OPERATION
4.7.11 Reel Tine Pitch
IMPORTANT:
The following describes the concept 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 (higher cam setting) to pick up crops that are lodged, but rather,
the cam settings are mainly used to determine how the crop will get delivered to the drapers.
The position of the fingers relative to the ground (tine pitch) is not significantly affected by the cam setting. For
example, the cam position range is 33°, but the corresponding finger pitch range is only 5° at the lowest point of
reel rotation.
For best performance, use the minimum cam setting that will deliver the crop past the rear edge of the cutterbar and
onto the drapers.
Choosing a Reel Cam Setting
The following outlines the function of each cam setting and includes guidelines for set-up in various crop conditions.
The setting numbers are visible above the slots on the cam
disc. Refer to
Adjusting Reel Cam, page 158 .
Cam Position 1, Reel Position 6 or 7 delivers the most
even crop flow onto the drapers without fluffing up or
disturbing the material.
• The crop is released quite close to the cutterbar and
works best with the cutterbar 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. Initially, have the reel speed set about
equal to the ground speed.
