OPERATION The towing machine should normally be of the same class as the machine being towed. Check that the towing machine has ample braking power, weight, and rimpull to allow it to control both machines while on a slope. When towing the machine downhill, use a larger machine for towing to provide ample rimpull and braking power, or connect another machine to the rear of the machine being towed, in order to prevent either machine from loosing control and turning over. Towing may be necessary under many different conditions, therefore it is impossible to determine beforehand all the requirements for towing.
Towing on flat horizontal roads will require minimum rimpull, while towing on slopes or uneven road surfaces will require maximum rimpull. 16.2.1 WITH THE ENGINE RUNNING If the transmission and steering wheel can be operated, and the engine is running, it is possible to tow the machine a short distance, such as out of the mud or to the edge of a road. The operator should sit on the machine being towed and operate the steering in the direction that the machine is being towed. 16.2.2 WITH THE ENGINE STOPPED When towing a machine with the engine stopped, use the following procedure. 1. The transmission oil does not lubricate the system, therefore remove the front and rear drive shafts.
If necessary, block the tires to prevent the machine from moving. 2. The steering cannot be operated, therefore remove the steering cylinder. Even if the brakes are in good condition, there is no change in operating force to the brake pedal, but the braking force is reduced each time the pedal is depressed. 3. Connect the towing equipment securely. When carrying out towing operations, use two machines of the same class as the machine being towed. Connect one machine to the front and one to the rear of the machine being towed, then remove the blocks from the tires and tow the machine. 2-81 WA320-3MC
