A general purpose combined harvester and thresher comprising a first rotor ( ) and a second rotor ( ) provided in a thresh unit ( ) and arranged longitudinally in parallel to each other with axes thereof right and left, and a first receiving net ( ) and a second receiving net ( ) arranged below the respective rotors to define a first treating chamber (D ) and second treating chamber (D ). A grain tank ( ) is arranged above the threst unit ( ), a base end of a discharge auger ( ) is arranged outside the grain tank ( ), an engine ( ) is arranged behind the grain tank ( ), and a transmission casing ( ) is arranged below the engines A tooth bar (T ) is provided on an outer peripheral surface of the first rotor ( ) facing a grain rod inlet ( ), and a screw vane ( ) has a pitch (P) equal to a width of a rear end of a feeder housing ( ). A terminal end of a return conveyor ( ) for returning of a second product communicates with the first treating chamber (D ).

General purpose combined harvester and thresher

A tracked agricultural combine vehicle for harvesting, hulling and sorting grain includes a grain working section driven via a tension roller clutch controlled power transmission belt and further including integrated control means for left and right side propulsion track assemblies wherein individual track steering commands in the form of differential track speed control are derived from a common steering wheel input; vehicle speed is controlled by a single input means which controls the speed of both tracks.
