4.7.6 Draper Speed

The draper speed is controlled with the windrower Cab Display Module (CDM). Refer to your windrower operator's
manual for instructions.
Adjust the draper speed to achieve good feeding of crop for a good windrow. Excessive draper speed will reduce
draper life.

4.7.7 Knife Speed

The header knife drive is driven by the windrower hydraulic pump and is controlled with the windrower Cab Display
Module (CDM). The default speed is 1200 strokes per minute (spm). Refer to your windrower operator's manual.

Depending on crop height, adjust reel height to carry material past the knife onto the drapers. Operate windrower
hydraulics as required. Refer to section
Indications that reel may be too low are as follows:
• Crop loss over the header backtube
• Disturbance of crop on the drapers by the reel fingers
• Crop being pushed down by the tine tubes
Refer to Section 4.6.1 Header Settings, page 46
