Abstract
A ripper pitch hold system and method for a ripper that includes pitch and lift cylinders. The system includes operator pitch and lift inputs, operator pitch hold input, cylinder position inputs, and a controller. The controller processes the inputs and generates pitch and lift cylinder commands that maintain the ripper pitch angle at a pitch hold setting. The controller can update the pitch hold setting with and maintain the pitch angle at the latest operator pitch input. Alternatively, the controller can cease to process operator pitch inputs, and maintain the pitch angle at the pitch hold setting. The pitch hold input can include an activation control, and pitch selector. The pitch angle and pitch hold setting can be set to the angle selected by the pitch selector. The pitch selector can include operator adjustable and fixed pitch settings. Operator adjustable executing operator pitch commands and fixed ignoring operator pitch commands.
