Reel Tine Pitch; Reel Cam Settings - MacDon D65 Operator's Manual

3.7.10 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 flattened and severely lodged crops. It is not always necessary to increase
the tine pitch (select a higher cam setting) to pick up lodged crops, however, because the cam setting is mainly used
to determine how the crop gets delivered onto the drapers.
The positioning of the fingers relative to the ground (tine pitch) is not significantly affected by the cam setting. For
example, with the cam position range at 33°, the corresponding finger 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

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 flow onto the drapers without fluffing up 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 fluffed or if there is a disruption to
the flow across the drapers, decrease the cam setting.
• This setting generates a fingertip speed that is
approximately 20% faster than the reel speed.
