Personal injury or death could result when towing a disabled machine incorrectly.Block the machine to prevent movement before releasing the brakes. The machine can roll free if it is not blocked.Follow the recommendations below, to properly perform the towing procedure.
This machine is equipped with spring applied, hydraulic pressure released brakes. If the engine or power train hydraulics are inoperable, the brakes are applied and the machine can not be moved. Unless, a brake release pump is used.These towing instructions are for moving a disabled machine a short distance, only a few feet 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.Attach cable to towing eye on front if pulling forward, or attach to drawbar pin or ripper if pulling to the rear.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 disabled 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.To move the machine when the engine is not operable, a provision has been made to attach a brake release pump.The pressure hose from the pump connects to the steering clutch and brake valve. The pump takes oil from the sump of the pump and pressurizes the brake valve to release the brakes.Brake Release Pump - Connecting
Machine brakes can be released for towing by use of FT1973 Adapter Group (5) and FT1845 Pump Group (1).Before Connection
