Reel Speed
IMPORTANT: Excessive reel speed causes premature wear to reel bushes and fingers.
Reel speed is in cab controlled and can be adjusted manually or set to automatic synchronisation (refer to
Combine operators Manual).
Reel speed affects feeding of crop through the knife and onto the drapers, as well as the smoothness and
evenness of the delivered crop. Normal reel speed is 10% faster then the ground speed of the combine.
Indications that reel speed is too slow may be crop loss and dropped heads at the knife. Slow reel speed
also causes uneven cut stubble length.
Indications that reel speed is too fast may be crop loss over the rear of the platform caused by carryover on
the reel or disturbance of crop on the draper belts. It is also the major cause of grain loss by shattering.

Levelling Reel / Minimum Reel Height
IMPORTANT: To avoid damage to the reel, ensure that there is a
minimum of 35mm clearance to the Knife.
1.
Ensure lift ram pins are in the correct position. Pickup reel in the
upper position (A) (as displayed) and bat reel in the lower position
(B).
2.
Extend reel to a position directly above the knife (approx half way).
3.
Adjust pickup reel finger pitch to mid position (this step is not
required for bat reels).
4.
Loosen lock nut (A) (see image).
5.
Turn cylinder shaft (B) until a clearance of 35mm exists between
tip of pick up reel fingers (or bat reel slats) and knife.
6.
Tighten lock nut (A).
