7.11.7.3 Front Stripper Bar Extensions
Extensions for the front stripper bar are provided
for installation (if required for certain crop
conditions), or especially in tall crops that cause
material to bunch up at the ends of the
conditioner rolls.
Stripper bar extensions will allow the auger to
carry the crop "more towards the center", rather
than prematurely feeding it to the conditioner.
