The TSU-4 chassis with a stationary drilling rig of URB-2A2 type installed as an attachment. Also in the gap between the cabin and the installation on the frame of the chassis installed piston four-cylinder compressor type 4VU1 with a drive from the transfer gearbox, which also installed the main pump for rotation of the hydraulic motor gearbox on the drill string.
The use of drilling equipment on the basis of the caterpillar chassis of the tractor allows to carry out drilling works on soils of all categories of hardness in hard-to-reach areas by percussive-rotary method with simultaneous cleaning of the well by flushing or blowing, as well as by dry auger. In addition, a pusher is installed at the front, controlled from the cabin by means of a hydraulic control valve, which makes it possible to move various obstacles and pre-prepare the working site for drilling
