The Bush Winch is a light weight self-recovery system for 4WDs and 2WDs. When needed the Bush Winch is simply connected to the front or rear wheels of your vehicle as you chose.

With the winch rope attached to the Bush Winch at one end and the anchor point at the other the winch rope winds onto the Bush Winch as the wheel spins.
You can chose to go backwards or forwards until you are pulled onto firm ground again. Take the Bush Winch off again when finished and store it and the winch rope in the kit bag.
The Bush Winch connects and disconnects simply by hand without any tools and the winch rope is very strong, soft to touch, light weight and easy to handle.There are no additional requirement for a bull-bar or any electrical or mechanical parts
