Abstract: A rotary cutter is provided that has a center section and at least one wing section pivotally connected to the center section. The rotary mower is transformable between a transport position, with the wing section pivoted upwards, and an operating position, with the wing section pivoted downwards. A lifting assembly is provided between the center section and the at least one wing section to pivot the wing section. The lifting assembly can have a lifting actuator, a lug provided on the lifting actuator, a pivot member, and a pivotal connection between the lifting actuator and the pivot member. A guide member can run adjacent to the lifting actuator and have a guide channel for receiving the lug when the wing section is pivoted upwards into the transport position.

Abstract: An agricultural implement has a center frame supported on center wheels and right and left interframes are pivotally attached to corresponding ends of the center frame about wing pivot axes. Right and left wing frames are pivotally attached at front inner ends thereof to front ends of corresponding interframes about front interframe pivot axes. Rear inner portions of the wing frames are movably attached to corresponding interframes. Latch mechanisms selectively lock the rear inner portions each wing frame to rear portions of the corresponding interframes. A center actuator pivots the center frame such that the frames move from an operating position extending rearward to an initial transport position extending upward where the interframes and wing frames can pivot rearward about the upright wing pivot axes. The front interframe pivot axes are oriented perpendicular to the wing pivot axes.

Abstract: An agricultural implement has a hitch frame, a center frame pivotally attached rearward of the hitch frame about a hitch pivot axis. Wing frames are pivotally attached to ends of the center frame and a center actuator is pivots the center and wing frames from a rearward extending operating position to an upward extending transport position. Caster wheels are pivotally mounted on front sides of the wing frames about caster and transport axes. In the operating position, the caster axes are oriented vertically and the transport axes are oriented horizontally, and in the initial transport position, the caster axes are oriented horizontally, perpendicular to the hitch pivot, the transport axes are oriented vertically, and caster wheel actuators pivot the caster wheels 90 degrees about the transport axes to align the caster axes with the hitch pivot axis. The caster wheels support the wing frames in both operating and transport positions.

Abstract: An implement includes a hydraulic control to move rear wheels upward and downward. A hitch frame has a rear end pivotally connected to a front of the implement's frame about an upper hitch pivot axis and a front end connectable to a tractor drawbar. A tension link has a rear end pivotally connected to the front end of the implement about a lower hitch pivot axis located below and parallel to the upper hitch pivot, and a front end movably mounted to a front of the hitch frame. A front hydraulic cylinder moves the front end of the tension link forward and rearward. The hydraulic control activates the front hydraulic cylinder to move the tension link rearward as the rear hydraulic cylinder moves the rear wheels upward with respect to the implement frame, and to move the front end of the tension link forward as the rear wheels move downward.

Abstract: A rotary mower apparatus for applying liquid chemical to vegetation has a rotating drive shaft extending downward through the deck, and a plurality of blades extending horizontally from the drive shaft. A blade ring extends downward from a bottom surface of the mower deck and is configured such that a bottom edge of the blade ring is located above a path of a middle portion of the blades, and a plurality of sprayer nozzles extend downward from the bottom surface of the mower deck inside the blade ring. A chemical source is operative to deliver pressurized liquid chemical through the chemical conduits to each sprayer nozzle.

Abstract: A hitch extension apparatus for attaching an implement with a pto driven drive shaft having front and rear universal joints to a tractor drawbar. The apparatus comprises a first member adapted for attachment to the tractor drawbar by insertion of a drawbar pin through the drawbar such that the first member is fixed with respect to the drawbar. An extension member is pivotally attached to the first member about a horizontal pitch axis oriented perpendicular to the travel direction, and about a horizontal roll axis oriented parallel to the operating travel direction. The extension member defines a pivotal attachment location rearward of the draw pin hole adapted for pivotal attachment of the implement about a vertical yaw axis located equidistant from the front and rear universal joints when the drive shaft is connected to the tractor power take off. The pitch axis can be located forward of the yaw axis, and forward of the draw pin hole in order to reduce bending forces on the drawbar.

Abstract: A harrow apparatus comprising an implement frame and a harrow section attached to a mounting assembly extending rearward from the implement frame such that the harrow section engages the ground surface. The mounting assembly is movable upward and downward to move the harrow section down and up. The mounting assembly comprises a beam extending rearward above the harrow frame, and front and rear arms pivotally attached at upper ends thereof to corresponding front and rear beam pivot axes located on the beam. The front arm slopes downward and rearward to a lower end thereof that is pivotally attached to the harrow frame at a front frame pivot axis, and the rear arm slopes downward and forward to a lower end thereof that is pivotally attached to the harrow frame at a rear frame pivot axis located rearward of the front frame pivot axis.
