Hydraulic Hook-up
!
DANGER
Hydraulic fluid under high pressure can penetrate skin. 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 hydraulic leaks. If
hydraulic fluid is injected into the skin or eyes, it must be
treated by a doctor familiar with this type of injury within a
few hours or gangrene may result. DO NOT DELAY.
Refer to Figure 1-12 on page 17:
1.
Make sure spring support loop (#14) is securely
fastened to the hitch frame and fastener hardware is
properly tightened.
2.
Route cylinder hose (#13) through spring support
loop (#14) and connect to tractor remote outlet. Do
set tractor control lever in float position.
3.
Check driveline for adequate clearance under all
ranges of cutter height.
a. With driveline shaft attached to the tractor, 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 1-11 on page 17
for correct drawbar dimensions.
4.
Cycle hydraulic system by extending and retracting
lift cylinder several times. It may be necessary to
purge the hydraulic system of trapped air if operation
is sluggish. See “Purge Hydraulic System” below.
Purge Hydraulic System
!
DANGER
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
tractor hydraulic system.
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 and retract hydraulic cylinder to purge
trapped air from the hydraulic system.
4.
Lower cutter down until deck skid shoes are 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.
5.
After all air is purged from the hydraulic system and
all hydraulic pressure is relieved, retighten hose
fitting at the hydraulic cylinder.
Assembly of Optional Guards
!
DANGER
Rotary Cutters have the ability to discharge objects at high
speeds; therefore, the use of front and rear safety guards is
strongly recommended when cutting along highways or in
areas where people may be present.
Front Rubber Guard
Refer to Figure 1-13:
1.
Install Front Rubber Guards (#1 & #2) as shown with
3/8"-16 x 1" GR5 carriage bolts (#3), and hex whiz
nuts (#4).
2.
Tighten nuts to the correct torque.

Front Single or Double Chain Guard
Refer to Figure 1-14:
1.
Install front chain guards (#1 & #2) as shown with
3/8"-16 x 1" GR5 carriage bolts (#3), and hex whiz
nuts (#4).
2.
Tighten nuts to the correct torque.
