A skid steer loader having a main frame including a compartment in which an engine, hydraulic drive components and other elements are contained. A cab is mounted above the compartment on the main frame with load bearing side walls extending upwardly to define an operator control area therebetween. Pivotally mounted on such walls is a boom structure including a pair of arms and a mounting assembly. An engine is operatively associated with the boom structure for raising and lowering each of the pair of arms along a generally vertical path adjacent a corresponding load bearing side wall to which it is coupled by the mounting assembly. A unique noise isolation mounting arrangement is used to couple the cab structure to the main frame, on which cab the entire boom structure is mounted.

Skid steer loader cab mounting apparatus

A skid steer loader having a frame, ground support wheels extending from the frame, a cab with load bearing side walls extending upwardly from the frame to define an operators control area therebetween, and a boom structure comprising a pair of arms and a linkage assembly for operatively coupling the arms to the load bearing side walls. Each arm includes a front portion having a front end extending beyond the cab to support a bucket, a rear portion extending behind the cab, and an integral intermediate portion between the front and rear portions. The linkage assembly includes upper and lower links associated with each of the arms, each link being pivotally secured to the cab at a location above the wheels. The boom structure is powered for raising and lowering in concert each of the pairs of arms through a generally vertical path for moving the front end of the boom arms and bucket along a lift path. The bucket initially moves from a known position near the ground in a substantially vertical direction to an intermediate position in the lift path, and subsequently in a slightly forwardly inclined direction to a second intermediate position, from which it finally moves in a substantially vertical direction to complete its lift path.

A cab is mounted above the compartment on the main frame with load bearing side walls extending upwardly to define an operator control area therebetween. Pivotally mounted on such walls is a boom structure including a pair of arms and a mounting assembly. An engine is operatively associated with the boom structure for raising and lowering each of the pair of arms along a generally vertical path adjacent a corresponding load bearing side wall to which it is coupled by the mounting assembly. The cab is mounted on the frame for conjoint movement of the side walls and the boom structure from an operative position to a remote position to provide unobstructed access to the compartment while maintaining the drive and transmission componentry in an operational mode.

Method and apparatus for tilting a skid steer loader cab

Skid steer loader with tiltable cab

A skid steer loader having a main frame including a compartment in which an engine and transmission components are contained, ground support wheels extending from the main frame, and a cab mounted on the main frame. The cab includes load bearing side walls extending upwardly from the main frame to define an operators control area therebetween. A boom assembly comprising a pair of arms having material handling front portions and linkage structure that operatively attaches the arms to the cab side walls. The linkage structure includes an upper link coupled to each of the arms and pivotally secured to the cab at a location above the top surface of the wheels, and a lower link which is also pivotally secured to the cab at a location above the wheels. The boom assembly raises and lowers the pair of arms through a generally vertical path adjacent the corresponding load bearing side walls and above the wheels which maximizes the space available in the operator control area, whereas the front portions of the boom arms are thereby moved along generally vertical side-by-side paths.

An agricultural baler comprises a bale case having an inlet opening in one side wall thereof; a plunger mounted for reciprocation within the bale case and back-and-forth across the inlet opening; a feeder duct communicating at one end with the inlet opening in the bale case and curving forwardly therefrom; the feeder duct comprising a pair of curved opposed wall means of which is movable relative to the other; and feeder means cooperable with the feeder duct to accumulate a charge of crop material therein and then stuff that charge into the bale case. The movable wall means is movable relative to the other wall means along substantially its entire length such that one cross sectional dimension of the feeder duct is variable along substantially the entire length of said feeder duct to ensure that, in use and as a charge of crop material is being accumulated in the feeder duct, said opposed wall means generally maintain contact with said crop material.

Variable feeder duct for balers

Shielding for agricultural balers

An agricultural baler comprises a bale case having an inlet opening for charges of crop material to be transferred thereto from a feeder duct, a plunger reciprocable within the bale case to compress successive charges of crop material from the feeder duct to form a bale, and a feeder mechanism mounted within the duct to accumulate a charge of crop material therein and then stuff that charge into the bale case. The feeder mechanism comprises a first rotatable tine bar having mounted thereon a first set of packer tines and a set of stuffer tines angularly offset from the first set of packer tines, and a second rotatable tine bar on which is mounted at least a second set of packer tines.

