Abstract: An air powered landing gear supports a front end a trailer when it is deployed. A cylindrical rod is secured to an underside of the trailer, and a collar assembly rotates around the rod. A leg assembly is rigidly affixed to and extends downwardly from the collar assembly. A pneumatic cylinder extends between the trailer and the leg assembly and is configured to rotate the landing gear from a deployed position, wherein the landing gear supports the front end of the trailer, to a stowed position, wherein the landing gear is rotated upwardly toward the trailer.

Abstract: A trailer chassis is formed from a first main beam disposed diagonally to a longitudinal axis of the trailer and a second main beam disposed diagonally to the longitudinal axis of the trailer. The second main beam crosses with, or is intertwined with, the first main beam, to form a chassis in the shape of an X. The X-shaped chassis has a tighter turn radius and greater resistance to deflection and fracture than conventional trailers that have two main beams extending parallel to one another down the longitudinal axis of the trailer.

Abstract: A trailer has a main frame with a neck portion on its forward end. A pivot fifth wheel is rotatably affixed to the forward end of the neck portion. The pivot fifth wheel releasably attaches to the fifth wheel of a towing vehicle. An axle frame is rotatably affixed to the rearward end of the main frame, and rotates with respect to the main frame. The pivot fifth wheel and the axle frame are configured to pivot and move the main frame upwardly a vertical distance.

Abstract: A post hole digger couples to the power take-off (PTO) shaft of a tractor and uses rotation from the PTO shaft to rotate an auger. A top support arm rotatably coupled to the top pin of the tractor's three point hitch supports the gearbox that translates rotation to the auger. A support frame extends upwardly from the right and left lift arms of the three point hitch and inwardly to support the top support arm from beneath. The support frame is shaped generally as an inverted “U,” with space created between the right and left lift arms to prevent interference with the rotating shaft that translates rotation from the PTO shaft to the gearbox. A shield coupled to the gearbox covers the moving parts of the joint between the rotating shaft and the gearbox and protects users during use of the auger.

Abstract: A stump cutter comprising a cutting head that rotates about a generally vertical axis is provided. The cutting head comprises a plurality of cutting blades that are angled with respect to a backing plate of the cutting head. At least two of the plurality of cutting blades are further angled radially with respect to a center of the cutting head, such that the centermost edges of the cutting blades extend further into a stump than the outermost edges of the cutting blades. The stump cutter is powered solely by the PTO of a tractor.

Abstract: A trailer chassis having a lower frame or roller bogie undergirding an upper frame may be extended to adjust the length of the trailer chassis in response to the weight of a shipping container being transported. The roller bogie is slidably coupled to the upper frame along two side support tubes which have locking assemblies to allow for the locking of the bogie to the upper frame with a dual sided, retractable locking pin. Each side support tube includes a plurality of opposing rollers embedded within each tube and has an upper rotating surface that protrudes through the top surface of the support tube so that as the bogie may be freely moved backwards or forwards relative to the upper frame and can be locked into an extended or retracted position. The movement of the bogie does not affect the position of a shipping container locked onto the chassis because the bogie movement is completely under and independent from the flatbed portion of the chassis supporting a shipping container.

Abstract: The gearbox lock mechanism for a post bole auger has a collar coupled to a lower end of a right angle gearbox, the collar rotatable upon operation of the gearbox. The collar comprises a semi-circular outer edge and a fiat side. A male-threaded nipple extends from the collar and threads onto the auger shaft. A lock bar is coupled to the gearbox and acts as a positive lock to lock the collar in place for removal of the shaft from the gearbox. The lock bar is rotatable from a locked position whereby the lock bar is aligned with and contactable with the flat side of the outer edge of the collar, to an unlocked position whereby the lock bar does not contact the flat side of the outer edge of the collar.

Abstract: A rotary mower has a lift frame comprising swiveling linkages that allow rotation of the deck with respect to a three point hitch. The lift frame further has a pair of angled legs rotatably affixed to the lift frame, each angled leg having an upper end and a lower end, the lower ends rotatably affixed to pivot brace brackets rigidly affixed to the deck. Each angled leg of the lift frame is rotatably affixed to one or more pivot bars near the upper end of the angled leg. Each pivot bar extends upwardly between the angled leg and an upper end of the lift frame. A shield covers the pivot bars to protect the users.

Abstract: A tractor-based box blade is used to move and condition soil. The box blade has a plurality of rippers, which are forwardly- and downwardly-extending shanks terminating in relatively narrow teeth that extend into the ground. Each ripper is deployable to extend into the ground independent of the other rippers, and each ripper is stowable away from the ground independent of the other rippers. At least one scraping blade is disposed behind the rippers for smoothing soil.

Abstract: A trailer has a rear gate that is closeable in a generally vertical orientation and openable in one of three orientations: the gate swings downwardly open to be used as a ramp; swings open to the left side, rotating around left hinges; and swings open to the right side, rotating around right hinges. Removal of pins from an upper left and upper right set of hinges enables rotation of the gate in the downward position. Removal of pins from the upper left and lower left set of hinges enables rotation of the gate in the right position. Removal of pins from the upper right and lower right set of hinges enables rotation of the gate in the left position. Removal of all of the pins allows the gate to be completely removed from the trailer.

Abstract: A support stand for an implement such as farming equipment is provided. During use of the implement when the implement is connected to a tractor, the support stand is in a stowed position adjacent to a surface of the implement. When the implement is disconnected from the tractor, the support stand is rotatable outwards from the surface of the implement and downwards towards the ground and rests against the ground to maintain the implement in a generally upright position.

The lift frame further has a pair of angled legs rotatably affixed to the lift frame, each angled leg having an upper end and a lower end, the lower ends rotatably affixed to pivot brace brackets rigidly affixed to the deck. Each angled to of the lift frame is rotatably affixed to One or more pivot bars near the upper end of tile angled leg. Each end pivot bar extends upwardly between the angled leg and an upper end of the lift frame. A shield covers the pivot bars to protect the users.

Abstract: A rotary mower has a concave cutting deck. The deck comprises three curved plates welded to two longitudinal supports. Concavity is provided in the longitudinal and transverse directions. The lift frame assembly comprises swiveling linkages that allow rotation of the deck with respect to a three point hitch. The lift frame assembly further comprises a pivot brace on the top of the frame for further rotation of the deck.

Abstract: A weed cutter that may be pulled behind a tractor is provided. The weed cutter has plurality of cutting blades that rotate when acted upon by planetary gears rotating around a central sun gear. A planetary gearbox assembly with a cloverleaf shape rotates partially around fence posts and other objects to cut weeds growing around the objects.

Abstract: A support stand for an implement such as a tiller is provided.
