Shorten Driveline Length
Refer to Figure 1-5 on page 14:
1. Unhook outer 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 shafts.
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”
below.
Check Driveline Maximum Length
Refer to Figure 1-6:
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 Wood Chipper.
Pull outer and inner drivelines apart.
2. Measure and record “Free Length” of inner and
outer profiles as shown in Figure 1-6.
3. Apply multi-purpose grease to the inside of the outer
profile and reassemble the two profiles.
4. 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: ________
5. Reattach inner driveline yoke to gearbox shaft and
outer driveline yoke to tractor's PTO shaft.
6. The driveline should now be moved back and forth to
ensure that both ends are secured. Reattach any end
that is loose.

WARNING
Do not operate in raised position. Lifting the Wood Chipper
too high with driveline engaged can damage the driveline and
cause flying projectiles causing serious bodily injury or death.
Refer to Figure 1-7:
1. Start tractor and slowly engage tractor hydraulic
3-Point control lever to raise and lower chipper while
checking for sufficient drawbar clearance. Move
drawbar ahead, aside, or remove if required.
2. Raise and lower implement to find maximum
extended driveline length. Check to make certain
driveline does not exceed maximum allowable length
and 25
o
up or down and maximum allowable length
recorded in step 4 under “Check Driveline
Maximum Length” on this page.
3. If needed, set tractor 3-Point lift height to keep
driveline from exceeding the maximum allowable
length and 25
o
up.

Outer Shielding has been removed for clarity.
IMPORTANT: To avoid premature driveline damage,
a driveline that is operating must not exceed an
angle of 25 degrees up or down.
