First Claim
1. A machine, comprising:
- a frame;
a plurality of ground engaging elements supported on the frame;
a work tool pivotably attached to the frame using a lift arm assembly and a tilt linkage;
at least one device for measuring a quantity associated with at least one of the lift arm assembly, the tilt linkage, and the work tool; and
an electronic controller in communication with an operator display and the at least one device, wherein the electronic controller is configured to store an operator selected orientation of the work tool, calculate a current orientation of the work tool based at least in part on the quantity, calculate a deviation of the current orientation of the work tool from the operator selected orientation, and display a visual representation of the deviation of the current orientation of the work tool on the operator display.

Abstract
A machine includes a plurality of ground engaging elements and an operator control station supported on a frame. A work tool is pivotably attached to the frame using a lift arm assembly and a tilt linkage. At least one device measures a quantity associated with at least one of the lift arm assembly, the tilt linkage, and the work tool. An electronic controller, in communication with an operator display and the at least one device. The electronic controller is configured to store an operator selected orientation of the work tool, calculate a current orientation of the work tool based on the quantity, and calculate a deviation of the current orientation from the operator selected orientation. A visual representation of the deviation is displayed on the operator display.
