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 track scraper for removing rubber from a racetrack is provided. The scraper comprises rotating blades that are moved along the surface of the track and that skim off portions of rubber that has been deposited on the track by race cars. The scraper is installed on and powered by a standard garden tractor.

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.

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. During use of the implement when the implement is connected to a tractor, the support stand is in a stowed position adjacent to a side of the implement. When the implement is disconnected from the tractor, the support stand is rotatable outwards from the side of the implement and frontwards toward the front of the implement and rests against the ground to maintain the implement in a generally upright position.

Abstract: A rotary mower with a plurality of cutting blades is provided. The deck comprises two longitudinal baffles that direct grass clippings to the rear of the mower. The longitudinal baffles, in conjunction with right and left side blade guards, form three channels. A cutting blade is disposed within each channel. A lift frame assembly comprises swiveling linkages that allow rotation of the deck with respect to the trailer hitch.

Abstract: A tiller with a removable tine rotor is provided. The tiller comprises a cavity formed by a top deck and end plates. The end plates comprise rotating spindles rotatably attached to the end plates. A gearbox translates rotation from a tractor to one of the rotating spindles. A tine rotor extends between the spindles and rotates to till soil. The tine rotor is releasably connected to the spindles within the cavity, such that the tine rotor is removable from the tiller without disassembly of the end plates.

Abstract: An articulated arm and cutter attachment for mounting on a tractor has a pair of elongated vertical booms pivotally connected to one another at their top ends. The lower end of one of the booms is pivotally connected to a beam extending laterally from underneath the tractor chassis. The other boom has a telescoping lower end on which is mounted a foot which supports a rotary cutter. An upper portion of the beam connected to the tractor is inclined outwardly, and an upper portion of the other beam is inclined inwardly to allow the arm to reach out a substantial distance and extend over obstacles such as fences. Pivoting mechanisms in the foot allow tilting of the supported cutter over a wide range of angular positions. Hydraulic cylinders are provided for carrying out movement of the arm, along with hydraulic fluid lines and controls. Yieldable mounting of the foot provides for breaking away of the cutter upon striking an obstacle.
