US Patent:

47384638, Apr 19, 1988

Filed:

Feb 24, 1987

Appl. No.:

7/018262

Inventors:

Bernard B. Poore - East Moline IL
Ronald E. Rohren - Moline IL

Assignee:

Deere & Company - Moline IL

International Classification:

B60D 108

US Classification:

280421

Abstract:

An arrangement and assembly for making power connections during the hitching of an implement to a vehicle. The assembly includes mating halves of power connections located on hitch elements of the implement and vehicle respectively. Power connection halves are arranged so that the relative movement necessary between hitch elements of the implement and vehicle to accomplish their connection are also sufficient to cause coupling of the power connection. Alignment of the power connection halves is accomplished by a set of pins which engages a set of holes. The connector halves are resiliently mounted for axial movement in a direction parallel to the axis of the pins. Relative axial movement allows the power connections to be completed and the resilient mounting allows for a degree of axial misalignment.

Abstract:

A mulching mower mechanism, having an inverted U-shaped channel member positioned within the outer periphery of a cutting chamber of a mower deck for generally confining the clippings circulating at the outer periphery of the cutting chamber. The channel member extends generally across the mower deck's discharge outlet for generally diverting the stream of clippings away from the outlet and thereby serves to maintain the clippings within the deck to be re-cut by the blade. The channel member includes an upper and outer wall portions positioned adjacent the discharge outlet for generally blocking the clippings and air within the channel from exiting the discharge outlet. The channel member also includes an inner wall portion which separates the stream of clippings from the relatively clean air circulating within the inner portion of the deck. The discharge outlet is in fluid communication with the inner portion of the cutting chamber for allowing the clean air to exit the cutting chamber via the discharge outlet, thereby maintaining an updraft within the cutting chamber.

International Classification:

E01H 104

US Classification:

134 251

Abstract:

Leaves and other debris arranged in piles along a roadway are lifted by a flail-type rotary cutting device towed centrally behind a tractor. The device includes a containment hood having a forwardly opening throat which is adjustable to conform generally to the size of the piles for receiving the piles and restricting the material from being thrown forwardly from under the hood particularly at the end of a pile. The lifted material is delivered into a receptacle towed behind the cutting device. The rotary cutting device can handle leaves and other debris in states ranging from dry and fluffy to frozen and snow-covered. The tractor and/or additional brushes may be used for preliminary piles sizing and positioning. Brushes may also be added to the machine for additional cleaning action and to help part wide piles.

International Classification:

A01F 1222

US Classification:

130 27T

Abstract:

The feeding system for an axial flow rotary combine in which the separator is disposed generally fore-and-aft includes a dual auger feeder house in which a pair of side-by-side upwardly and rearwardly inclined augers are driven in such directions that a major part of the crop material handled is conveyed in a concentrated high speed stream between the augers and delivered in undershot fashion to be engaged by a separator infeed rotor for transfer downstream to a coaxial threshing section. In the preferred embodiment the infeed rotor and its housing are generally frusto-conical in form, the rotor including a frusto-conical core carrying four equally spaced axially extending tapered feed bars, each bar having a ramp-like cross section, with the rotationally leading edge of the ramp radially closer to the rotor axis than the trailing edge. Each bar carries towards its trailing edge a set of angled material control blades which engage the crop material and contribute to its rotational acceleration and, in cooperation with helically arranged lead members on the inside of the infeed housing, displace the material axially as it is carried around the housing. The feed rotor core is relatively small so that the form of the rotor creates ahead of each feed bar a relatively deep fluted pocket or receiving zone with a converging trailing portion (due to the backward sloping ramp of the feed bar).
