OPERATING THE MOWER CONDITIONER
7.11 The Overshot Auger
The overshot auger is designed to feed the cut crop from the cutterbar into the conditioner rolls.
The vertical and fore-aft positions of the auger can be adjusted to suit the crop conditions for optimal movement of
the crop, minimized wrapping, and to keep the cutterbar clear.
The auger flighting should NEVER contact the pan or stripper bars.
The auger position has been factory set and should not normally require adjustment.
For fine stemmed crop, the auger performs best when set as close as possible to the pan and stripper bars without
rubbing. This is especially important in grass and other crops which have a tendency to wrap.
Component wear may cause clearances to become excessive, resulting in feeding problems and uneven windrows.
7.11.1 Adjusting the Overshot Auger
If necessary, adjust the auger position as follows:
