AI Technical Summary
Small and medium horsepower tractors have complicated forward and reverse movements, rear power output, and cut-off operations. They also have poor reversing smoothness and are difficult to maintain, especially in high-intensity working environments.
By combining power reversing with wet PTO, the hydraulic wet clutch is used to achieve reversing and power output, reducing cumbersome operations, lowering maintenance difficulty, and improving operating comfort and adaptability.
It achieves seamless power reversal, reduces driver workload, adapts to the frequent start-stop requirements of agricultural machinery attachments, simplifies maintenance, and improves power matching and operational efficiency under different working conditions.

Abstract
Claims
1. A power reversing transmission system for small and medium horse power tractors, characterized by: It includes a reversing clutch shaft (1) and a PTO power output shaft (2) arranged in sequence. A reversing clutch (9) is installed on the reversing clutch shaft (1). A main transmission drive gear shaft (3) and a secondary transmission drive gear shaft (4) are sequentially mounted on the main body of the PTO power output shaft (2). A driven gear shaft (5) and a bevel gear shaft (6) parallel to it are provided on the side of the PTO power output shaft (2). The end of the bevel gear shaft (6) away from the driven gear shaft (5) is connected to the drive axle (30) through a bevel gear. A power output drive gear shaft (7) and a PTO clutch (31) are sequentially arranged on the rear end of the PTO power output shaft (2). Both the reversing clutch (9) and the PTO clutch (31) are hydraulic wet clutches.
2.
