REEL SPEED

For best feeding of the crop into the auger, reel
speed should be just faster than ground speed.
This gently sweeps material across the sickle into
the auger.
The reel speed is factory set at 72 rpm. (No-load at
rated tractor RPM.)
With a pulley position exchange, other reel speeds
are possible. (See chart.) A slower reel speed will
reduce excessive crop carry-over, while a faster
reel speed will result in a more even stubble height
in down and tangled crops.
To change reel speed:
a. Loosen jam nut (C) on adjuster bolt and two
flange nuts (D) at reel drive arm. Loosen
adjuster bolt (E) to slacken belt. Remove belt.
b. Remove three flange locknuts at position (A).
c. Remove three bolts and lockwashers at
position (B).
d. Position pulleys to achieve desired reel speed,
(see chart). Replace pulley hardware.
NOTE: For 66 rpm reel speed it will be
necessary to purchase an additional 10
O.D. pulley from your Dealer.
e. Replace reel drive belt and tighten. Check reel
drive chain tension. See Maintenance /Service
section for recommended belt and chain
tension.

REEL POSITION

Reel position has been found to be a critical factor in achieving good results in adverse conditions. The reel
position is factory set for average straight standing crop. It can be adjusted both vertically and horizontally
(fore-aft) for different crop conditions. See the chart below for recommended reel position in unusual crop
conditions. (Continued next page.)
Unusual Crop Condition
· Crop down or lodged
· Wet or dead material collects
on cutterbar, plugging sickle.
· Short crop.
· Thick stemmed or heavy standing crop.
