Predicting grain tank levels when on slopes or hills

A method for controlling a combine including a chassis, a feeder housing for receiving harvested crop, a separating system for threshing the harvested crop to separate grain from residue, a grain tank for storing the separated grain, a grain tank level sensor for detecting a grain level in the grain tank, an inclination sensor for detecting inclination of the combine, and a controller that controls the combine, the method comprising:

• receiving, by the controller, the grain tank level from the grain tank level sensor;
• receiving, by the controller, an inclination value from the inclination sensor;
• adjusting, by the controller, the grain tank level based on the inclination value;
• and
• alerting, by the controller, an operator of the adjusted grain tank level.
