Section 1: Assembly and Set-Up
Shorten Driveline
Refer to Figure 1-8 on page 14:
Be sure to first check driveline collapsed length as
instructed above. If required, shorten driveline as follows:
1. Un-hook 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 and safety chains 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. Continue with
“Check Driveline Maximum Length”
.
Check Driveline Maximum Length
Refer to Figure 1-9:
The driveline maximum allowable length must, when fully
extended, have a minimum overlap of the profile tubes by
not less than 1/3 the free length with both inner and outer
profile tubes being of equal length.
1. If not already completed, apply multi-purpose grease
to inside of outer profile and reassemble driveline.
2. Assemble the two driveline profiles together with just
1/3 overlapping of the profile tubes as shown below.
Once assembled, measure and record the maximum
allowable length for future reference.
Record Maximum Allowable Length here: ________

Outer Shielding has been removed for clarity.
3. Reattach driveline to tractor and gearbox shaft
“Check Driveline Interference”
Check Driveline Interference
1. Start tractor and raise Rotary Tiller just enough to
remove support blocks from under tiller.
2. Slowly engage tractor hydraulic 3-Point control lever
to lower tiller while checking for sufficient drawbar
clearance. Move drawbar ahead, aside or remove if
required.
Refer to Figure 1-10:
!
WARNING
Lifting unit more than 14" above ground with PTO engaged or
engaging PTO with unit higher than 14" above ground can
break the driveline and could cause flying projectiles.
!
WARNING
down while operating. Exceeding this angle with driveline
rotating can break the driveline and cause flying projectiles.
3. With PTO off, raise implement fully up and make the
following checks below. If driveline exceeds any of
the limits listed, set tractor 3-Point lift limiter at a
height that will keep the driveline within its lift limits to
avoid premature driveline breakdown.
•
Tines do not exceed more than 14
"
off the ground.
•
Driveline does not exceed 25
o
up.
•
Driveline does not exceed maximum allowable
length recorded in step 2 under
Maximum PTO Driveline Movement During Operation
