The invention relates to a wheel space adjusting device. The wheel space adjusting device comprises a widened outer square tube, a widened inner plate, a widened inner square tube, a widened baffle plate and a widened oil cylinder; the widened inner plate is mounted inside the widened outer square tube by use of a bolt; the widened inner square tube is nested into the widened inner plate; one end of the widened inner square tube is located inside the widened outer square tube, while the other end of the widened inner square tube is fixedly connected with the widened baffle plate; the widened baffle plate is connected with a frame with wheels by use of a bolt; one end of the widened oil cylinder is hinged to the widened outer square tube, while the other end of the widened oil cylinder is hinged to the widened baffle plate. The stretching of the widened oil cylinder is capable of realizing the movement of the widened inner square tube in the widened outer square tube, and therefore, the wheel space can be increased or reduced, and the process is of stepless change and can be locked in any position; as a result, the wheel space adjusting device is adaptive to the row spaces of different crops. The wheel space adjusting device is simple and reliable in structure and high in durability.
