Driveline Support Adjustment
Refer to Figure 1-27:
1. Move tractor control lever to extend hydraulic lift
cylinder (#1) until pressure against flip spacers (#2)
has been eliminated.
2. Without relieving hydraulic pressure, shut tractor
down before dismounting according to
WARNING
!
To prevent serious injury or death:
Stay clear from underneath the cutter and directly behind
transport tires. The cutter could fall suddenly causing the
decks to lower and tires to roll back.
3. Move flip spacers (#2) from closed position to their
open position as shown.
4. Start tractor and lower cutter until front skid shoes
are resting on the ground or on solid, non-concrete
support blocks.
5. Shut tractor down before dismounting according to
6. Close flip spacers (#2) as needed to support wheels
at this position.
Refer to Figure 1-28:
7.
With driveline (#2) attached to the tractor, rotate
driveline support (#1) up to check clearance between
the driveline and driveline support.
8. Adjust height of driveline support (#1) if it contacts
driveline (#2) or if there is too much gap between the
driveline and driveline support.
a. Loosen all four nuts (#6) and adjust driveline
support (#1) up or down until there is a small gap
under driveline (#2) while rotating the support up
and down. If this gap is acceptable, skip to step f.
Otherwise, continue with step b.
b. If the gap can not be adjusted correctly, remove
nuts (#6), lock washers (#5), flat washers (#4),
and carriage bolts (#3).
c. Adjust driveline support (#1) up or down as
needed to achieve the appropriate gap. Install
carriage bolts (#3) into the appropriate square
holes (#7).
d. Secure bolts (#7) with flat washers (#4), lock
washers (#5), and nuts (#6). Draw nuts up snug.
Do not tighten nuts at this time.
e. Pivot driveline support (#1) up and down to make
sure there is a small clearance gap between the
support and driveline (#2). If needed, readjust
driveline support until there is a small clearance.
NOTE:
The driveline support must be able to rotate
up and down with minimum clearance between the
driveline and driveline support while the driveline is
connected to the tractor’s power take-off shaft.

f. Tighten all four nuts (#6) to the correct torque for a
3/8"-16 GR5 bolt.
9. When adjustments are complete, rotate driveline
support (#1) down and away from driveline (#2).
Driveline Clearance Check
Check driveline for adequate clearance under all ranges
of cutter height.
1. With driveline attached to the tractor, verify all flip
spacers (#2) in
2. Slowly raise and lower cutter to its upper and lower
limits while observing clearances between the cutter
hitch frame and driveline (#2) in
3. Adjust tractor drawbar height and/or length if
driveline interferes. See
on page 15 for
correct drawbar dimensions.

IMPORTANT:
Always rotate driveline support down
before moving cutter to prevent damage to driveline.
