The cross-riding support wheel is uniformly forced and the service life is doubled, which reduces the maintenance of the user. At the same time, the whole weight of the machine is distributed evenly on our Changfa special-made crawler and the grounding pressure is small, just to make a high pass capacity of the wet and muddy field.

Using Guihang 37CC displacement HST. When working in the field, it turns to be more flexible and faster in steering, also improved the efficiency of operation.

Using the 90×48×450 crawler, the average grounding pressure is smaller and the service life is over 1000 hours.

The minimum clearance from the ground is 190 mm, which is more stronger when working in wet and muddy fields.
