Use of the AutoPowr Selector Switch and related CommandCenter settings is the preferred method of controlling engine rpm, but FieldCruise can be considered for certain applications such as PTO operation when baling. FieldCruise utilizes a constant speed governor curve, providing instant response to varying loads. Use of FIELDCRUISE is a trademark of Deere & Company OURX935,000053A 1927MAR061/1 407 122208 PN=89
