Reduce speed before you need to apply brakes. When towing a pull-type combine at transport speeds, a tractor or truck may skid if you stop too quickly, especially on loose gravel. Slowing too quickly while turning a corner can cause jackknifing of tractor and combine. Self-propelled combines should be towed on roads only if it is absolutely necessary. Even though it may be easier to tow from the rear, towing from the front is preferable.
Visibility is better and there are stronger structural members for fastening the tow chain in front.
Follow instructions in your operator's manual. To haul the combine on a truck or trailer, fasten the combine at each drive wheel and at the rear. Lock the brake pedals together and use wheel chocks to block each side of the drive wheels. Be sure you know the height, width, and weight of the load, and check local and state regulations. Watch for narrow culverts and bridges and low-clearance objects like overpasses and power lines.
