FIELD: agricultural engineering. SUBSTANCE: unit contains self-propelled trucks with two tracks for frontal motion of truss with platform. Drive rollers of both tracks are set in motion through universal joints from one-motor reduction gear, thus enhancing accuracy in shifting from one section of farming land to another and maintaining linearity of motion front of self-propelled trucks of multiple-span unit. EFFECT: enhanced reliability of operation. |
