Abstract: A track work vehicle includes a track system including a drive wheel supported by an axle housing that drives a continuous ground-engaging track, a saddle assembly that guides the track about the drive wheel and an undercarriage frame that supports one or more idler wheels that guide the track along a ground surface. The track work vehicle further includes a fender assembly that includes at least one fender coupled to the axle housing to overlap a portion of the track.

Abstract: The present invention generally provides a wheel replacing traction assembly which uses, for propulsion, a longitudinally extending traction band disposed around and cooperating with a sprocket wheel, a supporting structure, and idler and/or road wheels. The supporting structure of the traction assembly comprises an independent suspension generally replacing the suspension of the vehicle. In use, the suspension of the vehicle is replaced by a rigid member that can be adjustable in length in a further embodiment. The presence of a suspension in the supporting structure of the traction assembly decreases its unsprung mass.

Abstract: A crawler track chassis is motivated by the reciprocating movement of hydraulic cylinder's piston rod.

Abstract: This invention generally relates to track systems and traction assemblies for use as wheel replacement for normally wheeled vehicles. The track system uses a traction band disposed about a sprocket wheel, idler wheels and road wheels for propulsion. The idler wheels and road wheels are typically pivotally mounted to a support frame, itself configured to be coupled to the sprocket wheel via a support member. The track system also comprises a movement limiting link mounted both to the support member and to the vehicle frame. The movement limiting link limits longitudinal and lateral movements of the track system, such as to prevent contact between the track system and the vehicle.

Two idling wheels on a rear side of the at least three idling wheels are pivoted on a first rocking link, and a longitudinal intermediate portion of the first rocking link is pivoted on the track frame through a first pivot shaft.

Abstract: In order to achieve a solution which assists a farmer in working land in a way which reduces the risk of soil compaction of the land there is, among others, a method of determining a work trajectory to be followed by an agricultural work vehicle. The method includes accessing a soil carry capacity map of an area of land to be worked by the agricultural work vehicle, receiving load data of the agricultural work vehicle so as to determine the agricultural work vehicle load and determining the work trajectory to be followed by the agricultural work vehicle. The work trajectory is determined by correlating the soil carry capacity map and the load data of the agricultural work vehicle, so as to optimize that the area to be worked with low carry capacity is worked with low agricultural work vehicle load.

Abstract: An endless track suspension is comprised of a suspension support beam having an idler wheel assembly connected to a respective one of opposed ends thereof. At least one of the idler wheel assemblies has an endless track binding mechanism. Support wheels are secured to the suspension support beam and project from a lower face thereof. A drive sprocket is secured elevated above the suspension support beam by a support arm. The drive sprocket is secured to a vehicle drive axle by a coupling ring. The drive sprocket, the support wheels and idler wheels constitute an endless track support assembly for supporting an endless track in drivable engagement thereabout. A flexible connection of the drive sprocket support arm and the support wheels absorbs shocks and vibrations transmitted to the vehicle drive axle by the displacement of the endless track over a rough ground surface.

Independent and/or resiliently biased, rocker arms support track idler wheels to induce track flexion and conformance to encountered obstructions.

Abstract: This invention relates to a traction assembly for a vehicle which uses an endless traction band and a plurality of wheels for propulsion. More particularly, the traction assembly comprises a sprocket wheel which has a different size and number of sprocket teeth depending on whether the traction kit replaces the front wheels or the rear wheels of the vehicle. The sprocket wheel of the traction kit can also be configured such that its sprocket teeth are laterally offset.

Abstract: This invention relates to a mower and a tracked implement that convert from one to the other by coupling a mower unit or a tracked unit to a common drive unit. The drive unit is thus used in both products to provide cost savings in the purchase of the equipment. In the tracked unit, a cab for enclosing the operator's station is part of the tracked unit and gets mounted to the drive unit when the tracked unit is coupled to the drive unit. A pair of idlers rotate on pivot axes that are fixed relative to a pivotal idler support that carries the idlers. The pivot point for the idler support is chosen to prevent track elongation when the tracked unit climbs obstructions such as a curb. In the mower unit, a relatively heavy cutting deck is used and spring biased weight transfer arms transfer some of the deck weight to the mower frame.

Abstract: A tracked suspension for a tractor or other work vehicle is disclosed having an endless belt, a belt tensioner, a drive wheel, and a plurality of idler wheels mounted to a suspension frame or idler carriage, the assembly being arranged such that the belt tension provided by the tensioner is absorbed within the frame and is not transmitted to the axle extending from the tractor that drives the tracked suspension. The tracked suspension can be adjusted by loosening or removing mounting bolts that fix the suspension to beams extending from the vehicle, sliding the suspension toward or away from the vehicle, and tightening the bolts. By absorbing the belt tensioning forces within the tracked suspension itself, rather than transmitting the belt tensioning forces to the axle, the suspension can be more easily adjusted without requiring the removal and replacement of the drive axle.

Abstract: A modular endless track assembly which bolts to the wheel of a wheeled vehicle (e.g. pickup truck or ATV). The assembly includes a wheel retainer plate, drive drum, track frame and plurality of idler wheels, track tension adjuster, and vehicle support bracket. The drive drum and idler wheels cooperate with lugs and channels at the track. The support bracket includes an anti-torque coupler mounted between the vehicle and track frame. The coupler centers the track to an equilibrium position and prevents over rotation. The mounting position of the coupler and mounting brackets is varied at the track frame to accommodate front and rear wheel track assemblies. A recurring, W-shaped groove pattern at the track cooperates with the idler wheels to self-clean the track and maintain controlled vehicle steering.
