Increasing tractor weight during agricultural operations is one of ways to optimization the performance of tractor tires interacting with soil. One of these methods is adding weight on the front of the tractor, which leads to better engagement of front tires with soil. In four-wheel drive tractors also causes better steering wheel drive tractors, in addition it prevents from weight transfer to the rear of the tractor, which causes overturning. In this research, a new approach has been proposed that proves automatic weight transfer is possible by putting some lightweight instead of main weights on the front of the tractor. To do this, a number of weights to a specified amount were added on the front of the tractor which could be moved by using a mechanical joint and a hydraulic jack (considering working condition and ground conditions). Traction force and slop of land that have the most impact on weight transfer were measured by a dynamometer and an inclinometer. Also the critical values of these parameters were controlled by an electronic circuit. Results prove that the applied system on the tractor was able to control dynamic weight transfer also the longitudinal balance on the tractor was investigated by performing an experiment on a sloping surface, and good results were detained.
