How Tractors Work

There is a traction seat support on each side of the seat cover made of pressed steel plate, which is connected to the seat cover with a pin. The traction seat base can rotate forward and backward relative to the seat cover with the pin as the center. The bottom surface is connected to the towed trailer with bolts. A locking mechanism composed of horseshoes, diagonal irons, knuckles, adjustment plates, cross bars, pull rods, and springs is provided under the seat cover. The horseshoe is fixed on the seat cover. The pin connects the knuckle, pull rod and cross bar, the inclined iron is also connected by the pin, and the pull rod is connected to the rib plate under the seat cover by a spring. It is characterized in that the two tail parts behind the saddle-shaped seat cover are large arcs, and there is a butterfly-shaped concave surface in the middle, which divides the entire plane into five parts of similar size.
