Claims

[Scope of utility model registration request]

The tractor safety system consists of an arch-shaped upper frame and an H-shaped lower frame, and the lower end of the vertical member of the H-shaped lower frame is attached to the rear axle case, and the horizontal member is attached to the hydraulic case via brackets and cushion members. In the frame, the horizontal member of the lower frame is formed into a channel shape and is attached to cover the upper side of the bracket attached to the hydraulic case, so that the height of the upper surface of the horizontal member is kept as low as possible. Structure of safety frame in tractor.
