When Break in, you can have the tractor in either low or high, depending on the weight of the load. When

fully open. When break in, pay attention to:
 The operating performance of the engine, the drive system, and the steering system.
 The instrument panel.
 Whether the clutch, gearbox, auxiliary box, front drive axle and brake operate normally.
 Whether you can engage and disengage the differential lock.
 The proper functioning of all of the electrical equipment.
 Any abnormality that occurs during Break in. Troubleshoot and fix if necessary, then continue to run in.
