Check Driveline Collapsible Length; Shorten Driveline - Land Pride RTR1550 Operator's Manual

Section 1: Assembly & Set-Up
Refer to Figure 1-4 on page 10:
IMPORTANT: The power take-off shaft and gearbox
input shaft must be aligned and level with each other
when checking driveline minimum length. A driveline
that is too long can damage tractor and implement.
1.
Park tractor and tiller on a level surface. Raise tiller to
align gearbox input shaft level with tractor PTO shaft.
Securely block tiller at this height to keep unit from
lowering while attaching the driveline.
2. Place gear selector in park, shut tractor engine off,
set park brake, and remove switch key.
3. Remove gearbox shaft protector (#9) from end of
gearbox shaft and slide slip clutch end of driveline
(#1) over gearbox input shaft. Secure to gearbox with
driveline yoke locking device.
4. Slide other end of driveline (#1) over tractor PTO
shaft. Secure driveline with yoke locking device.
5. Move driveline yokes back and forth to ensure both
ends are secured to the shafts. Reattach any yoke
that is loose.
NOTE: If driveline is too long to fit between tractor
and tiller, skip to "Shorten Driveline" on this page.

Check Driveline Collapsible Length

Refer to Figure 1-9:
IMPORTANT: A driveline that is too long can bottom
out causing structural damage to tractor and
implement. 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.
1. Make sure driveline is installed properly before
checking driveline collapsed length (Refer to
"Driveline Installation" on page 11).
2. With driveline level, measure ("B" dimension) back
from universal joint shield to end of outer driveline
shield as shown in Figure 1-9.
a. If measurement is less than 1", shorten driveline.
b. If measurement is 1" or more, skip to "Check
Driveline Maximum Length" on page 13.

Shorten Driveline

Refer to Figure 1-9:
Be sure to first check driveline collapsed length as
instructed above. If required, shorten driveline as follows:
1. Unhook driveline from tractor PTO shaft and pull
outer and inner drivelines apart.
2. Reattach outer driveline to tractor PTO shaft. Pull on
inner and outer drivelines to be sure universal joints
are properly secured.
3. Hold inner and outer drivelines parallel to each other:
a. Measure 1" ("B" dimension) back from outer
driveline universal joint shield and make a mark at
this location on the inner driveline shield.
b. Measure 1" ("B" dimension) back from the inner
driveline universal joint shield and make a mark at
this location on the outer driveline shield.
4. Remove driveline from tractor and gearbox.
5. Measure from end of inner shield to scribed mark
("X" dimension). Cut off inner shield at the mark. Cut
same amount off the inner shaft ("X1" dimension).
6. Measure from end of outer shield to scribed mark
("Y" dimension). Cut off outer shield at the mark. Cut
same amount off the outer shaft ("Y1" dimension).
7. Remove all burrs and cuttings.
8. Apply multi-purpose grease to the inside of the outer
shaft and reassemble driveline.
9. Attach driveline to tiller gearbox input shaft and
tractor PTO shaft. Refer to "Driveline Installation"
on page 11 for detailed instructions.
10. Continue with "Check Driveline Maximum Length"
on page 13.
