Motor grader blade positioning system and method
First Claim
1. A ground engaging vehicle, comprising:
- a tool connected to the vehicle;
at least one actuator coupled to said tool;
an electronic controller controllably coupled to said at least one actuator, said controller including an operator interface, said controller configured for;
issuing a plurality of commands to said at least one actuator using said operator interface to place said tool in a position relative to the vehicle;
recording forces encountered by said tool as said tool is placed in said position, thereby defining recorded forces;
recording said commands;
positioning said tool in an other position different from said position;
replaying at least some of said commands recorded in said recording step thereby repositioning said tool substantially in said position; and
ensuring said tool is not constrained from reaching said position.

Abstract
A ground engaging vehicle having a tool connected to the vehicle, at least one actuator coupled to the tool and an electronic controller. The electronic controller is controllably coupled to the at least one actuator. The controller includes an operator interface. The controller is configured for issuing a plurality of commands, recording the commands, positioning the tool and replaying at least some of the commands. The issuing step includes issuing a plurality of commands to the at least one actuator using the operator interface to place the tool in a position relative to the vehicle. The recording step records the commands issued in the issuing step. The positioning step includes positioning the tool in another position different from the position. The replaying step includes replaying at least some of the commands recorded in the recording step, thereby repositioning the tool substantially in the original position.
