Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a widened front drive axle assembly for agricultural machinery with large ridge spacing. Background Technology

[0002] Tractors are indispensable power machinery in modern agriculture, and the performance of their drive axles directly affects the traction, maneuverability, and operational efficiency of the entire machine. In Northeast China, the 1.3-meter wide ridge double-row planting pattern for corn requires a tractor wheel track of at least 2600 mm to ensure stable operation. However, the wheel spokes of traditional tractor drive axles are relatively narrow, with a maximum width of only 1924 mm, which cannot meet the requirements for wide ridge spacing. If tractors with existing wheel tracks are forced to operate on wide ridges, the tires will not align with the ridges, affecting operational accuracy and efficiency, and even causing crop damage. Currently, users often adjust the wheel track by adding wheel track extension devices or replacing the axle with a longer one, but these methods are complex in structure, costly, and may affect the strength of the axle frame and steering performance.
