Patent number: 7775024Abstract: A rotary mower apparatus comprising a mower deck and two wings, with a plurality of rear wheels mounted behind the mower decks and at least two front wheels mounted ahead of the mower decks such that the mower decks ride along the ground; a floating hitch member is pivotally attached about a vertical and horizontal hitch axes to the front end of the central mower deck and pivotally attached at an opposite end to a tractor allowing the mower decks to float independently. The hitch member contains a mower angle control comprising a bell crank and a hydraulic actuator fixedly attached to a vertical shaft; and a driveline comprising gearboxes, drive shafts, universal joints, and double universal joints arranged such that the mower angle control can pivot the hitch about the vertical hitch axis moving the mower from a minimum offset position to the maximum offset position.Type: GrantFiled: February 3, 2009Date of Patent: August 17, 2010Assignee: Batoche Ag-DesignInventor: Stanley Joseph Boyko

Patent number: 7640719Abstract: A wing-type rotary mower apparatus with a hydraulically powered over-center self-locking wing lift that extends between the central mower deck and the wing mower deck(s) to effect wing movement from a working position to a locked transport position. The lift mechanism comprises a double acting cylinder, a bell crank, and a pair of lift links that are pivotally connected. When the cylinder is retracted the bell crank rotates inward towards the center of the apparatus transferring the movement through the lift links to the mower wing(s). The rotational force on the bell crank about a fixed central pivot point on the central mower deck goes from an outward force reacted to by the cylinder to an inward force supported by the stop seat on the central mower deck; effectively locking the wing(s). The procedure is reversed when the cylinder is extended to return the wing(s) to the working position.Type: GrantFiled: November 15, 2007Date of Patent: January 5, 2010Assignee: Batoche AG - DesignInventor: Stanley Joseph Boyko

Publication number: 20090078511Abstract: A brake mechanism for a caster wheel(s) on an offset rotary mower apparatus wherein a hydraulic line or electric cable is connected at one end to the brake mechanism and at the other end to the tractor for remote control operation of the brake mechanism. The brake mechanism which is attached about the vertical caster axis of the caster wheel allows the caster wheel(s) to temporarily become a fixed wheel(s) when needed, assisting in reducing side draft load on the towing vehicle when the offset rotary mower apparatus is on steep slopes and enabling the offset rotary mower apparatus to be backed-up on the side slope of a ditch.Type: ApplicationFiled: November 15, 2007Publication date: March 26, 2009Applicant: BATOCHE AG-DESIGNInventor: Stanley Joseph Boyko

Publication number: 20080295475Abstract: A castering wheel assembly comprising of a vertical shaft for caster, a horizontal wheel-mount standard, an axle pivotally attached to the standard, two wheels; with one wheel at each end of the axle arranged such that when the wheel assembly is attached to a rotary mower apparatus, the apparatus will follow straight on a side slope. Two embodiments of a mower apparatus comprising a mower deck and two wings, with a plurality of rear wheels mounted behind the mower deck(s) and two castering wheel assemblies mounted ahead of the mower deck such that the mower deck(s) ride along the ground. A trailing or offset floating hitch member is pivotally attached at one end to the front wheel assembly of the center mower deck and pivotally attached at an opposite end to a tractor allowing the mower deck(s) to float with respect to the tractor to follow contours on the ground.Type: ApplicationFiled: November 15, 2007Publication date: December 4, 2008Applicant: BATOCHE AG-DESIGNInventor: Stanley Joseph Boyko

Patent number: 6854250Abstract: A rotary mower apparatus comprises a mower deck with a plurality of rear wheels mounted behind the mower deck and at least one front wheel mounted ahead of the mower deck such that the mower deck rides along the ground on the wheels. A floating hitch member is pivotally attached at one end to a top portion of the mower deck so as to pivot about a substantially vertical mower axis, and is adapted for pivotal attachment at an opposite end to the tractor about a substantially vertical tow axis. The attachment further allows the mower deck to float with respect to the tractor to follow contours of the ground. A drive is operative to transfer power from the tractor to rotate the cutting blade, and a mower angle control is operative to selectively pivot the floating hitch member about the vertical mower axis with respect to the mower deck.Type: GrantFiled: December 17, 2002Date of Patent: February 15, 2005Inventor: Stanley Joseph Boyko
