Driveline Hanger Adjustment
Refer to Figure 1-24:
1. Move tractor control lever to extend hydraulic lift
cylinder (#1) until pressure against stroke control
spacers (#2) is removed.
2. Without relieving hydraulic pressure, Shut tractor
down properly before dismounting. Refer to
WARNING
!
To avoid 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. Remove stroke control flip spacers (#2) from
hydraulic lift cylinder (#1) by spreading them apart at
break line.
4. Start tractor and lower cutter until front skids are
resting on the ground or on solid (non-concrete)
support blocks.
5. Shut tractor down properly before dismounting.
6. Replace stroke control flip spacers (#2) as needed to
support wheels at this position.
Refer to Figure 1-25:
7. With driveline attached to tractor, rotate driveline
hanger (#1) up as shown.
8. Loosen nuts securing carriage bolts (#3) and adjust
driveline hanger (#1) up until there is a small gap
between driveline (#5) and hanger (#1).
9. If driveline hanger (#1) is adjusted fully up and needs
to adjust higher, remove carriage bolts (#3) and
reattach hanger to the upper two square holes (#2)
with existing flat washers, lock washers, hex nuts,
and carriage bolts (#3). Continue to adjust hanger to
underside of driveline.
10. Draw nuts securing carriage bolts (#3) up snug and
rotate driveline hanger (#1) down. If hanger makes
contact with driveline (#5), readjust hanger down
until it misses the driveline.
11. Tighten 3/8"-16 GR5 bolts (#3) to the correct torque.
12. Rotate driveline hanger (#1) down.
Driveline Clearance Check
Check driveline for adequate clearance under all ranges
of cutter height.
1. With driveline shaft attached to the tractor and all
stroke control spacers (#6) removed from hydraulic
cylinder (#4), slowly raise and lower cutter to its
upper and lower limits while observing clearances
between hitch and driveline. Adjust tractor drawbar
IMPORTANT:
Always rotate driveline hanger down
before moving cutter to prevent damage to driveline.
height and/or length if driveline interferes. See
on page 13: for correct drawbar
dimensions.
2. It may be necessary to purge lift cylinder, wing
cylinder, and hydraulic hoses of trapped air if
operation is sluggish. Cycle cylinders back and forth
several times to purge air from them. For additional
