PICK-UP REEL ADJUSTMENTS
The reel has a series of adjustments which affect crop flow into the sickle and conveyors. This section
describes these adjustments and gives recommended settings for several crops and conditions. The Trouble
Shooting section of this manual includes some tips to improve performance.
Finger Pitch is the angle the fingers operate at in relation to the ground. In the illustration below, finger pitch
on right is more aggressive than pitch on left. Generally, a more aggressive finger pitch is required for crops
that are down, tangled or matted. A less aggressive finger pitch is suitable for standing crop.
Adjustment of the finger pitch is achieved in two stages:
1. Select Cam Arm Position - This is a major
adjustment made by moving cam arm mounting
bolt to position X or position Y as shown. All cam
arms at both ends of the reel must be in the same
position. Position X is a less aggressive setting,
recommended for standing or partially down
crops. Position Y is a more aggressive setting,
recommended for down and tangled crops.

ADVANTAGES
Best release of
crop.

Larger "bite"
(more gather) at
crop entry.
Lighter loads on
Y
reel and drive.
Better lifting
action.
2. Select Finger Pitch - This is a fine-tuning adjustment made by selecting range slot P or Q and pitch notch J,
K, L, M, N or O. Range slot P is more aggressive than slot Q. Pitch notch J is least aggressive, notch O is
most aggressive. Select a position aggressive enough to provide sufficient lift, yet still release crop properly.
TIP: In bushy crop that sits high on the drapers or augers, try a more aggressive finger pitch to reduce
carry-over.
