The harvester has been retrofitted with anti sinking half chain rail mud for stable and reliable leveling

Crawler chassis is a mechanical engineering equipment that is mostly suitable for small light industries and small construction machinery industries. Light industry generally refers to agricultural machinery within one to four units. The construction machinery industry is mostly used in the small-scale drilling industry. Track chassis can be roughly divided into two types based on track material: rubber track chassis and steel track chassis.

Crawler walking mechanisms are widely used in field work vehicles such as construction machinery and tractors. The walking conditions are harsh, requiring the walking mechanism to have sufficient strength and stiffness, as well as good walking and turning capabilities. The tracks are in contact with the ground, while the drive wheels are not in contact with the ground. When the motor drives the driving wheel to rotate, the driving wheel continuously rolls up the track from the rear through the meshing between the teeth on the driving wheel and the track chain under the action of the driving torque of the reducer. The grounded part of the track exerts a backward force on the ground, while the ground correspondingly exerts a forward reaction force on the track, which is the driving force that propels the machine forward. When the driving force is sufficient to overcome the walking resistance, the supporting wheels roll forward on the surface of the track, causing the machine to move forward. The front and rear tracks of the whole machine's track walking mechanism can turn independently, making its turning radius smaller
