Vehicles for applying solid organic fertilizers PRT-7A

Machine PRT-7A is designed for applying solid organic fertilizers and transportation of various agricultural goods in the unit with tractors. Vehicles for applying solid organic fertilizers PRT-7A has a number of obvious advantages over the previously produced machines: by changing the spreading device grinds better insertion fertilizer; the use of hydraulic reverse drive operating conveyor provides smooth stepless control of its speed, and therefore the dose of fertilizer application; Reversing hydraulic conveyor allows a single shift lever of the tractor control valve to enable reverse in the event of seizure spreading drums with foreign objects; used in the construction of spring-loaded tension stars increases the reliability of the drive and provides automatic drive chain tension spreading drums and an overall improvement in working conditions mechanic; increased lateral stability.
