ABSTRACT:
A tractor transmission having an input shaft, a PTO system transmission shaft disposed thereunder, a gear-type speed change mechanism for changing the number of rotations of the input shaft, and oil reservoir. A gear in engagement with the gear in said gear-type speed change mechanism is rotatably disposed at said PTO system transmission shaft and blades are disposed at the boss of this first-mentioned gear. At least one side of each of said blades is opened toward said oil reservoir. Lubricating oil in said oil reservoir is utilized as resistance to the blades, thereby to stop the rotation of the gear-type speed change mechanism otherwise caused due to the force of inertia.
