The article considers manufacturing techniques and assembling screw propellers of transport vehicles for rice and fish farms. The increase in technological capabilities, reliability and carrying capacity of transport vehicles is achieved by making the propeller screw, with the possibility of its rotation. We called such propellers screw propellers, since along their perimeter along the entire length, multiple-curved curved surfaces are formed in the form of helical grooves of various configurations, sizes and shapes. The spatial form of the screw propellers is made with screw surfaces in the form of helical grooves, which ensures that the transport machines for rice and fish farms are conveyed on land, on water, through swampy and difficult terrain at a sufficiently high speed. As a result of the work performed, not only the designs of screw propellers and their classification were proposed, in which there is a general principle that allows the development of still unknown structures of propellers, but also their manufacturing techniques. The design of screw propellers was performed using the KOMPAS-3D software package using descriptive geometry and engineering graphics
