The windrower float springs are NOT used to level the header.
CAUTION
To prevent accidental movement of windrower, return ground speed lever (GSL) to Park, center steering
wheel to lock, shut off engine, and remove key.
IMPORTANT:
Always check the float with the header set in working position (with the header fully lowered to the ground and the
header angle set to the desired cutting height per crop type and conditions).
To check/adjust the float, follow these steps:
1. Start the engine, and lower the header to the ground.
2. Using the header tilt switches on the in-cab controls, set the header center-link to the mid-range position
(5.0 on the cab display module). Refer to your windrower operator
’
s manual for detailed instructions.
3. Lower the header fully with the lift cylinders fully retracted.
4. Set left and right float fine adjustments to mid-range position (5.0 on the cab display module). Refer to your
windrower operator
’
s manual for detailed instructions.
5. Shut down the engine and remove the key.
6. Check float by grasping the lean bar and lifting. Lifting force should be 335
–
380 N (75
–
85 lbf) and should be
approximately the same at both ends.
