Patent number: 12127498Abstract: A cutting system includes knives attached to a continuously moving belt-type carrier. The carrier motion moves the knives past stationary counterknife fingers which are attached to or uniform with a cutterbar, as the cutting system is driven through a field of crop stalks, which are cut by the interaction between the knives and counterknives. One or more sensing devices produce signals or images related to the condition of the knives when the knives are moving past the sensing devices. A processing unit processes the signals or images and derives therefrom one or more parameters representative of the condition of the knives, and compares the parameters to a reference, to thereby monitor the condition. An agricultural implement such as a combine harvester, can be equipped with the cutting system.Type: GrantFiled: June 16, 2022Date of Patent: October 29, 2024Assignee: CNH Industrial America LLCInventors: Bart M. A. Missotten, Jasper Vanlerberghe, Sam Reubens, Lucas Deruyter, Frederik Tallir, Dré W. J. Jongmans, Sahand Hajshekoleslami, Pieter Van Overschelde

Patent number: 6240714Abstract: A weed trimmer or whacker which has an improved drive belt system. The cutting blades carried by a pulley driven belt have dual cutting edges, so the belt can be reversed after one side of the blades becomes dull. The reversal of the belt allows the other cutting edge to be used, thus effectively doubling the useful life of the belt. The drive system has either a V-shaped belt or a timing belt to reduce the probability of dislodging the belt from about the pulleys, when the cutting blades impinge upon an obstacle.Type: GrantFiled: May 7, 1999Date of Patent: June 5, 2001Inventor: Charles Shear

Patent number: 4418519Abstract: A power lawn mower including a plastic endless chain type cutter assembly having a plurality of plastic whip sticks which produce aeration and suction within the mower casing for improving grass cutting and dispensing. Each whip stick includes an elongated generally flat portion which extends horizontally and merges with a main lift or curved wing portion with the wing portion including a leading impact edge and a trailing lift edge. In operation, the cutter assembly is moved continuously with the lift portions of the whip sticks acting to create an aerating effect for causing a vacuum or suction within the mower casing. This action causes a continuous flow of air to be drawn between the ground and casing for discharging cut grass outwardly through an opening in the casing. The whip sticks are permitted limited pivotal movement upon striking obstacles during rotation. The cutter assembly is supported during powered rotational movement on elongated horizontal portions of a chain guide and support member.Type: GrantFiled: July 29, 1982Date of Patent: December 6, 1983Assignee: J. I. Case CompanyInventor: Mark R. Fralish

Patent number: 4251981Abstract: Two embodiments of mowing machines wherein the cutters are resiliently deflectable to within a guard. In both embodiments, the frame of the mowing machine is connected to a tractor and extends laterally therefrom, the mowers being powered from the power take-off of the tractor by a train of gears, shafts and connecting universal joints. In one embodiment, the mowers rotate about vertical axes with the cutters being rotated on elongated resilient shafts which are also rotated about a common main axis from which they are spaced. The cutters are supported near the ground by holders which permit resilient deflection of the cutters' shafts into guards supported by the mowers when the cutters encounter obstacles or otherwise are subjected to forces which cause them to deflect. In the other embodiment, the cutters are mounted on an endless member such as a chain which runs around laterally spaced apart wheels such as sprockets which are mounted on carrier plates which are connected by a rod which is spring-biased.Type: GrantFiled: October 6, 1978Date of Patent: February 24, 1981Inventor: Cornelis van der Lely

Patent number: 4182098Abstract: An apparatus for harvesting and windrowing of corn utilizes one or more conveyor units swingably mounted to a corn harvesting implement such as a combine or corn picker and has horizontally moving cutting means carried forwardly of the conveyor units. As the implement moves through a field of standing corn, the cutting means severs the cornstalks as harvesting heads on the implement engage the stalk and strip the corn ears from the stalk. The conveyors receive and transport the severed stalks to a cornstalk discharge location between the conveyor units to create a cornstalk windrow along the path of the traveling implement. Corn plant residue, such as leaves, kernels, ear husks and the like, resulting from husking, are discharged from the implement and guided by deflector plates onto the windrow to be retained there for curing and later pickup.Type: GrantFiled: June 10, 1977Date of Patent: January 8, 1980Inventor: Kenneth J. Kass
