Patent number: 5138756Abstract: A control mechanism for operating a backhoe is disclosed wherein the controls are adaptable to be configured in a selected one of a two lever system, a three lever system, or a four lever system. The control mechanism includes a first pivot axis on which the control levers are pivotally mounted and a second pivot axis on which a series of bell cranks are pivotally mounted. Various linkages interconnect the control levers with the bell cranks, and the bell cranks with hydraulic valve spools in a manner in which the valve body does not have to be reconfigured depending upon which control system is utilized. The control levers are configured with a pivot casting having a bent control rod threadably received therein, the position of which is fixed by a lock nut permitting the control handle to be positioned in the orientation desired by the operator.Type: GrantFiled: May 10, 1991Date of Patent: August 18, 1992Assignee: Ford New Holland, Inc.Inventors: Russell I. Johnson, Garry L. Ball, John O. Steinkamp

Patent number: 5125787Abstract: A tractor-loader-backhoe is disclosed wherein the loader mechanism is mounted on the frame of the prime mover by a tapered pivot pin having a fastener extending entirely through the axis of the pivot pin to effect a clamping load operable to seat the tapered pivoted in the conical hub affixed to the frame of the prime mover to assure a firm fastening of the loader mechanism on the prime mover. The backhoe mechanism is provided with a transport lock remotely accuatable from the operator's cab mounted on the prime mover and incorporating a locking pin having a concentric spring mounted thereon to urge the pin out of engagement with the frame whenever the transport lock is disengaged to permit operation of the backhoe mechanism. The boom and dipper members of the backhoe mechanism are constructed from a pair of opposing C-shaped channels having inwardly directed legs centrally located within the boom and dipper members.Type: GrantFiled: February 21, 1991Date of Patent: June 30, 1992Assignee: Ford New Holland, Inc.Inventors: Garry L.

Patent number: 5088881Abstract: A tractor-loader-backhoe is disclosed wherein the loader mechanism is mounted on the frame of the prime mover by a tapered pivot pin or sleeve having a fastener extending entirely through the axis of the pivot pin or sleeve to effect a clamping load operable to seat the tapered pivot pin or sleeve in the conical hub affixed to the frame of the prime mover to assure a firm fastening of the loader mechanism on the prime mover. The backhoe mechanism is provided with a transport lock remotely actuatable from the operator's cab mounted on the prime mover and incorporating a locking pin having a concentric spring mounted thereon to urge the pin out of engagement with the frame whenever the transport lock is disengaged to permit operation of the backhoe mechanism. The boom and dipper members of the backhoe mechanism are constructed from a pair of opposing C-shaped channels having inwardly directed legs centrally located within the boom and dipper members.Type: GrantFiled: February 19, 1991Date of Patent: February 18, 1992Assignee: Ford New Holland, Inc.Inventors: Garry L.

Patent number: 5015148Abstract: A mounting frame for use with a tractor loader is disclosed wherein the main support arms extend generally linearly from the rear pivot mounting thereof with the tractor to the front pivot mounting with the loader bucket. The thickest portion of the main support arm is positioned immediately rearwardly of the transverse torque tube interconnecting the laterally spaced main support arms. Each main support arm decreases in size from this intermediate portion toward the forward and rearward pivots. The main support arm is generally symmetrical about a straight line interconnecting the forward and rearward pivots.Type: GrantFiled: August 21, 1990Date of Patent: May 14, 1991Assignee: Ford New Holland, Inc.Inventors: Russell I.
