Patent number: 4392339Abstract: The windrower, which may be of the mower or mower-conditioner type, is provided with a double windrowing attachment at the rear thereof which may be lowered into a double windrowing mode or raised into a non-operative position for single windrowing. Severed crops are converged centrally of the machine from opposite sides of the cutting path taken by the machine so as to be discharged onto the ground in a single, centrally disposed windrow when the attachment is in its raised position. Actuation of the hydraulic circuitry associated with the attachment to lower the same into its operating position during a next pass around the field causes a conveyor of the attachment to intercept the centrally and rearwardly discharged crop so as to instead divert and convey the same to a laterally outboard position in order that the windrow of that crop cutting pass will be laid adjacently alongside of the previously formed single windrow for the next preceding pass.Type: GrantFiled: November 25, 1981Date of Patent: July 12, 1983Assignee: Hesston CorporationInventors: Marc A.

The frame has at one end a ground-engageable support wheel secured to a rear beam of the frame and at the other end a headstock secured to a front beam of the frame. At least one of the rotors is trailed from the front beam on a linkage permitting the rotor to rise and fall relative to the frame.Type: GrantFiled: December 23, 1977Date of Patent: December 18, 1979Assignee: Massey-Ferguson Services N.V.Inventors: Robert Allely, Alfred J. Bailey

Patent number: 4175367Abstract: A rotary mower is provided with its knives secured to an elastic member and the elastic member is in turn secured to the rotating cutting element, such as a disc, of the mower. This permits the knife to move radially in response to the centrifugal forces on the elastic member. The elastic member preferably has bulged ends which are mounted in housings attached to the cutting element.Type: GrantFiled: December 19, 1977Date of Patent: November 27, 1979Assignee: International Harvester CompanyInventor: Jacques E. Bouet

Patent number: 4166351Abstract: An agricultural do-all machine for performing multiple farming operations including harvesting and loading crops into a tow behind vehicle. The do-all machine, briefly described, comprises a vehicle frame designed around an underbelly conveyor having crop clearance therebetween, and a pair of opposite hand implement support booms carrying belt conveyors which feed crops laterally onto the underbelly conveyor. The underbelly conveyor moves the crop underneath the frame of the machine to another vehicle following behind the agricultural do-all machine.Type: GrantFiled: June 21, 1976Date of Patent: September 4, 1979Inventor: Raymond F. Nienberg

Patent number: 4165596Abstract: Two pairs of cane gatherers are mounted forwardly on a four-wheeled power train, for driving a plurality of constant and variable volume hydraulic pumps, the cane gatherers being provided with gathering chains for holding and moving cane through a pair of cane passageways defined thereby and by sticker and moving chains mounted for endless rotation for guiding two rows of cane to cane toppers and cutters mounted in each passageway, and then to a pair of articulated pilers mounted on the rear of the power train. Cut-cane passageways through the pilers are defined by cane moving chains and rub bars. The pilers in one articulated position lay the cut cane of one row just behind the cut cane of the second row in a continuous transverse windrow across the cut rows and behind the power train and in a second articulated position lay the cut cane across adjacent cut rows. Front wheels are pivotable up to 90.degree.Type: GrantFiled: August 25, 1977Date of Patent: August 28, 1979Inventor: Richard A. Duncan

Patent number: 4160356Abstract: A drive for a mower of the type having a multiple number of vertically disposed drum cutters. The cutting elements are at the bottom of each drum and cut in a horizontal plane. A horizontally disposed pneumatic tired wheel is associated with and acts to impart rotation to each of the drum cutters. External drive is imparted to effect rotation of one of the pneumatic tired wheels. The other pneumatic tired wheels are mounted to have frictional circumferential engagement with each other and with the driven wheel to cause all of the wheels to be driven.Type: GrantFiled: February 6, 1978Date of Patent: July 10, 1979Inventor: Bernard C. Mathews

Patent number: 4157644Abstract: A haymaking machine has at least one, but preferably two, tined raking heads that are driven to rotate about upwardly extending axes from respective mountings. The mountings are connected to the rear of beams that converge forwardly to a right angled junction and a common gear box. Crop passing between the rake heads is thus unobstructed by an overhead frame. A coupling near the junction is connectable to a three point lifting hitch and a pair of spaced apart plates form a pivot connected at one side of the plates adjacent the junction. A retaining element secures the beams in operative positions about the pivot. Each rake head has one, but preferably two, ground supporting cylinders that are positionable around the rake head's axis of rotation. A rear crop guide is pivoted to each rake head near its mounting by a quadralateral linkage that can be set in any one of plurality of guide positions.Type: GrantFiled: April 8, 1977Date of Patent: June 12, 1979Inventor: Cornelis van der Lely

Patent number: 4149543Abstract: The invention relates to a harvesting machine provided with rotary separating means, grain cleaning means located generally below the rotary separating means and at a central location below and between transversely spaced separator discharge openings, and deflector means to convey and deflect crop material from locations generally below and at both sides of the cleaning means rearwardly and inwardly to a central location generally to the rear of the discharge end of the cleaning means. The deflector means are comprised of overhead and lateral deflectors positioned at predetermined angles to one another to progressively change the direction of movement of the discharged crop material from a generally fore-and-aft path towards the central discharge location.Type: GrantFiled: April 3, 1978Date of Patent: April 17, 1979Assignee: Sperry Rand CorporationInventors: Frans J. G. C. Decoene, Jan C. VAN Groenigen

Patent number: 4148175Abstract: A self-propelled combine includes a corn picker head having a corn stalk harvesting and windrow attachment on its underside which includes gathering guide fingers for each row of feeding stalks into a sickle cutter and paddle reel forwardly of augers which convey cut stalks to a centrally positioned discharge, whereby the stalks are dropped onto the ground in a windrow.Type: GrantFiled: April 1, 1977Date of Patent: April 10, 1979Inventor: Kent A. Miller

Patent number: 4126989Abstract: A mowing implement comprises a number of rotating cutter members which are arranged next to each other and above a housing and which are slip-free coupled with each other by means of a driving gear arranged inside said housing, while said cutter members are driven by at least one motor arranged beneath a cutter support of a cutter member. Said motor communicates through a set of ducts with the driving member, for example an electrical aggregate or a hydraulical pump, said driving member being arranged on a vehicle and operating as an aggregate for producing energy.Type: GrantFiled: December 1, 1977Date of Patent: November 28, 1978Assignee: Multinorm B.V.Inventors: Pieter A. Oosterling, Hendricus C. VAN Staveren
