Hydraulic Hook-Up (Pull-Type)
WARNING
!
To avoid serious injury or death:
Hydraulic fluid under high pressure will penetrate the skin or
eyes causing a serious injury. Wear protective gloves and
safety glasses or goggles when working with hydraulic
systems. Use a piece of cardboard or wood rather than hands
when searching for leaks. If an accident occurs, seek
immediate emergency medical care or gangrene may result.
Refer to Figure 1-27 on page 34:
1. Route hydraulic hose (#8) through spring hose
loop (#7) and attach to tractor hydraulic outlet.
2. If cutter is provided with a CV driveline, route
hydraulic hose beneath trunnion support (#3).
3. Check driveline for adequate clearance under all
ranges of cutter height.
a. With driveline attached to tractor and cutter,
slowly raise and lower cutter to its upper and
lower limits while observing clearances between
hitch and driveline.
b. Adjust tractor drawbar height and/or length if
driveline interferes. See Figure 1-1 on page 12 for
correct drawbar dimensions.
4. Cycle hydraulic system by extending and retracting
lift cylinder several times. It may be necessary to
purge hydraulic system of trapped air if operation is

Purge Hydraulic System (Pull-Type)
DANGER
!
To avoid serious injury or death:
Be sure deck is lowered to the ground and all hydraulic
pressure is relieved before disconnecting or reconnecting
hydraulic line and/or fittings between Rotary Cutter and
1. With deck skid shoes resting firmly on the ground,
shut tractor off, and move hydraulic control lever back
and forth to relieve all hydraulic pressure in the
hydraulic system.
2. Loosen hydraulic hose fitting at the hydraulic cylinder
slightly to allow air and fluid to escape.
3. Restart tractor and slowly activate tractor control
lever to extend hydraulic cylinder to purge trapped air
from the hydraulic system.
4. After all air is purged from the hydraulic system and
all hydraulic pressure is relieved, tighten hose fitting
at the hydraulic cylinder.
LP Performance Hitch Hook-Up
Figure 1-28
14.
Refer to Figure 1-28:
Performance Hitch, remove hairpin cotter (#5) and
hitch pin (#6) from clevis (#4).
15. Lower park jack (#10) until cutter tongue (#1) is
supported by tractor drawbar.
16. Fully retract park jack (#10), remove ball detent
pin (#11), and store park jack attached to storage
holder (#13) on the cutter deck with ball detent pin
securing the park jack.
17. If needed, collapse driveline by pushing tractor end
of driveline toward the cutter gearbox.
18. Pull back on yoke lock collar (#9) and slide yoke over
the tractor’s power take-off shaft.
19. Release lock collar (#9) and continue to push yoke
end of driveline onto the tractor power take-off shaft
until lock collar snaps in place.
20. Driveline (#5) should be moved back and forth to
ensure both ends are secured to tractor and gearbox
shafts. Reattach any end that is loose.
Safety Chain Hook-Up For Pull-Type
Refer to Figure 1-27 on page 34:
When towing implements on public roads, use safety
chain (#12) with tensile strength equal to or greater than
gross weight of implement being towed. This will control
the implement in the event the hitch pin is lost.
After attaching safety chain (#12) to the tractor, make a
trial run by driving tractor to the right and to the left for a
short distance to check safety chain adjustment. If
necessary, re-adjust chain length to eliminate a tight or
loose chain. Make sure chain hook is securely locked in
place.
IMPORTANT:
Always store park jack on the deck
