Patent number: 6718743Abstract: A mower-conditioner includes a header or platform which is equipped with a rotary disc cutter bar having a relatively long length with at least two cutting units being outboard of a central discharge passage where a pair of conditioner rolls are mounted for receiving the cut crop. Aiding in conveying crop to the discharge passage are right- and left-hand sets of three crop converging drums provided at each side of the discharge passage. The outer drums of the two sets are respectively mounted to the top of the right- and left-hand end cutting units of the cutter bar while the other two drums on each side are located behind an inward and rearward extending line that is tangent to the cylindrical path traced by the outer and inner ones of the drums on each side of the discharge passage. In one embodiment, a direct drive transmission is provided, and in a second embodiment a hydraulic motor is provided, for driving the inner two converging drums of each set.Type: GrantFiled: January 28, 2003Date of Patent: April 13, 2004Assignee: Deere & CompanyInventors: Allan Wesley Rosenbalm, Michael Joseph Verhulst

Patent number: 6702032Abstract: Ground fires are contained by an apparatus such as a brush cutter that creates a fuelbreak. The brush cutter (10) includes a rearwardly positioned tractor (11) and a forwardly positioned cutter assembly (12) for cutting fuelbreaks through brush. The brush cutter renders cut brush into smaller pieces that lay substantially on the ground after cutting and that smolder when ignited while lying on the ground. Outboard rectilinear cutting blades (49 and 51) rotate in their forward arcs toward each other so as to urge the cut brush inwardly toward the adjacent blades for re-cutting. The leading skirt (31) of the cutter deck (30) engages and bends the taller brush in the direction of movement of the brush cutter before the lower portions of the brush are cut, thereby inducing the brush to fall in the path of the brush cutter, so that it is overrun by the brush cutter and chopped. The chopped brush is disposed along the path of cut brush, thereby providing a pathway through the uncut vegetation.Type: GrantFiled: October 31, 2000Date of Patent: March 9, 2004Inventor: Robert M. Torras, Sr.

Patent number: 6698170Abstract: A combined mowing machine includes a main chassis designed to be coupled to a tractor, and a plurality of cutting units connected in such a way that they can oscillate on the chassis. Each set of cutting units has a plate support beam mounted between a pair of end plates fixed to the chassis, and a pin integral with the beam. The pin slides in two slots cut into the end plates to allow the movements of the cutting unit. The mowing machine allows the cutting units to oscillate freely in order to follow the lie of the land, as a result of the double-joint oscillation and the forward/back oscillation in the slots.Type: GrantFiled: November 13, 2001Date of Patent: March 2, 2004Assignee: Rotomec S.p.A.Inventor: Paolo Tironi

Patent number: 6688193Abstract: A rotary cutterbar includes a gear case containing a series-parallel set of gears including idler gears and pinion gears for driving the cutting discs of the cutter units. The gear case includes top and bottom walls and the idler gears are each received on a hub including an enlarged upper end located in a hole provided in the top wall and a threaded lower end screwed into a hole provided in the bottom wall. The hubs each have a plastic outer shell encasing a metal insert extending axially within the shell, with the shell forming the sole contact between each hub and the gear case whereby vibrations and shock loads respectively due to gear tooth contact and a cutter knife contacting an obstacle are absorbed by the shell to lessen the transmission of noise and the magnitude of the impact force. O-ring grooves are provided in the plastic shell and receive o-rings for preventing leakage from the gear case through the holes in the top and bottom walls.Type: GrantFiled: January 24, 2002Date of Patent: February 10, 2004Assignee: Deere & CompanyInventors: William Paul Wohlford, Gary Raymond Dustin, Michael Joseph Verhulst, Michael James Mellin

Publication number: 20020053194Abstract: This invention relates to a mower, such as a riding mower, having two side cutting units and a front cutting unit operatively connected to a traction frame. Each side cutting unit can pivot about a substantially vertical axis relative to the traction frame when impact shocks occur on the outer sides of the cutting units. A shock absorber cushions and absorbs such impact shocks, and resists the pivoting motion of the side cutting units, in a bi-directional fashion to be effective during forward or reverse motion of the traction frame. The mower also includes a front cutting unit. The cutting units, both the side cutting units and the front cutting unit, have multiple cutting blades and a single drive motor mounted on the cutting unit for driving all the cutting blades contained on that cutting unit. The drive motor is mounted coaxially on the blade spindle of one of the cutting blades and adjacent blades on the cutting unit are driven by one or more drive belts arranged in straight belt runs.Type: ApplicationFiled: January 8, 2002Publication date: May 9, 2002Inventors: Rex R. Bergsten, Daniel E. Peterson

Patent number: 6349529Abstract: An operating device for an agricultural machine which includes a hitching structure connected to a motor vehicle by use of an upper hitching point and at least one lower hitching point. A second lower hitching point is connected to the device and the hitching structure is movable with respect to the second lower hitching point by use of the device. The device thus makes it possible to bring the agricultural machine from a work position into another position or vice versa.Type: GrantFiled: May 20, 1998Date of Patent: February 26, 2002Assignee: Kuhn, S.A.Inventors: Horst Neuerburg, Fernand Kieffer

Publication number: 20020011055Abstract: A sturdy yet easy to assemble and disassemble T-shaped apparatus for ganging together a plurality of individually powered trail-behind mowers for towing by a tractor mower or other type all-terrain vehicle in cutting grass or similar vegetation. This design includes a tractor drawbar pivotally attached to a vehicle for towing having a pivot pin connected thereto at an opposite end to the vehicle, a center drawbar centrally attached to the tractor drawbar by a pivot hinge for connection with the pivot pin, and which is pivotally attached on either end by a left and a right mower drawbar attachment. The center drawbar also having a rear hitch centrally connected, as by welding, on an opposite side to the pivot hinge to pull additional mowers. The design features at least three pivot points to allow an even cut by a plurality of trail-behind mowers on bumpy, uneven terrain.Type: ApplicationFiled: July 6, 2001Publication date: January 31, 2002Inventor: Donald E. Meyer

Publication number: 20020000081Abstract: An agricultural implement attached to a farm tractor by a three point hitch is used to cut the top of mature cotton stalks, or shred harvested crops or mow turn rows. Knives are mounted on the bottom of vertical shafts which are rotated by belt driven pulleys. The pulleys are driven from a right angle gear box which is driven from the power take off of the tractor. The knives are staggered along either side of a beam traverse to the direction of travel, so that the knives cannot strike other knives as they mow over-lapping swaths.Type: ApplicationFiled: February 22, 2001Publication date: January 3, 2002Inventor: Martin Perry Heard