Baler feeder mechanism

An infeed mechanism for a rotary cleaning device for cleaning threshed grain in combine harvesters is disclosed wherein an infeed auger includes a pair of helical flights terminating in a pair of radially extending distributing paddles. The infeed auger is mounted forwardly of a rotatable cleaning cylinder with the distributing paddles being positioned within the axial opening through the cleaning cylinder to discharge threshed grain radially outwardly into individual cleaning shoes. A grain pan is provided within each cleaning shoe to receive the threshed grain discharged from the distributing paddles, each cleaning shoe being operable to reciprocatably move in a generally fore-and-aft direction to convey grain received on the grain pans rearwardly onto sieves also mounted within the cleaning shoes. The infeed mechanism is also provided with an upwardly extending infeed chute that is flared outwardly from top to bottom to serve as a conduit for the infeed of threshed grain into the infeed auger.

Infeed mechanism for rotary cleaning device in combines

Augers used in farm machinery are generally rotatably mounted in a bearing plate. Often the small diameter rotor shaft of the auger becomes fouled by crop material which wraps around the shaft ultimately inhibiting rotation and sometimes damaging rotor bearings. This is avoided by rotatably mounting a larger diameter auger tube within a recess formed in the bearing plate.

Anti-wrap apparatus

The disclosure is directed to a combine with a unique sealing arrangement between the pivotable feeder housing and the inlet opening. The feeder housing includes axially aligned pivot arms which extend away therefrom to engage a pair of support yokes which permit the feeder housing to pivot vertically. The pivot arms include curved contact plates which sealingly engage at least partly semi-circular resilient closure members on the combine frame to prevent crop material from escaping between the feeder housing and the inlet opening.

Seal for pivotable feeder housing

In a crop harvesting and threshing machine of the type utilizing axial flow threshing and separation there is provided about the upper portions of the rotor casing axial flow inhibiting elements rearwardly of axial flow facilitating elements. The inhibiting elements are arranged in a reverse pattern to the facilitating elements so that crop material transported axially about the threshing and separating rotors is decelerated and deflected into a discharge opening without passing further rearwardly, thus preventing the enwrapping of crop material about the rotatable shafts of the rotor.

Material flow retarders

This invention pertains to a combine of the axial flow type in which rotor means extend longitudinally within the combine in association with concaves, the rotor having in axial alignment, a threshing portion and a separating portion rearward thereof and mounted for coaction with respective concaves disposed beneath the rotor. Tailings which are discharged from the separator section of the rotor and concave normally contain a worthwhile amount of crop material intermixed with waste chaff, straw and the like, and further threshing to separate the crop material from the waste material is effected by a rotatable beater and coacting grate which extend transversely to the axis of the rotor and rearward of the discharge end of the separator portion of the rotor and concave. To adapt the use of the combine to a wide range of different crop materials, the grate for the beater is adjustably supported for movement toward and from the beater by slidable wedge members respectively engageable with opposite ends of the grate, the adjustment being effected externally of the housing of the combine.

Beater grate for combine

A crop handling unit for an axial-flow type combine harvester having an infeed region and tandem threshing and separating regions. An associated conveyor is provided for delivering crop material into the infeed region of the unit whereupon material is urged rearwardly along a generally helical path. Ultimately grain is separated from the crop material and discharged through concaves and grates in the threshing and separating regions, respectively, onto a grain pan. The infeed region is provided with improved means to spread out abnormally thick masses of material during its rearward travel.

Infeed means for axial flow combine

A combine harvester comprising at least one generally cylindrical crop handling unit having tandem threshing and separating sections through which material is advanced along a generally helical path. A conveyor is provided for receiving crop material from a forwardly positioned crop header and delivering it axially into the cylindrical unit. During operation, grain is separated from the crop material and discharged through concaves and grates in the threshing and separating sections, respectively, onto a grain pan which in turn deposits it on cleaning sieves located rearwardly of the grain pan. The clean grain is elevated to a storage tank mounted on the combine while the residue is conveyed rearwardly and expelled onto the field. The grate in the separating section is cylindrical in configuration and comprises a plurality of generally transverse members retained by spaced longitudinal rub bars defining a configuration of apertures permitting discharge of grain over most or all of the circumferential surface of the cylindrical unit. One or more of the transverse members have at least one slightly askew section to assist advancement of crop material along its helical path in the separating section of the combine. A portion of the separation grate extends into the threshing section.
