Abstract: A tensioning bar assembly for a drive system of an agricultural machine includes a longitudinal bar having a top end, a bottom end, and a threaded portion. An attachment device is coupled to the top end to attach to a tensioning arm. A compression spring is located around a portion of the longitudinal bar. A first spring retainer engages with and retains a first end of the spring. A first locking nut fits to the threaded portion of the bar and retains the first spring retainer longitudinally in place relative to the bar. The longitudinal bar is rotationally freely coupled to the attachment device to permit free axial rotation of the bar about its longitudinal axis relative to the attachment device, and an engagement head is attached to and located at or proximate the bottom end of the longitudinal bar for engagement with a tool.

Abstract: The skid steer manure spreader attachment includes a main bucket compartment, a cover, and a beater shaft. The bucket, cover, and beater shaft are preferably formed of welded steel. The bucket has an industry standard quick attach plate on the back so it can be quickly attached to any standard skid steer, and is a standard width. A hydraulic motor operates the beater shaft and the cover. The beater shaft has blades angled in two directions. The beater shaft spins forward so the beater blades through manure out of the top of the bucket, above the shaft. The hydraulic motor drives the top sprocket, and a chain drives the bottom sprocket. A tensioner pivots on one screw to allow the user to tension the chain as needed.

Abstract: A drive arrangement is provided which includes: a first and second rotatable members; an endless loop member, extending around the first and second rotatable members, arranged to convey drive from the first rotatable member to the second rotatable member; a first support, arranged to support the first rotatable member and the second rotatable member, having at least one aperture therein; a guide member, defining at least part of a path of the endless loop member between the first rotatable member and the second rotatable member; and a second support, arranged to support the guide member, the second support being connected to the guide member through the at least one aperture in the first support such that guide member is movable, via the at least one aperture, to engage and disengage drive from the first rotatable member to the second rotatable member.

Abstract: A landing gear wheel drive system includes a landing gear strut, a wheel, a drive loop carrier assembly, a drive loop, and a displacement system. The wheel is rotatably attached to the landing gear strut and includes a ring gear mounted to the wheel. The drive loop carrier assembly includes a plurality of toothed pulleys. The drive loop extends around the toothed pulleys to form a continuous loop. The displacement system is connected to the drive loop carrier assembly to selectively engage with the ring gear.

Abstract: A pulley assembly for combining of a wire, may include a groove member having a first guide groove helically threaded in an outer circumferential surface thereof and having a truncated cone shape, and a cylindrical guide pulley selectively combined with a bottom surface of the groove member and having a second guide groove formed on an outer circumferential surface thereof, wherein the wire may be configured to move to the second guide groove of the guide pulley along the first guide groove of the groove member when the groove member combined with the cylindrical guide pulley rotates in a direction.

Abstract: A belt driving apparatus has a motor for generating the driving force, a toothed driving pulley rotating by the driving force, an endless toothed belt wound on the pulley, wherein a first surface of the toothed belt has teeth corresponding to teeth of the pulley and a second surface of the toothed belt is substantially smooth, an auxiliary roller for holding the toothed belt in a gap defined by the pulley and the auxiliary roller, a roller holding unit for holding the pulley and the auxiliary roller to be able to respectively rotate on axes of the pulley and the auxiliary roller and maintaining the gap between the pulley and the auxiliary roller and an urging member for urging the roller holding unit in a direction to the toothed belt around the pulley in order for the auxiliary roller hold by the roller holding unit to provide a tension to the toothed belt.

Abstract: A drive unit preferably employed with a self-propelled lawn mower for driving at least one pair of wheels of the mower. An axle pulley is fixed on the axle of the drive wheels and a directional pulley is rotatably mounted above and in a spaced apart relation to the axle pulley. A drive belt is trained over an upper portion of the directional pulley and about a lower portion of the axle pulley and is then trained about an upper portion of a directional roller. The drive unit has a drive condition and an idle condition in which a portion of the drive belt, between the directional roller and the axle pulley, is in a generally vertical run.
