4. 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.
5. Remove driveline from tractor and gearbox shafts.
6. 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).
7.
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).
8. Remove all burrs and cuttings.
9. Check driveline extended length next.
Check Driveline Extended Length
Make sure driveline collapsible length is acceptable. If
needed, refer to
“Check Driveline Collapsible Length”
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.
Apply multi-purpose grease to the inside of the outer
shaft and reassemble the driveline.
2. Assemble driveline profiles together with 1/3
overlapping of inner and outer profile tubes. Once
assembled, measure and record the maximum
allowable length shown below for future reference.

3. Attach inner driveline yoke to the mower gearbox
shaft. Attach outer driveline yoke to the tractor's
power take-off shaft.
4. Move yoke ends of driveline back and forth to ensure
they are secured to the tractor and mower shafts.
Reattach any end that is loose.
5. Start tractor and raise Flail Mower just enough to
remove support jacks or blocks.

Outer shielding has been removed for clarity.
6. Slowly engage tractor hydraulic 3-point control lever
to lower Flail Mower. Check for sufficient drawbar
clearance. Move drawbar ahead or remove if
required.
7.
Raise and lower implement to find maximum
extended driveline length. Check to make certain that
the driveline overall length does not exceed the
maximum recorded length in step 2.
8. If needed, set tractor 3-point lift height to keep
driveline from exceeding maximum allowable length.

1.
Slowly engage tractor hydraulic 3-point control lever
to lower mower while checking for sufficient drawbar
clearance. Move drawbar ahead or remove if
required.
2. Raise and lower implement to find maximum
extended driveline length. Check to make certain the
driveline does not exceed the maximum allowable
length and 25
o
up or down.
3. If needed, set tractor 3-point lift height to keep
driveline from exceeding the maximum allowable
length and 25
o
up.
IMPORTANT:
Avoid premature driveline breakdown.
A driveline that is operating
must not exceed
an
angle of 25
o
up or down while operating 3-point lift.
If needed, set tractor 3-point lift height so that the
driveline does not exceed 25
o
up.
