  • Patent number: 8117705
    Abstract: A rotary broom mounts upon a slotted plate that pivots upon a double gearbox. The broom has bristles upon an axle within a shield that receives power from a chain drive that receives its power from a driveline from a top gear box. The top gearbox orients in the direction of the chain driveline and delivers its power through an output shaft. The top gearbox joins to a slotted plate that turns in the same direction as the broom. The top gear box receives its power through an input shaft perpendicular to the output shaft. The top gearbox input shaft extends downwardly and becomes the output shaft of the bottom gearbox. The bottom gearbox has an input shaft that connects to a power take off. This rotary broom receives rotational power, rotates it 90° upwardly, then rotates it 90° downwardly and at an angle laterally to drive the broom.

  • Patent number: 8061956
    Abstract: A skid steer bale spear has a single member, or cross tube, to which joins at least one spear and balance spikes. The member then has plates proximate each end welded to the member for connection to a tractor or skid steer loader following the spacing and orientation for the Universal Skid Steer Quick Attach. Additionally, this skid steer bale spear includes a rollback angle to the spear, foot grips, backstops, and detachable spears and spikes. This skid steer bale spear uses less resources, capital, labor, and materials for manufacturing. The member, spear, and balance spikes can be shipped and merchandised in a compact form. At the farm or the ranch, the skid steer bale spear assembles in minutes with hand tools and readily connects to a tractor or loader.

  • Patent number: 7950895
    Abstract: A bucket bale spear bolts together upon a frame, that slips upon the cutting edge of a bucket, and then one bolt secures the frame to the bucket. The frame receives a spear and two balance spikes upon a bracket. A centered tube accepts the spear and secures it with a transverse bolt. The tube provides additional bending resistance for the spear at less weight than a proportional length of spear. The balance spikes also bolt to the frame. The frame, spear, and balance spikes can be shipped and merchandised compactly. At the farm or the ranch, the bucket bale spear assembles readily with hand tools.

  • Patent number: 6543813
    Abstract: A hydraulic hose for use for adapting a skid loader or other apparatus for connecting thereto a hydraulic post driver, the hose assembly includes a fill cap at one end, for connecting with the hydraulic system of the loader, and a fitting at the other end, for connecting with the hydraulic inlet for the post driver. The hydraulic hose has sufficient length, to allow for its looping between these two components, when assembled, and to accommodate any movement of the post driver, relative to the loader, during its application and usage.

  • Patent number: 6349777
    Abstract: A post driver which is mounted to the three-point hitch of a tractor is provided with a support to reduce wobble of the post driver during operation and to facilitate mounting of the post driver to the tractor's three-point hitch. The post driver has a carriage and a ram movable vertically relative to said carriage. The carriage is mounted to a base. The base includes a mount adapted for mounting the post driver to a hitch of a vehicle. A support frame depends from the mount rearwardly of the carriage. The frame has a vertical member and a horizontal member, and generally vertically extending legs at the ends of the horizontal member. The legs are mounted to the horizontal member to be movable vertically relative to the horizontal member. The legs are spaced equidistantly from the carriage of the post driver.

  • Patent number: 5509770
    Abstract: An improved clamp arm and bracket design for a hay handler and unroller apparatus which accommodates a wide range of varying lengths of hay bales is disclosed. The improved clamp arm includes an improved bracket design which is connected to a frame which in turn is connected to a tractor via a three point hitch. Each bracket can be mounted to the frame in one of two possible positions where the bracket is rotated 180.degree. from a first position where the bracket extends inwardly to obtain a second position where the brackets extend outwardly. These alternate positions enable the apparatus to provide for varying distances between said clamp arms by allowing for three possible arrangements of the brackets, namely, both brackets in the first position to accommodate shorter bales, both brackets in the second position to accommodate longer bales, and one bracket in the first position and the other bracket in the second position to accommodate bales of an intermediate length.

  • Patent number: 5452768
    Abstract: A soil tillage implement to be pulled behind a tractor having a conventional frame with one or more furrowing elements depending from the frame or plough share. Each furrowing element has a disc-like coulter, a shank, and a replaceable plough share mounted on the soil engaging end of the shank. One or more gauge wheels, which can be adjusted to vary the height of the implement from the soil so as to adjust the depth of the tillage extending down from the frame. Each gauge wheel employs a counterbalance spring assembly to support the weight of the gauge wheel during adjustment.

  • Patent number: 5016350
    Abstract: Reinforcing device formed from a bent metallic bar stock formed into two legs, having an intermediate bend thereof, inserted into the hollowed end of a tine, such as for a hay loader, or related lift mechanism, and therein reinforcing the tine against shear forces and bending moments. Apparatus is provided for bending the bar stock into the configuration of the reinforcing member, by applying a ram to the bar at that location where the bend is required, and forcing the bar to bend into the formation of a pair of legs, between a pair of guide rollers, through the longitudinal shifting of the ram under excessive force during bending of the bar into its reinforcing configuration.
