  • Patent number: 8038518
    Abstract: An agricultural combine includes a supporting structure. A work assembly is coupled to the supporting structure. The work assembly has a plurality of components to assist in the performing of crop processing operations. The work assembly is configured to define an air stream path. The work assembly has at least one rotary component that generates an air stream that flows through the air stream path to aid in crop processing in the work assembly. A fluid system is configured to circulate a fluid. The fluid system includes a fluid cooler that is positioned at a location in the air stream path to provide cooling of the fluid.
    Type: Grant

  • Patent number: 6722112
    Abstract: A mechanism is provided for engaging and disengaging the reverse operation of a feederhouse of a harvesting apparatus. The mechanism solves the problem of accurate engagement between the shift collar or driving element and the reverse gear, teeth or splines and the forward gear, teeth or splines of the feederhouse transmission. The mechanism comprises an actuator, electrically controlled, which loads or compresses a spring, wherein the spring exerts a shifting force on a shift shaft or shift fork of the gearbox which automatically moves the shift collar or driving element of the transmission into either a forward or reverse drive position when the gear, teeth of splines of the shift collar is aligned or meshed with the gear, teeth or splines of either the reverse or forward drive of the feederhouse transmission.
