Pull-Type Leveling & Cutting Height
See page 27 for
“3-Point Leveling & Cutting Height”
There are two primary adjustments that should be made
prior to actual field operations:
•
Deck Leveling From Front to Back
•
Proper adjustment of each of these items will provide for
higher efficiency, improved cutting performance, and
longer blade life. The following tools will be needed:
•
Pliable tape measure
•
Spirit or carpenter’s level
•
Open end or hex end wrench or socket set
•
Protective gloves
WARNING
!
To avoid serious injury or death:
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
Deck Leveling
Figure 3-1
Deck Leveling From Front to Back
Refer to Figure 3-1:
1. Hook cutter to tractor. Refer to page 17 or 19.
2. Locate tractor with cutter on a flat, level surface.
3. Use tractor’s hydraulics to adjust deck height above
ground level 2 to 3 inches.
4. Place a spirit level (#3) or other suitable leveling
device on either of the main deck channels.
5. If cutter deck is not slightly lower at the front than at
the back, then loosen jam nuts (#1) on both sides
and rotate leveling rod adjusting nuts (#2) until deck
is slightly lower by an equal amounts on both sides.
6. Be sure that the right and left leveling rods are
equally tight and then re-tighten jam nuts (#1).

NOTE:
The unit cuts most efficiently if the front of
the cutter is slightly lower than the back.
Lengthening leveling rods with adjusting nuts (#2)
lowers the front of the cutter.
Pull-Type Cutting Height
Refer to Figure 3-2:
Lift mechanism for pull-type units can be equipped with
either a ratchet jack (#1) or hydraulic cylinder (#2). Adjust
lifting mechanism if cutting height is too high or too low.
Ratchet Jack Instructions
The deck can be raised or lowered by setting the ratchet
mechanism on the ratchet jack (#1) and then pumping
the jack handle to raise or lower the cutter to desired
cutting height.
Hydraulic cylinder Instructions
Stroke control spacers (#3) are included with the
hydraulic set-up. They consist of cast steel halves with
spring clips to hold the two halves together.
1. Extend the hydraulic cylinder to free up space on the
cylinder rod for installing and removing spacers. Add
or remove spacers as needed.
2. Retract hydraulic cylinder and re-measure to verify if
cutting height is suitable.
3. Store stroke control spacers on hydraulic hose (#4)
near the hydraulic cylinder.
