215676 427 Revision A
Adjusting Header Drop Rate
The header should lower gradually when the LOWER HEADER switch is pressed. Lowering the header from the fully raised
to the fully lowered position should take 3–4 seconds.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key from the ignition before leaving the operator’s seat for any reason.
IMPORTANT:
The drop rate should NOT be less than 3–4 seconds; damage to the header or windrower may result if the drop rate is
higher than this.
NOTE:
If the drop rate is too low (that is, if it requires more than 30 seconds for the header to move from the fully raised to the
fully lowered position), the windrower control module (WCM) will disable the return to cut height, tilt, and float presets.
This is done to prevent the hydraulic system from overheating.
1. Shut down the engine, and remove the key from the ignition.
2. Move the platform on the left cab-forward side of the machine to the open position. For instructions, refer to 5.4.1
Opening Platforms – Standard Position, page 319.

3. Loosen inner knob (B) on the needle valve. Adjust the knob
as follows:
• Turn outer knob (A) clockwise to decrease the drop rate
• Turn outer knob (A) counterclockwise to increase the
drop rate
4. Tighten inner knob (B).
5. Check the drop rate. Repeat this procedure as needed.
6. Close the platform. For instructions, refer to 5.4.2 Closing
Platforms – Standard Position, page 320.
Adjusting Reel Drop Rate
When the lower reel switch is pressed, the reel should drop from fully raised to fully lowered in approximately
3–4 seconds. Operators can change the drop rate as needed.
DANGER
To prevent bodily injury or death from the unexpected startup of the machine, always stop the engine and remove the
key from the ignition before leaving the operator’s seat for any reason.
IMPORTANT:
The drop rate should NOT be less than 3–4 seconds; damage to the header or windrower may result if the drop rate is
higher than this.
1. Lower the header fully.
2. Shut down the engine, and remove the key from the ignition.
