Stabilizer Wheel Operation
Adjusting Slow Speed Transport Latch
If slow speed transport latch is difficult to engage (A in
figure 4.100), then adjust wheel hang height on rear axel
by loosening jam nut and turning bolt at rear axel swing
joint using a ¾” or 19mm wrench and socket (see E and
D in figure 3.46 below). Retighten jam nut after adjusting.

Please Refer to Maintenance and Servicing Section of Operators Manual
***Important: There should only be one point of contact with the ground
at any time, either the cutterbar, skid shoes or stabilizer wheels****
When cutting on the ground:
All stabilizer wheels should be locked into the
highest notch with wheels completely off the ground.
When cutting off the ground:
Ø
Headers equipped with stabilizer wheel slow speed transport:
Wheels should be adjusted so that the spring is compressed to between 2 and 3 on
the stabilizer wheel compression gauge (see figure 1). Depending on header
configuration, it might be necessary to adjust LH and RH wheels to different notches
to achieve this proper compression and level cut height.
Ø
Headers equipped with the stabilizer wheels only (non transport):
Operate with springs compressed as shown in figure 2. Total spring compression
should be 11.6 – 13.6 inches (295-345 mm). It might be necessary to adjust LH and
RH wheels to different notches to achieve proper compression and level cut height.
Auto header height control when cutting off the ground
:
To operate with
AHHC when cutting off the ground, it might be necessary to lighten float or to add
slightly more compression to stabilizer wheel springs so that the header will float
upward off of adapter to sense terrain. Ensure that float is unlocked and properly
adjusted (see page 20), do not over compress springs as this may result in hazard or
damage to the shock and spring assembly. See page 14 for setting of AHHC.
