Claims

[Scope of Claim for Utility Model Registration] A pair of left and right columns connected at the top to form a gate-shaped frame are erected from the rear axle housing.
A horizontal cross member is provided that connects both columns above the rear of the machine, and a vertical cross member is provided that connects the approximate center of this cross member and the hydraulic cylinder case for lifting and lowering the work equipment installed on the rear of the machine. In the agricultural tractor provided with a bracket in the direction of the cross member, the upper part of a substantially box-shaped bracket having a pair of left and right plate members is fixed to the lower surface of the substantially central part of the cross member, and the lower part of both plate members of this bracket extends forward. 1. A frame structure for an agricultural tractor, characterized in that the frame structure is formed into a backward-inclined shape, and a lower part of the bracket is fixed to the upper surface of the hydraulic cylinder case.
