Abstract: A combine harvester has a suspension axle assembly supporting the rear end of the chassis of the harvester. Side frames of the chassis direct loading down to a transverse axle through a pair of suspension devices interposed between the side frames and the axle. The suspension devices are resilient and expandable to cushion the chassis and to provide changes in the fore-and-aft attitude of the combine. The suspension devices may be independently operated to tilt the axle relative to the chassis, and provision is made for shifting the axle longitudinally, side-to-side of the chassis to facilitate turning of the steerable rear ground wheels.

Abstract: A removable cover for attachment to a structure such as a housing. In one embodiment, the cover extends over a mechanical drive system of an implement. The exemplary cover may be used to shield a driven pulley and at least a portion of an associated belt of a lawn mower cutting deck when the cover is attached to the deck. The cover may, at one end, include one or more portions configured to engage the housing. At a second end, the cover may include a resilient lip that, at least in one embodiment, is defined by an opening formed in the cover. The lip may selectively interlock with an anchor attached to the housing to secure the cover relative to the deck.

Abstract: A walk-behind turf aerating apparatus includes two pairs of tine arm assemblies, each assembly having a pair of vertically reciprocating tine arms for driving coring tines into the turf. A tine arm return mechanism includes a gear box for each pair of tine arms, the lower ends of the tine arms being connected to cranks extending from the gear box to reposition the tine arms prior to ground engagement. Stops are provided to limit the tine arm travel. A spring-loaded lifting mechanism permits manual shifting of the tine arm mechanism from a lowered ground-engaging position to a raised transport position. A belt drive with clutch and reduction drive for the wheels also drives the tine arm mechanism with automatic disengagement when the wheels are in the transport position. A handle assembly is connected to the apparatus frame through a pivotal connection including vibration damping elements for minimizing transmittal of vibrations, particularly in the vertical plane, to the handle.

Abstract: A side-ejecting double coring tine includes a pair of vertically depending tine members, each having an upper end portion with a generally rectangular cross-section, a central body portion and a lower end portion having a generally circular cross-section, the central body portion having one side open for the ejection of cores therefrom, the rectangular configuration of the upper end portion providing attachment points for a crosspiece which provides additional structural rigidity to the assembly.

Abstract: A coring tine for use in a turf aerator and the like has an elongated generally tubular body having a core discharge end and a turf penetrating end. The turf penetrating end has a core gripping configuration which, in various embodiments, may take the form of an obround, longitudinal flutes, a generally frusto-conical wall having radially inwardly formed core retaining fingers, or a narrowed neck adapted to improve frictional engagement with a turf core and retain the core within the tine during retraction from a turf surface.

Abstract: In a crop harvesting and threshing machine of the type utilizing at least one axial flow threshing and separating rotor within a generally cylindrical elongate rotor casing there is provided an annular member fastened to a support member surrounding the front portion of the threshing rotor, a guide member fastened to the support member and contiguous with the annular member projecting linearly outwardly therefrom, a ramp section sloping rearwardly and outwardly affixed to the support member adjacent the guide member to direct the crop material from the guide member generally outwardly and upwardly towards the rear of the rotor casing into contact with a transport fin affixed to the top of the casing in an oblique angular relation therewith, thereby promoting the further rearward movement of crop material as it is transported axially about the threshing rotor.

Abstract: Means to tend to dislodge extraneous material from a screen mounted adjacent a cooling radiator for an internal combustion engine such as employed in a grain harvesting combine which develops chaff and dust normally tending to clog said screen, said means comprising one or a plurality of blades extending radially from a cylindrical screen supported for rotation adjacent said cooling radiator and driven by auxiliary means derived from said internal combustion engine.

Abstract: Mobile vehicles and the like having enclosed cabs such as tractors, combines and the like, are provided with air inlet means for the comfort of the operator. The air inlet means are provided with a readily removable filter element and means to support the same by an overhanging forward portion of the roof which extends beyond the windshield of the cab. The filter element is supported by a frame and includes means to raise and lower the frame respectively to support the filter element in upper, operative position and lower, removable position, insertion and removal of the same occurring through an opening adjacent one side edge of the roof of the cab and normally closed by a door, the entire removal occurring exteriorly of the interior of the cab.
