Abstract:
A tractor-mounted system that is convertible from a rotary cutting system to a backhoe, comprising:a. a frame structure for mounting to the rear of a tractor; b. a boom structure projecting from the frame structure; c. in one mode of operation, a rotary cutter mounted to the boom structure for cutting grass and other vegetation; d. the rotary cutter adapted to be disconnected from the boom structure; e. in another mode of operation, a bucket mounted to the boom structure such that said system is converted to a backhoe; f. a first hydraulic cylinder mounted to the boom structure for cooperating with the boom structure to connect either the rotary cutter or bucket to both the boom structure and the first hydraulic cylinder; g. wherein in the one mode the rotary cutter is pivotally mounted at one Point to the boom structure and wherein the hydraulic cylinder extends from the boom structure and is operative to connect to the rotary cutter at another point spaced from the point where the rotary cutter is pivotally mounted to the boom structure such that the rotary cutter is suspended from the boom structure and wherein the rotary cutter while suspended from the boom structure may be articulated on the boom structure by the first hydraulic cylinder; and h. in the other mode the bucket is pivotally connected at one point to the boom structure and wherein the hydraulic cylinder extends from the boom structure and is operative to connect to the bucket at another point spaced from the point where the bucket is pivotally connected to the boom structure, and wherein the bucket can be articulated on the boom structure by the first hydraulic cylinder.
