12" auxiliary wheels for HECHT 7100 for taxiing. The wheels are not intended for ploughing. The wheels are equipped with a slip pinion shaft that replaces the differential to some extent. It helps to easily handle the machine. Because the wheels have enough margin to roll when turning, but, at the same time, the pinion automatically prevents the wheels from slipping in soft terrain, similar to a differential lock (see video tab).
For machines from year 2020 only.
