Abstract: A loader which can be used most effectively on construction projects for excavation and loading of loose materials, and in agriculture for the mechanization of such jobs as loading of fertilizer, peat and root crops. The loader is provided with a frame for mounting the load-handling equipment on the tractor body. The frame consists of side members, rigidly secured at one end by a cross member while at the other ends they are fastened by ball supports on the rear axle of a tractor on both sides of its body. Each side member consists of two parts interconnected by a locking device allowing their rigid connection and separation, with one of the parts carrying the load-handling equipment and installed with a provision for being removed together with this equipment by moving axially a bar which fastens the cross member on the tractor body. Such an arrangement ensures rapid installation and removal of the load-handling equipment without the use of load-hoisting devices.
