Reel Tine Pitch
IMPORTANT:
The following describes the conceptual and operational guidelines of the pick-up reel. Please read carefully
before operating the machine.
The pick-up reel is designed to pick up
fl
attened and severely lodged crops. Because the cam setting is mainly
used to determine how the crop gets delivered onto the drapers, it is not always necessary to increase the tine pitch
(select a higher cam setting) to pick up lodged crops.
The positioning of the
fi
ngers relative to the ground (tine pitch) is not signi
fi
cantly affected by the cam setting. For
example, with the cam position range at 33°, the corresponding
fi
nger pitch range is only 5° at the lowest point of
the reel’s rotation.
For the best results, use the minimum cam setting that delivers the crop past the rear edge of the cutterbar and onto
the drapers. Refer to
3.6.2 Header Settings, page 39
.
Reel Cam Settings
The following outlines the function of each cam setting and provides set-up guidelines for various crop conditions.
The setting numbers are visible above the slots on the cam disc. Refer to
Cam Position 1, Reel Position 6 or 7
delivers the most
even crop
fl
ow onto the drapers without
fl
uf
fi
ng or disturbing
the material.
• This setting will release crop close to the cutterbar and
works best if the cutterbar is on the ground.
• Some crops will not be delivered past the cutterbar
when the cutterbar is raised off the ground and the reel
is pushed forward; therefore, set the initial reel speed
approximately equal to the ground speed.

Cam Position 2, Reel Position 3 or 4
is the recommended
starting position for most crops and conditions.
• If the crop is stalling on the cutterbar when the reel is in
the forward position, increase the cam setting to push
the crop past the rear edge of the cutterbar.
• If the crop is getting
fl
uffed or if there is a disruption to
the
fl
ow across the drapers, decrease the cam setting.
• This setting generates a
fi
ngertip speed that is
approximately 20% faster than the reel speed.
