172272000 | WITH MEANS TO FACILITATE MOUNTING OF IMPLEMENT ON MOTOR VEHICLE | 11 |
20080202779 | Rear Implement Mounting Frame Construction for Tractor - A rear implement mounting frame construction for a tractor is disclosed. The construction comprises a pair of mounting frames attached respectively to right and left sides of a tractor body. Each of these mounting frames comprises a plate member having a plate thickness oriented along the right/left direction. Each mounting frame also includes a case mounting portion that is connected to a rear axle case of the tractor body and a vertical connecting portion formed rearwardly of the case mounting portion which connects a rear implement. A bent portion formed between the case mounting portion and the vertical connecting portion causes the vertical connecting portion to be disposed closer to the tractor body than the case mounting portion. A right/left distance between the vertical connecting portions is set smaller than a right/left distance between the case mounting portions. | 08-28-2008 |
20080296031 | Quick Coupling Mechanism for Tool Attachment - A quick coupling apparatus for coupling a tool to a tool arm comprises a coupler member attached to the tool arm, and configured to engage a mounting bracket extending out from the tool. A wedge is mounted on the coupler member and is movable, when the coupler member and mounting bracket are engaged, from a closed position engaged in a groove on the mounting bracket to an open position where the wedge is removed from the groove. A wedge positioning mechanism selectively moves the wedge to the closed position and the open position. When the wedge moves into the groove and into the closed position, a remotely operated latch control moves a safety latch from an unlatched position to a latched position to prevent the wedge from moving toward the open position. The wedge positioning mechanism can be configured to utilize a single or double acting actuator. | 12-04-2008 |
20090159303 | ROCKSHAFT ASSEMBLY WITH DETACHABLE HYDRAULIC LIFT CYLINDER - A rockshaft assembly includes a support casting having a pair of journeyed bearings supporting a rockshaft for a three point hitch. A piston is connected to a crank on the rockshaft, and a detachable hydraulic lift cylinder is inserted through an opening in the support casting. The detachable hydraulic lift cylinder has a bore partially inside the support casting and partially outside the casting in which the piston moves. | 06-25-2009 |
20120298387 | COUPLING HOOK FOR A LOWER LINK OF AN AGRICULTURAL TRACTOR - A coupling hook forms the end piece of a lower link of an agricultural tractor. The coupling hook has a hook body with a receptacle for a coupling body. The hook body has a receiving chamber in which a safety catch is held. The safety catch can be adjusted between a blocking position engaging over the coupling body and a pulled-back release position. By pressing the coupling body into the receptacle of the hook body, the safety catch can be transferred into an activation position from which it is automatically transferred into the blocking position. In order to increase the operational safety of the coupling hook, the safety catch is operatively connected to at least one cam of an adjustable blocking lever. The cam retains the safety catch in the blocking position, preventing a force originating from the coupling body from being able to adjust the safety catch. | 11-29-2012 |
20120325505 | Coupler With Visibility Window - A coupler for connecting an implement to a machine includes a first mounting structure configured to attach the coupler to the implement. The first mounting structure includes a first actuator including a first cylinder rod extendable relative to a first cylinder body. The first cylinder rod has a first rod longitudinal axis. The first mounting structure also includes a first wedge attached to the first cylinder rod. The first wedge is movable between a retracted position and an extended position by the first actuator. The first wedge includes a first wedge tip insertable into the implement. The first wedge tip has a first wedge longitudinal axis. The first rod longitudinal axis is offset from the first wedge longitudinal axis to form a first opening extending through the coupler adjacent the first actuator. The coupler also includes a second mounting structure configured to attach the coupler to the machine. | 12-27-2012 |
20130133905 | TRACTOR IMPLEMENT SUPPORT LINKAGE - A tractor implement support linkage has a pair of implement attachment links ( | 05-30-2013 |
20130264079 | QUICK-ATTACH ASSEMBLY FOR ATTACHING AN IMPLEMENT TO AN OFF-ROAD VEHICLE - A quick-attach mechanism for attaching an implement to the forward end of a push type assembly which is secured to an off-road vehicle. The quick-attach mechanism includes a front female quick-attach structure on the forward end of the push tube assembly and a rear male quick-attach structure attached to the implement. The front and rear quick-attach assemblies may be quickly selectively coupled together. | 10-10-2013 |

20100307778 | V-Groove Bolted Joint For A Mounting Frame On A Front End Loader - A mounting frame for interconnecting a front end loader with a traction unit includes a base having a proximal end and a distal end. The proximal end of the base is configured for connection with the traction unit. An upright has a proximal end coupled with the distal end of the base. The proximal end of the upright has a projection or a groove, and the distal end of the base has a mating other of the projection or groove. The projection and the groove are each at least partially V-shaped in cross section. | 12-09-2010 |
20110180282 | WRAP AROUND DOZER BLADE HITCH - A frame attachment and link between a materials moving implement, for example a dozer blade, and a vehicle for instance a conventional farm tractor which enables the operator to laterally adjust and raise and lower the dozer blade a substantial distance and yet is relatively easily connected and disconnected with the vehicle. The attachment described herein is a U-shaped frame having a front end including a central pivot attachment point at the base of the U, and several hydraulic attachment points which permit the lateral movement of the dozer blade relative to the vehicle. The U-shaped frame defines an opening which is large enough to accommodate the front frame and body of the of the tractor or vehicle so that the U-shaped frame when in a raised position, encompasses within the opening the front frame and body of the vehicle so that there is sufficient vertical articulation of the dozer blade without interference from the vehicle body. | 07-28-2011 |

20110297406 | FRAME FOR ATTACHING AN IMPLEMENT TO THE WHEELS OF A VEHICLE - A frame for mounting an implement to a vehicle having wheels includes elongated frame members for supporting the implement and drive members that are mounted on the elongated frame members. The drive members contact the wheels of the vehicle and receive a driving force from the wheels. The frame is mounted to the vehicle only on the vehicle wheels, and is able to pivot to follow the steering motion of the vehicle wheels. | 12-08-2011 |
20120006572 | STADIUM GROOMER - The stadium groomer includes a hitch adapted to be pulled by a vehicle. An adjustable hitching mechanism is disposed on one side of the hitch. The hitch includes a base having wheels disposed at the bottom of the base. A grooming frame is pivotally mounted to the opposite side of the base. The grooming frame includes a tank that can be selectively filled with water to increase the weight of the grooming frame. A plurality of plow blades are disposed on opposite sides of the tank in a relatively staggered pattern, and the penetration depth of each of the blades Is adjustable. An adjustable base leveling bar and a pivotal smoothing bar are mounted to the tank on the trailing side thereof. The leveling bar levels the plowed soil beneath the penetration depth of the plow blades while the smoothing bar smoothes the disturbed surface. | 01-12-2012 |
