[0002] Wheeled tractors, wheeled harvesters and other equipment all have self-propelled power machines for towing and driving operating machinery to complete various mobile operations. Wheeled tractors, wheeled harvesters and other equipment often slip and sink during operation, which makes it difficult to effectively use the power of tractors, wheeled harvesters and other equipment, and seriously damages the soil structure. In mountainous areas with large ground slopes, ordinary tractors, wheeled harvesters and other equipment have limited climbing capabilities. As farmers' wheeled tractors and wheeled harvesters have become larger in recent years, the fields have become deeper and deeper, making it difficult to operate during the busy farming season in spring and autumn. Crawler or semi-crawler tractors have more advantages in paddy fields and mountainous areas.

[0003] However, in the prior art, the track tightness of the semi-crawler traveling device is automatically adjusted by a telescopic rod, but when the tensioning wheel is squeezed by gravity, the telescopic rod will shrink, which will cause the track tension to loosen, affecting the normal operation of the semi-crawler traveling device, and it is impossible to limit and fix it after the tension is adjusted. In addition, agricultural tractors often pass through fields such as silt, and a large amount of silt is often attached to the edge of the track. This silt is inconvenient to clean and often enters the inside of the track, seriously affecting the normal travel of the track. This application proposes a rubber semi-crawler traveling device with a wheel-side reducer to solve this problem.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
