A harvester head may include a frame, a roller configured to support a draperbelt and at leastone tracking correction arm. The roller has a rotational axis and is pivotablysupported by theframe about at least one pivot axis nonparallel to the rotational axis. The atleast one trackingcorrection arm is coupled to the roller and may include a first belt bump stopand a secondbelt bump stop. The first and second belt bump stops contact portions of thedraper belt suchthat mistracking of the draper belt relative to the roller pivots the rollerabout the pivot axisuntil the draper belt is automatically moved back into a tracking relationshipwith the roller.
