Towing Information (General)
Personal injury or death could result when towing a disabled machine incorrectly.Be sure all necessary repairs and adjustments have been made before a machine that has been towed to a service area, is put back into operation.Follow the recommendations below, to properly perform the towing procedure.
These towing instructions are for moving a disabled machine a short distance, at low speed, no faster than 2 km/h (1.2 mph) to a convenient location for repair. These instructions are for emergencies only. Always haul the machine if long distance moving is required.Shielding must be provided on the towing machine, to protect the operator if the tow line or bar should break.Do not allow operator on the machine being towed, unless the operator can control the steering and/or braking.Before towing, make sure the tow line or bar is in good condition and has enough strength for the towing situation involved. Use a towing line or bar with a strength of at least 1.5 times the gross weight of the towing machine, for a disabled machine stuck in mud or when towing on a grade.Do not use a chain for pulling. A chain link may break causing possible personal injury. Use a wire rope cable with loop or ring ends. Use an observer in a safe position to stop the pulling procedure if cable starts to break or unravel. Stop pulling whenever the pulling machine moves without moving the towed machine.Keep the tow line angle to a minimum. Do not exceed a 30° angle from the straight ahead position.Quick machine movement could overload the tow line or bar and cause it to break. Gradual and smooth machine movement will work better.Normally, the towing machine should be as large as the disabled machine. Satisfy yourself that the towing machine has enough brake capacity, weight and power, to control both machines for the grade and distance involved.To provide sufficient control and braking when moving a disable machine downhill, a larger towing machine or additional machines connected to the rear could be required. This will prevent it from rolling uncontrolled.The different situation requirements cannot be given, as minimal towing machine capacity is required on smooth level surfaces to maximum on inclines or poor surface conditions. Two tow hooks have been provided. The primary one is the drawbar, and a secondary one (arrow) is located at the front of the machine.This machine is equipped with hydraulically applied dry disc brakes. The brakes are boosted by a hydraulic accumulator which provides at least five braking applications with the engine stopped. Because the hydraulic oil bleeds off in the accumulator, braking capability with the engine stopped will diminish after the engine has been stopped for several minutes.Towing the machine with the engine stopped may be accomplished by disengaging the axle shafts from the bull gears in the final drives. The disc brakes will then still be functional but the effort required to apply them will be much greater. With the axle shafts disengaged, the driveline parking brake
