Problems solved by technology

[0002] At present, it is a very common technology for tractors to adjust the speed output of the tractor through the transmission mechanism to realize various operating functions of the tractor. In most tractor gearboxes, in order to realize the functions of shifting speed and direction of the tractor, a The combination of multiple gears and direction changing gears to realize the speed changing and direction changing functions of the tractor has resulted in too many internal gears in the gearbox, and the speed change mechanism is too complicated, which will also make the box of the gearbox too large, providing The gear positions of the tractor may not be able to fully meet the needs of the tractor in various special ground conditions and special operations, and the operation stroke is too large during the gear shift operation, which makes the operation difficult, which limits the use of the tractor and affects the normal operation of the tractor. construction work
