How does Dongfanghong 25p single-cylinder small four-wheel shift?

The gear of Dongfanghong tractor is to step on the right clutch to move forward and backward. The upper part of the shift lever of the old Dongfanghong tractor is equipped with a locking device, which is controlled by the clutch pedal. You can unlock it when you step on it, and you can hang it in any gear at will. When it is released, it can be locked. At this time, the shift lever lost its function and could not be put into gear, whether intentionally or unintentionally, avoiding a lot of unnecessary troubles.
