Abstract: An endless track assembly wherein the weight of an associated vehicle/equipment is supported by the track framework. The track assembly provides a framework having a number of idler rollers and a drive sprocket that mounts to a rotational drive power source. The weight of the vehicle is transferred from a vehicle/equipment support flange that cooperates with a complementary support surface of the track framework and an intermediate bearing liner. The bearing support surfaces cooperate to permit the track frame to pivot relative to the chassis independent of the drive sprocket. The track assembly is particularly adapted to pivoting irrigation systems.

Abstract: An endless track assembly that mounts to a wheeled vehicle. The assembly provides 1) a track suspension having fixed or adjustable, independently biased sets of idler wheels to vary the track contour without affecting track tension, 2) an eccentric bearing housing at a drive sprocket controls track tension, 3) a contoured peripheral edge at the drive sprocket prevents ice and mud buildup, 4) rubber-coated, plastic idler wheels facilitate track movement, 5) a multi-vehicle compatible adapter mounting plate accommodates a variety of vehicles, 6) a rotation limited torsion coupler and/or rotation limiting coupler arms prevent track contact with the vehicle, 7) a locking steering arm coupler prevents loss of steering control, and 8) shaped track lugs and channels clear and direct debris away from the track suspension and drive assembly.

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.

Abstract: Apparatus for selectively coupling a ring gear to the drive train of a race car to effectuate engine start; generally comprising a geared flywheel retaining hub slidably mounted along a slideway between an adapter assembly bolted to the transmission and a geared drive hub bolted to the crankshaft. An intermediate shift actuator pivotally coupled to the adapter assembly and flywheel retaining hub selectively engages/disengages the flywheel from the starter drive and drive train.
