3.7.8 Reel Height

The crop type and condition determines the operating height of the reel.
Set the reel height to carry material past the knife and onto the drapers with minimal disturbance and damage to the
cut crop. Also, refer to 3.7.9 Reel Fore-Aft Position, page
The reel height is controlled using switches in the windrower cab.
The following conditions might result if the reel is set too low:
• Crop loss over the header backtube
• Crop disturbance on the drapers caused by the reel fingers
• Crop being pushed down by the tine tubes
The following conditions might result if the reel is set too high:
• Cutterbar plugging
• Crop lodging and being left uncut
• Grain stalks dropping ahead of cutterbar
Refer to 3.6.2 Header Settings, page 44
IMPORTANT:
Maintain adequate clearance to prevent fingers contacting the knife or the ground. Refer to
to Cutterbar, page 186.

3.7.9 Reel Fore-Aft Position

Reel fore-aft position is a critical factor for achieving the best results in adverse conditions. The reel position is
factory-set for normal conditions, but it can be adjusted forwards or backwards as required using the controls
inside the cab.
The reel can be moved approximately 9 in. (227 mm) further aft by repositioning the fore-aft cylinders on the reel
arms to accommodate certain crop conditions.
