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.
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 properly before dismounting according to
“Tractor Shutdown Procedure” on page 15.
3. Move stroke control flip spacers (#2) from closed
position to their open position.
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 properly before dismounting.
6. Close stroke control flip spacers (#2) as needed to
support wheels at this position.
Refer to Figure 1-25:
7. With driveline (#2) attached to tractor, rotate driveline
hanger (#1) up as shown.
8. If gap between driveline (#2) and driveline
hanger (#1) is too wide to safely rest driveline on
hanger when not attached to tractor, loosen all four
hex nuts (#6) on carriage bolts (#3) and adjust
driveline hanger (#1) up until there is a small gap
between driveline (#2) and driveline hanger (#1).
9. If gap between driveline (#2) and driveline
hanger (#1) is still too wide, adjust hanger by
removing all four carriage bolts (#3), and all its
corresponding hardware.
10. With hardware removed, adjust driveline hanger (#1)
to achieve appropriate gap distance from underside
of driveline, and reinsert all four carriage bolts (#3)
into appropriate square holes (#7).
11. Secure all four carriage bolts (#3) with recently
removed flat washers (#4), lock washers (#5) and hex
nuts (#6). Thread hex nuts so they are snug against
lock washer, but do not tighten at this time.
12. Pivot driveline hanger (#1) up and down to make sure
driveline hanger does not make contact with
driveline (#2). If needed, readjust hanger down until it
misses the driveline (#2).
13. Tighten all four 3/8"-16 GR5 carriage bolts (#3) to the
correct torque. Refer to the “Torque Values Chart for
Common Bolt Sizes”
on page 65.
14. When adjustments are complete, rotate driveline
hanger (#1) down.
IMPORTANT:
Always rotate driveline hanger down
before moving cutter to prevent damage to driveline.

Driveline Clearance Check
Refer to Figure 1-26 on page 25:
Check driveline for adequate clearance under all ranges
of cutter height.
1. With driveline attached to the tractor and all stroke
control flip spacers (#6) in open position, slowly raise
and lower cutter to its upper and lower limits while
observing clearances between hitch and driveline.
2. Adjust tractor drawbar height and/or length if
driveline interferes. See Figure 1-1 on page 13 for
correct drawbar dimensions.
3. 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
details, see “Purge Hydraulic System” on page 25.
