An agricultural mowing machine includes a frame having a coupling device for coupling the machine to a tractor. A carrying arm is pivotally connected to the frame. A first hydraulic cylinder is configured to pivot the carrying arm relative to the frame. A lateral displacement structure is connected to the carrying arm in such a manner that the lateral displacement structure can be displaced relative to the carrying arm in a lateral direction between an inner position and an outer position. A second hydraulic cylinder is configured to move the lateral displacement structure relative to the carrying arm. A mowing unit is connected to the lateral displacement structure. The mowing unit can be moved between an approximately horizontal working position, a raised headland position, and a transport position. The first hydraulic cylinder and the second hydraulic cylinder are connected to each other in such a manner that when the mowing unit is in the transport position and the first or second hydraulic cylinder is actuated by pressurized hydraulic fluid, hydraulic fluid discharged from the first or second hydraulic cylinder is supplied under pressure to the other hydraulic cylinder for pivoting the carrying arm so as to move the mowing unit from the transport position towards the headland position displacing the lateral displacement structure outwards relative to the carrying arm simultaneously.

A height adjustment system for adjusting a cutting deck height of a front mounted cutting deck (50) of a riding lawn care vehicle (10) may include a lever (155) operable by an operator seated on the riding lawn care vehicle, and a height adjustment assembly (150) that is alternately assembled and disassembled during attachment and removal of the cutting deck without any operator interaction other than positioning of the lever.

An agricultural mowing device includes a linkage assembly for attaching to a towing vehicle, and a shaft having an upper end coupled to the linkage assembly for being towed in a field between two adjacent rows of planted matter. The device further includes a primary cutting device mounted to a lower end of the shaft for cutting shorter plant material, and a secondary cutting device mounted near the upper end of the shaft for cutting taller plant material. The device also includes a sensor for sensing a desired cutting height of the planted matter and being communicatively coupled to the primary cutting device or the secondary cutting device, the sensing causing an adjustment along the shaft of the respective one of the primary cutting device or the second cutting device to cut the planted matter at the desired cutting height.

A mower comprising a vehicle, a plurality of cutting assemblies, and an automatic height of cut control system is described. In some aspects, the automatic height of cut control system is configured to automatically change the height of cut for the plurality of cutting assemblies while maintaining the attitude of each cutting blade as the blade moves from a first height of cut to a second height of cut. In some aspects, the cutting assemblies include a variable-length member linked to a four-bar linkage configured to cause a change in the height of cut in response to a change in length of the variable-length member.

A mower frame unit is operatively connected with a tractor device and the mower frame is moveable between a generally horizontal first position and a generally vertical second position. The mower frame is moveable from the first position to the second position via a hydraulic cylinder and piston assembly carried by the mower frame to pivot the mower frame about a transverse axis. The mower frame carries a tensioner assembly that is operatively connected to a lock assembly. The tensioner assembly serves at least two purposes. Namely, to tension a belt operatively connected to mower blade and to maintain a portion of the lock assembly in a locked manner when the tensioner assembly is in a state of tension.

A coupling device, particularly for power-operated machines for agricultural use or the like, includes an oscillating frame which is detachably connected to a hitch assembly of an engine and a movable connection for associating with the oscillating frame the working means of a power-operated machine. The oscillating frame and the movable connecting means are configured to maintain, during use, the working plane of the power-operated machine substantially parallel to the ground, independently of the plane of arrangement of the wheels or of the tracks of the engine.

An agricultural mowing device includes a shaft, a first cutting device, and a second cutting device. The shaft has an upper section, a middle section, and a lower section. The shaft is advanced in a field between two adjacent rows of planted matter. The first cutting device is mounted to the lower section of the shaft. The first cutting device extends laterally from the shaft to a distance covering only a distance between the two adjacent rows. The first cutting device cuts plant matter that grows between the two adjacent rows. The second cutting device is mounted to the middle section of the shaft. The second cutting device extends laterally from the shaft to a distance covering at least a portion of at least one of the two adjacent rows. The second cutting device cuts plant matter that grows in the at least one of the two adjacent rows.

A lawnmower can include a frame; a mower deck; and a connection interface that selectively couples the mower deck to the frame, wherein the connection interface is selectively lockable in an open state to permit installation of the mower deck to the frame, and wherein the connection interface is spring biased to a closed state to lock the mower deck and the frame together.

An apparatus, system, and method of securing attachments to a utility vehicle, particularly a stand-on, zero-turn mower. The apparatus includes an A-shaped mounting assembly having a base with first and second ends and a tubular member extending outwardly from the first end. The tubular member defines a bore that receives a shaft extending from the attachment. The mounting assembly is positioned vertically above a mower deck on an opposite side of the frame of the mower relative thereto. The second end of the mounting assembly and part of the mower deck are secured to the frame using the same connectors. A hydraulic actuator engages a forwardmost end of the assembly and is actuatable to raise or lower the assembly relative to the frame, pivoting the assembly about the connectors. The attachment and mower deck are substantially simultaneously operable to perform separate landscaping tasks while the mower moves across a surface.
