Feeder Having Lateral Tilt for an Agricultural Harvesting Combine

Abstract

Disclosed is a lifting assembly for a crop severing assembly forwardly carried by a tractor having a frame and front a frame and an axle assembly carrying front wheel assemblies. The crop severing assembly has a forward end and a rear end, and includes a pair of bracket assemblies located at the forward end and atop the crop severing assembly. A pair of lift cylinder assemblies each have a lower end and a top end. The lift cylinder lower ends are located at either side of the rear end of the crop severing assembly to bottom brackets extending from the tractor frame forward of the tractor axle assembly and are attached between each cylinder lower end and each cylinder top end to trunnions carried by the crop severing bracket assemblies for pivotally raising and lowering of the forward end of the crop severing assembly.

         9 . An improved feeder house assembly having a front end assembly that carries a grainhead and cylinder assemblies that tilt the carried grainhead about side pivot assemblies, a mechanism for unlocking the front end assembly for permitting grainhead pivoting, which comprises:
 (a) apertures located at the bottom sides of the front end assembly;   (b) laterally extending rods that extend through the apertures and withdraw the laterally extending rods from the apertures, each rod carrying a laterally extending pin;   (c) a pair of bracket assemblies having elongate slots and being attached to the front end assembly adjacent to the laterally extending rods, wherein the laterally extending pins extend into the elongate slots;   (d) a cylinder and rod assembly located between and attached only to the laterally extending rods,   whereby actuating the cylinder and rod assembly moves the laterally extending rods through the apertures and withdraws the laterally extending rods out of the apertures.   
     
     
         10 . The improved feeder house assembly of  claim 9 , wherein the cylinder and rod assembly comprises a linear actuator. 
     
     
         11 . The improved feeder house assembly of  claim 9 , wherein the cylinder and rod assembly is fixedly attached to the front end assembly. 
     
     
         12 . The improved feeder house assembly of  claim 9 , wherein the cylinder and rod assembly is slidingly attached to the front end assembly. 
     
     
         13 . The improved feeder house assembly of  claim 9 , wherein the cylinder and rod assembly is not fixedly attached to the front end assembly.
