A wheel adjustment system for an agricultural implement includes a controller having a processor and a memory. The processor is configured to receive a first signal indicative of a ground speed of the agricultural implement, receive a second signal indicative of a desired position of a wheel of the agricultural implement, receive a third signal indicative of a current position of the wheel of the agricultural implement, and output a control signal to adjust a position of the wheel of the agricultural implement based on the first signal, the second signal, and the third signal, wherein a rate of adjustment of the position of the wheel varies based on the first signal.

A variable track wheel comprises a rim suitable for receiving a tire, and a disc through which said wheel is mountable on a hub, said disc being removably secured by fastenings to a connecting member provided in said rim, said connecting member projecting towards a rotation axis of said wheel, said wheel further comprising a plurality of spacers interposed between an annular perimeter zone of said disc and said connecting member of said rim, said disc and said rim being mountable in a plurality of reciprocal axial positions and in a plurality of reciprocal orientations to obtain a variation in the track of said wheel, said wheel further comprising at least one centering device for mutual positioning of said disc and of said rim said centering device comprising a hole and a pin said hole or said pin being provided in said connecting member or in said disc said centering device further comprising a coupling element so conformed as to cooperate with said hole and with said pin for reciprocally coupling said pin and said hole.
