Electrical method for centering telehandler rear wheels

An electrical method for centering telehandler rear wheels, the telehandler including a front steering cylinder, a rear steering cylinder and a steering control unit, the steering control unit is connected to a hydraulic pump, comprising the steps of:

• providing a steer mode valve having a 4W crab position, a 4W circle position, a 2W position and an intermediate position;
• connecting said front steering rear cylinder and said rear steering cylinder to said steer mode valve;
• providing an electronic control module that receives input from said at least one rear wheel sensor;
• shifting said steer mode valve from either said 4W crab position or said 4W circle position into said intermediate position with said electronic control module;
• detecting an angular position of rear wheels connected to the rear steering cylinder;
• straightening the rear wheels by supplying hydraulic fluid to rear steering cylinder;
• requiring the telehandler to be moving before shifting into said 2W position;
• and
• shifting said steer mode valve to said 2W position with said electronic control module.
