Abstract: A universal backhoe bucket coupler for a work machine includes a first pair of apertures positioned to be spanned by the mounting flanges of a first style bucket having mounting holes for receiving at least one front mounting pin, a second pair of apertures positioned to be spanned by the mounting flanges of a second style bucket having mounting holes for receiving at least one front mounting pin. A pair of like pivotal spacers is disposed laterally intermediate corresponding outer and inner side portions of the coupler and are pivotable between stowed positions and deployed positions aligned with the first pair of apertures for minimizing lateral bucket motion.

Abstract: A hydraulic system for a loader backhoe work machine in which a propulsion system has a limited output and the pressure relief for the hydraulic actuation system is at a first level for the loader function in which the machine is moved on the ground and a second higher pressure relief for when the backhoe function is being performed.

Abstract: A universal coupler for a backhoe assembly in which a first link is pivotally connected to the articulation joints of the backhoe assembly. Mounting holes for a first and third style bucket with equal pin spacing are provided on the first link. A second link is connected to the first position and is pivotal between a first position in which the mounting holes are exposed and a second position in which the second link covers the holes on the first link and provides the mounting hole diameter and pin spacing for a bucket having a greater pin spacing.

Abstract: A ride control system uses speed, pressure, hand throttle, foot throttle and seat position information associated with a tractor-loader-backhoe to determine when to engage and disengage the ride control system for the tractor-loader-backhoe. Once the ride control system is engaged, the ride control system can be disengaged in response to either an operator command or a measured speed of the tractor-loader-backhoe being below a predetermined speed.

Abstract: A work machine includes a pivotable arm having a first gripping device formed therein, the arm operatively connected to an attachment for securing an object between the first gripping device and the attachment. A second gripping device is removably securable to the arm near the first gripping device, the second gripping device configured to at least partially secure an object between the second gripping device and the attachment.

Abstract: An open retainer cage provides for retaining a threaded female fastener having a non-circular cross section such as a nut adjacent to a surface of a component part for blind-hole fastening. The retainer cage includes a web portion and a plurality of legs extending from the web portion toward the surface of the component part. The plurality of legs are configured to position the web portion parallel to the surface of the component part. At least one of the plurality of legs is affixed to the surface of the component part. An opening is provided between the plurality of legs for receiving the nut within the plurality of legs, the web portion and the surface of the component part. At least one leg is configured to abut the non-circular cross section of the nut for resisting rotation of the nut. The web can also be provided with a tongue extending from the web over an area not occupied by one of the legs.
