This range of front axle is designed for four-wheel drive tractors and related engineering vehicle with power ranging from 80HP to 90HP. It adopts the advanced steering drive axle design with double reduction structure. The inner half shaft is connected with the drive shaft via a constant velocity joint. The ductile iron housing is strong and light weight. The product is designed with middle-positioned drive shaft, and a central swing type balance pin. The fully hydraulic front wheel steering system supports maximum steering angle of 50 degrees.
Due to our reliable product quality, we have cooperated with many Chinese famous tractor manufacturers. For instance, our YT800 tractor front axle assembly has been acquired by Tianjin Tractor Manufacturing Corporation Ltd., and our YT80-90 four-wheel drive axles have been acquired by Shifeng Group. Upon request, we can also supply custom-made products.
