Improper hookup and towing is dangerous and could result in injury or death to yourself or others. The towing connection must be rigid, or towing must be done by two machines of the same size as the towed machine. If two machines are used, connect a machine on each end of the towed machine. If only one machine is used for towing, that machine must be larger than the towed machine. Be sure that 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 that are listed below in order to perform the towing procedure.
This machine is equipped with brakes that are applied by hydraulic pressure. The brakes are released by springs. The parking brake must be disengaged before towing the machine. If the parking brake is engaged, the machine cannot be moved.

Towing of a disabled machine with the engine stopped may cause transmission damage. The transmission will not have lubrication. Do not tow a disabled machine any farther than is necessary to provide for a convenient location for repairs. |
These towing instructions are for moving a disabled machine for a short distance at low speed. Move the machine at a speed of
Shielding must be provided on both machines. Shielding will protect the operator if the tow line or the tow bar breaks.
Do not allow an operator to be on the machine that is being towed unless the operator can control the steering and/or the braking.
Before you tow the machine, make sure that the tow line or the tow bar is in good condition. Make sure that the tow line or the tow bar has enough strength for the towing procedure that is involved. The strength of the towing line or of the tow bar should be at least 150 percent of the gross weight of the towing machine. This is true for a disabled machine that is stuck in the mud and for towing on a grade.
Keep the tow line angle to a minimum. Do not exceed a 30 degree angle from the straight ahead position.
Quick machine movement could overload the tow line or the tow bar. Quick machine movement could cause the tow line or the tow bar to break. Gradual, steady machine movement will be more effective.
Normally, the towing machine should be as large as the disabled machine. Make sure that the towing machine has enough brake capacity, enough weight, and enough power. The towing machine must be able to control both machines for the grade that is involved and for the distance that is involved.
You must provide sufficient control and sufficient braking when you are moving a disabled machine downhill. This may require a larger towing machine or additional machines that are connected to the rear. This will prevent the machine from rolling away out of control.
All situation requirements cannot be listed. Minimal towing machine capacity is required on smooth, level surfaces. When you are on inclines or on surfaces in poor condition, maximum towing machine capacity is required.
Attach the towing device and the machine before you release the brakes. If equipped, disengage the front wheel drive.
Consult your Cat dealer for towing a disabled machine.
If the engine is running, the machine can be towed for a short distance under certain conditions. The power train and the steering system must be operable.
- Place the transmission control switch in the NEUTRAL position.
- Raise the attachments off the ground.
If the engine is dead, perform the following steps before towing the machine.

- Activate the secondary steering pump on the stopped machine. Refer to Operation and Maintenance Manual, "Monitoring System" for activation of the secondary steering pump. You can steer the machine while the secondary steering pump is on. The secondary steering pump will be activated for a maximum of 10 seconds. While the secondary steering pump is activated you can use the joystick to align the front wheels of the machine.
- Remove the drive shaft that is located between the differential and the transmission. Consult your Cat dealer or refer to Disassembly and Assembly Manual, "Drive Shaft - Remove and Install" for removal and installation of the drive shaft.

When the driveshaft is removed, the machine has NO parking brake. The machine can roll and cause personal injury or death.
Block the wheels securely so that the machine cannot move.
If the brakes are in good operating condition, the machine has limited wheel brake ability.
The towing connection must be rigid, or towing must be done by two machines of the same size or larger than the towed machine. Connect a machine on each end of the towed machine.
- Fasten the tow line or the tow bar.
- Remove the wheel blocks. Tow the machine slowly. Do not tow the machine faster than
2 km/h (1.2 mph) .
