Rear Axle Spacing

On a combine equipped with a Hillco Leveler the rear axle has a greater rotation range. As a result the
rear axle spacing must be changed to prevent shield interference. Refer to the diagram below and the
following charts for Hillco's rear axle spacing recommendations. Hillco recommends operating the rear
axle in the High Clearance Position on combines equipped with a hillside leveling system.
