Three-point hitch mount systems for connecting an implement to a tow vehicle having two lower hitch arms and an upper link arm are disclosed. The hitch mount systems may include a lift bar configured to be attached to the two hitch arms of the tow vehicle. The hitch mount systems may include a yoke assembly. The yoke assembly includes a forward-facing slot and a downward-facing slot for removably receiving the lift bar.

A ground-contour-following autonomous obstacle avoidance mower for hillside orchards and a control method thereof are provided to achieve multi-angle cutting and low energy consumption in mowing operation through cooperation of a push rod motor and a connecting-rod rotating pair. A connecting rod is arranged and forms a flexible mechanism together with an upper base bearing, a lower base bearing and a base-connecting unthreaded shaft. The flexible mechanism interacts with the push rod motor to achieve ground contour following operation, so that the mower as a whole can conduct ground-contour-following mowing operation on a complex orchard terrain, with a better cutting effect than that of a traditional mower.

A removably attachable adjustable cutting apparatus and method includes a cutting deck, a mounting plate, a main pivot point in the mounting plate and a main adjustable arm with a first end connected with the mounting plate at the main pivot point and with a second end connected with the cutting deck such that the cutting deck is adjustable from a horizontal to a vertical position and positions in between.

A method and apparatus for attaching a forward-mounted implement that may allow pivotal movement of the implement around a longitudinal axis to better maintain proper operational height when operating on uneven or sloped terrain. Further provided, the attachment mechanism of the present disclosure may allow for a secure and safe attachment to an associated tractor or other similar vehicle while simultaneously providing for a reduced production cost and less maintenance requirements.

A mower assembly adapted to be coupled to a hitch of a work machine. The mower assembly has a sub-frame with one or more hitch couplers adapted to be removably coupled to the hitch of the work machine, a mower arm having a first end and a second end, the first end being pivotally coupled to the sub-frame with a pivot pin, the mower arm is pivotable about the first end between a first position and a second position relative to the sub-frame, an arc-shaped rail positioned about the pivot pin for guiding the mower arm as the mower arm transitions between the first position and the second position, and a mower head mechanically coupled to the mower arm at the second end.

A brush cutter may include a back plate and a spindle arrangement with the spindle arrangement abutting the back plate. The brush cutter may also include an angular arm mechanically formed integrally with or mechanically connected to the spindle arrangement where the angular arm is at angle θ relative to the back plate. Angle θ is an acute angle. The brush cutter may also include a mower deck, where the mower deck is mechanically connected to the angular arm and a blade, the blade mechanically connected to the mower deck.

A cutter for use with a mower such as a front of a tractor or skid steer has at least one cutting blade disposed below a cutting deck. A first arm assembly connects at a pivot to the deck and preferably connects to an extension extending forwardly relative to a mounting plate connected to the mower. The pivot is preferably spaced by a portion of the arm assembly from a length of the mounting plate. A roller assembly may be utilized to support the cutting blades above a surface to be cut. A second arm assembly may selectively position the cutting deck at preselected angles about the pivot. The first arm assembly may have curved ribs to allow the cutting deck to be declined to a negative angle relative to the pivot.

An agricultural apparatus including an agricultural vehicle and a number of work units suitable for cutting a standing crop. The work units include a front work unit and two lateral work units located behind and to the sides of the front work unit, each of the work units depositing cut crop as a swath. Each of the lateral work units is supported from a central chassis by a hydraulic system. A plurality of sensors determine a speed of the agricultural vehicle, a speed of operation of each lateral work unit and a relief pressure in the hydraulic system of each lateral work unit. A control unit is configured to receive inputs from the plurality of sensors, compare the values for a desired vehicle speed or speed of operation of the mower unit and adjust the pressure relief in the hydraulic system based on this comparison. The inertia of the hydraulic control system can accordingly be compensated for and the work units are able to follow the terrain contour, resulting in an even cut.
