WARNING
!
To avoid serious injury or death:
Refer to (Standard Clevis Hitch Shown) on page 23:
1.
Make sure spring support loop (#14) is securely
fastened to the hitch frame and fastener hardware is
properly tightened.
2.
Route cylinder hose (#9) 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.
Observe clearances between hitch and driveline.
b. Adjust tractor drawbar height and/or length if
driveline interferes. See Figure 1-15 on page 23

Purge Hydraulic System
DANGER
!
To avoid serious injury or death:
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, tighten hose fitting
at the hydraulic cylinder.
