    Abstract: A flat plate nose frame design for a tractor in which a thick, flat structural plate is connected to and forwardly extends from the conventional frame rails of the tractor. The flat plate nose frame design increases vertical clearance under the hood without raising the hood height or reducing ground clearance. The nose plate is contoured to match the exterior contours of the tractor grill and hood eliminating the need for a separate aesthetic component covering the nose plate. The nose plate features a pair of vertically aligned short-height frame plates extending forwardly along the axis from the deep-section frame rails to increase strength in the flat nose plate without significantly increasing vertical height of the nose plate assembly. The flat plate nose frame is capable of withstanding operational loads as well as supporting a weight package or front-mounted implements.

  • Patent number: 6915873
    Abstract: A suspended drive axle and agricultural tractor having same including a central housing having inboard final drives and left and right axle housing suspended therefrom by upper and lower control arms with axle shafts extending outwardly therefrom to which wheel and tire assemblies are mounted. A constant velocity universal joint is provided between the inboard final drives and the axle shafts. The universal joint having a pair of journal members and a coupling yoke that radially surround the drive and driven yokes of the joint whereby the axial length of the universal joint is minimized to enable the wheels to be located on the axle shafts at 60 inch tread spacing. This allows the drive axle to be used on a row crop tractor without altering the structure of the vehicle from a conventional row crop tractor whereby the characteristics of a row crop tractor are maintained.

  • Patent number: 6758112
    Abstract: In a power transmission arrangement, a working unit includes a hydraulic power unit and a valve unit enclosed in a first bulging portion of a transmission case closer to an upper side or on a top surface thereof and connected with each other along a vehicle lengthwise direction. The first bulging portion is closer to a first lateral side along the vehicle width direction of the transmission case, while a hydraulic pump is located closer to a second lateral side. Hydraulic fluid is drawn from the transmission case, around a lower side of the hydraulic pump, through a suction port thereof, and discharged to a suction port of the valve unit. The hydraulic power unit includes a cylinder tube and piston, extending in the lengthwise direction, and support shaft, extending along the width direction, which is supported by the transmission case and connected to a lift arm.

  • Patent number: 6502840
    Abstract: A suspension linkage for an axle has hard mechanical oscillation stops that move relative to the vehicle frame as the axle travels vertically. The linkage uses thrust bearings to eliminate sideways movement of the axle that causes bounce steer. The linkage is a scissors linkage, having an upper link and a lower link joined together at a center pivot. The hard mechanical oscillation stops are carried by the linkage, as opposed to the vehicle frame, and thus move vertically with the axle.

  • Patent number: 6491129
    Abstract: An agricultural tractor having a rear suspension with draft compensating geometry to control the compression or extension of the rear suspension in response to a draft load. The draft compensating suspension enables the tractor hitch to be mounted on the suspended frame or chassis of the tractor rather than mounting the hitch to a non-suspended beam axle or locking out the suspension during draft work. The draft load is applied to the chassis by a ground engaging implement. The tractive load and torque at the rear wheels are reacted through the side view instantaneous center of the rear suspension. The placement of the instantaneous center will determine the suspension reaction to the wheel load and torque. Locating the suspension instantaneous center on a line of 100% draft-compensation will eliminate the motion of the suspension due to the draft load. If the instantaneous center is located below the 100% draft-compensation line, the suspension will compress under a draft load.

  • Patent number: 6460643
    Abstract: A high clearance farm tractor is capable of accepting different front attachments to enable it to operate as either a swather or a sprayer. The front and rear sections of the vehicle's chassis are connected by an articulating oscillating joint which permits the vehicle's rear wheels to follow the path of the front wheels while turning thereby reducing damage to crops. The oscillating nature of the joint improves traction by allowing the wheels to always have full contact with the ground. A rear mounted engine counterbalances the weight of a front mounted attachment such as a swather head. The mounting of the cab on the front section of the vehicle away from the engine reduces noise experienced by the operator and permits the operator to have a direct line of sight to the operation of the vehicle. The use of active suspension and chemical application rates permit the vehicle to be transported and operated at higher speeds.

  • Patent number: 6454294
    Abstract: A high clearance vehicle includes a walking beam frame and an independent suspension. The frame consists of a main frame, A-shaped frames, a main truss, leg braces, and an axle. Pins which are used to join each A-shaped frame and leg braces to the main truss act as pivot points, as does the pin that attaches the axle to the main frame. Each leg brace may connect to each A-shaped frame by an elastic member to provide the independent suspension. Legs are at each corner of the frame. At the bottom of each leg is a wheel hub mount with a wheel drive assembly operably connected to a wheel for propelling the vehicle. At the top of the front legs are tapered kingpins which carry segmented thrust washers having a knob and receiving portion. A boom having extension arms and spray nozzles may also be attached. The walking beam frame may include a crab steering device which shifts the rear axle off-center so that the vehicle dog legs.

  • Patent number: 6213218
    Abstract: A sod laying self propelled apparatus having a mobile frame mounted on front and rear wheels. The frame has front and rear sections that are articulated to allow the wheels to follow rough terrain. The frame front section has a U-shaped opening to allow receipt of a roll of sod therein without lifting the roll. The frame includes sod lifting arms with a two way hydraulic cylinder to raise the roll once in the roll is in the opening and in such a manner as to generally evenly distribute weight of the roll to each of the wheels. The front wheels are swingable between outside and inside positions relative to front frame arms to change the configuration thereof and include a locking mechanism to lock the configuration. The sod lifting arms are also engageable with a cross bar on a transport truck to allow the apparatus to be rotated relative to the sod raising arms and lifted from the ground for transport.
