer
driveline shield as shown in Figure 1-5.
a. If measurement is less than 1", shorten driveline.
a. If measurement is 1" or more, skip to “Check
Maximum Allowable Length” on page 14.
Shorten Driveline
Refer to Figure 1-5:
1.
Un-hook safety chains and driveline from tractor
PTO shaft and gearbox shaft.
2.
Raise 3-Point arms until mower gearbox shaft and
tractor PTO shaft are approximately level with each
other.
3.
Support mower deck at this height with support jacks
or support blocks to keep PTO and gearbox shafts
level while shorting the driveline.
4.
Place gear selector in park, set park brake, shut
tractor off and remove switch key.
5.
Pull driveline apart as shown in Figure 1-5.
6.
Attach outer driveline universal joint to tractor PTO
shaft and inner driveline universal joint to mower
gearbox shaft. Pull on each driveline section to be
sure universal joints are properly secured.

IMPORTANT: A driveline that is too long can bottom
out causing structural damage to tractor and mower.
Always check driveline collapsed 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.
7.
Hold driveline sections parallel to each other. The
inner and outer shields on each section should end
approximately 1" short of reaching universal joint
shield on the adjacent section (see “B” dimensions).
8.
If driveline sections are too long, measure 1"
(“B” dimension) back from universal joint shield and
make a mark at this location on the inner and outer
driveline shields.
9.
Cut-off inner driveline shield at measured mark
(“X” dimension). Cut same amount off inner driveline
profile (“X1” dimension).
10. Repeat cut-off procedure (“Y” & “Y1” dimensions) on
the outer driveline section.
b. Remove all burrs and cuttings.
Check Maximum Allowable Length
Figure 1-6
Check Maximum Allowable Length
Refer to Figure 1-6:
Make sure driveline collapsible length is checked first.
See “Check Driveline Collapsible Length” on page 14.
Driveline maximum allowable length, when fully
extended, must have a minimum overlap of profile tubes
by not less than 1/2 the free length with both inner and
outer profile tubes being of equal length. Determine the
maximum allowable length as follows:
1.
Unhook driveline from tractor and Grooming Mower.
Pull outer and inner drivelines apart.
2.
Measure and record “Free Length” of inner and
outer profiles as shown in Figure 1-6.
3.
Move driveline halves together until profile tubes
overlap by 1/2 the “Free Length”. For future
reference, measure and record “Maximum
Allowable Length” as shown in Figure 1-6.
Record Maximum Allowable Length here: ________
4.
Reattach inner driveline yoke to gearbox shaft and
outer driveline yoke to tractor's PTO shaft.
5.
The driveline should now be moved back and forth to
ensure that both ends are secured. Reattach any
end that is loose.
