Pull-Type With Rear Axle
The following instructions are for leveling and setting the
cutting height of a Pull-Type cutter. There are two primary
adjustments that should be made prior to actual field
operations:
•
•
Proper adjustment of each of these items will provide
higher efficiency, improved cutting performance and
longer blade life.
WARNING
!
To avoid serious injury or death:
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
Level Front To Back
1. Having completed
“Tractor Hook-up”
, locate tractor
and cutter on a flat, level surface.
2. Use tractor’s hydraulics to adjust cutter height until
front of skid shoes are 2 to 3 inches off the ground.
Refer to Figure 3-11 on page 47:
3. Place a spirit level (#3) or other suitable leveling
device on one of the main deck channels to check
deck profile. Deck profile should be slightly higher at
the back than at the front.
Refer to Figure 3-9:
4. If cutter deck is not approximately 1" (2.5 cm) lower at
the front than at the back, then loosen jam nuts (#1)
on both sides of the deck and rotate leveling rod
adjusting nuts (#2) equally until deck is slightly
higher at the back.
5. Be sure that the right and left leveling rods are
equally tight and then re-tighten jam nuts (#1).
Cutting Height Adjustment
Refer to Figure 3-11 on page 47:
WARNING
!
To avoid serious injury or death:
Avoid direct contact with cutter blades by wearing a pair of
gloves. Cutter blades have sharp edges and burrs that can
1. With gloves on, carefully rotate blade tips on one side
of the cutter to the position shown in Figure 3-11 on
2. Measure distance from end of blade (cutting tip) to
ground. This distance is the cutting height.
IMPORTANT:
The front blade tip should be slightly
lower than the rear blade tip (about 1" (25 cm) lower)
If not, the cutter is subject to continuous material flow
under it’s deck causing horsepower loss, grass
clumps, blade wear, and frequent blade sharpening.
NOTE:
Lengthening leveling rods with adjusting
nuts (#2) raises the back of the cutter.
