Stabilizer Wheel Height Adjustments
The stabilizing wheel system in both options is designed to minimize bouncing at the header ends
and may be used to “float” the headers to achieve an even cutting height when cutting above
ground level in cereal grains.
Note: Using the stabilizer wheels when operating with the cutterbar on the ground (i.e. cutting soybeans) is not
recommended. They should be fully raised to prevent contact with the ground.
For Stabilizer Wheels only:
1. Ensure adapter float is properly set.
2. Raise header above desired cutting height using
windrower or combine controls.
3. Support wheel weight by lifting slightly on handle (B) with
one hand.
4. Pull up on handle (A) to release lock.
5. Lift wheel with handle (B) to desired height and engage
support channel into slot (C) in upper support.
6. Push down on handle (A) to lock.
7. Lower header to desired cutting height using combine or
windrower controls, and check spring length as shown. Readjust
wheels as required to achieve proper range. Overall spring length
should be 12.6 in (320 mm).
Note: Continuous operation with excessive spring compression (spring length shorter
than 11.6 in/295 mm) can result in damage to the suspension system.
For Transport/Stabilizer Wheels only:
1. Ensure adapter float is properly set.
2. Raise header above desired cutting height using
windrower or combine controls.
3. Disengage latch (A) and lift right wheel out of hook and
place on ground as shown. This reduces weight of
assembly and makes adjusting wheel position easier.
4. Support wheel weight by lifting slightly with one hand.
Pull up on handle (B) to release lock.
5. Lift wheel to desired height and engage support channel
into slot (C) in upper support.
6. Push down on handle (B) to lock.
7. Lift right hand wheel back into field position and ensure
latch (A) is engaged.
8. Lower header to desired cutting height using combine or windrower
controls, and check spring compression as shown. Readjust wheels
as required to achieve proper range. Load indicator should be
between 2 and 3.
Note: Continuous operation with excessive spring compression (load indicator reading
greater than #4) can result in damage to the suspension system.
