b.
Shorten inner and outer guard tubes equally.
c.
Shorten inner and outer sliding profiles by the
same length as the guard tubes.
d.
Proper overlap is a minimum of one-half the
length of each tube, with both tubes being of equal
length.
e.
Round off all sharp edges and remove burrs.
Grease sliding profiles.
9.
Route cylinder hoses through hose support loop and
connect to tractor remote outlets. Refer to "Hydraulic
Plumbing" on page 9 for proper hookup. If the tractor
being used does not have three pair of supply outlets,
an optional control valve kit is available from your
dealer.
10. Cycle the hydraulic system by raising and lowering the
center deck cylinder and the wing fold cylinders. If op-
eration is sluggish, it may be necessary to purge the
system of trapped air.
!
DANGER!
Hydraulic fluid under pressure can penetrate skin. Wear protec-
tive gloves and safety glasses or goggles when working with hy-
draulic systems. Use a piece of cardboard or wood rather than
hands when searching for hydraulic leaks. If hydraulic fluid is
injected into the skin, it must be surgically removed within a few
hours by a doctor or gangrene may result.
a.
With the wings lowered to the ground, loosen the
hydraulic hose fitting at each wing cylinder slightly
to allow fluid to escape.
b.
Slowly activate the tractor control valve to purge
any trapped air from the system.
c.
Tighten each fitting.
The optional center deck lift cylinder is purged in the same
manner. The cutter should be lowered to the ground or the
cylinder fully retracted before loosening the hose fitting (as
described above).
11. The PTO Constant Velocity shaft or conventional PTO
(if used) should be checked for adequate clearance
under all ranges of cutter height depending on the
tractor being used. With the PTO shaft attached to the
tractor, slowly raise and lower the cutter to upper and
lower limits while observing clearance distance be-
tween hitch and PTO shaft. If an interference condi-
tion exists, it may be necessary to modify the drawbar
height/length of the tractor.
