Reel wrapping in tangled and
weedy crops causing improper reel
delivery.
Reel speed too fast.
Reduce speed of reel to allow
weedy crops to feed into auger
properly.
24
Reel position does not suit
conditions.
Position reel downward as close
as possible to knife and pan.

Lean bar not leaning crop
away from reel.
In tall crops, install lean bar
extensions (part of tall crop kit).

Reel carrying crop over causing
improper reel delivery.
Reel speed too fast.
Reduce reel speed so crop will not
carry over top of reel. Reel should
turn just enough faster than
ground travel so the crop feeds up
auger pan and into auger.

Position reel rearward, as close as
possible to auger and downward
as close as possible to knife and
pan.
