International Classification:

B62D 33027

US Classification:

180 891, 296183, 296 51

Abstract:

A utility transport tractor having a cargo box above the rear axle with the operators platform forward of the rear axle enabling additional seats to be included. To maintain the functionality of a conventional agricultural tractor, the cargo box tail gate and a portion of the cargo box floor can be raised to positions in which they both extend upwardly and forwardly toward the operator. In these positions, the three point hitch at the rear of the tractor is visible to the operator as is typically the case conventional agricultural tractors. The tail gate is mounted to the cargo box for rotation about multiple axes to pivot the tail gate to multiple open positions.

Inventors:

Benjamin Michael Witte - Fairbank IA
James Arthur Nagorcka - Tarrington, AU

Assignee:

Deere Company - Moline IL

International Classification:

B60D 106

US Classification:

280495, 2804161, 280511, 172439

Abstract:

A tractor having a cargo box and an axle mounted hitch ball in which the hitch ball projects upward through an opening in the cargo box floor. This arrangement enables the ball to be used when the cargo box is mounted to the tractor. Furthermore, since the ball is mounted to the axle and not the cargo box, greater load carrying capacity is achieved and the hitch can be used when the box removed from the tractor.

Assignee:

Deere & Company - Moline IL

International Classification:

A01B 63112

US Classification:

172 7

Abstract:

The lower draft link of a tractor three-point hitch includes a sensor to sense draft loads imposed on the draft link by an earth-working implement. Variations in the draft load cause variations in the pressure of the fluid in the sensor from a preselected pressure. A pilot-operated, load control valve is connected to the sensor and is shiftable in response to pressure above and below the preselected pressure to actuate a control mechanism. The control mechanism actuates a direction control valve for directing fluid to and from a hydraulic lift cylinder for respectively raising and lowering the draft link to adjust the implement so as to maintain the preselected pressure and thus maintain the desired draft load.

International Classification:

B62D 1104

US Classification:

180 644

Abstract:

A steering control system for a tracked vehicle includes an engine driven variable displacement steering pump which drives a hydraulic motor. A control system senses steering wheel position, vehicle speed, engine speed and forward/reverse vehicle direction. As a function of these sensed inputs, a control signal is generated and is used to control the swashplate angle of an engine-driven variable displacement pump which drives a steering motor which drives a differential track drive mechanism. The control system also determines a ratio of motor speed to vehicle speed and generates a powerboost signal when the ratio exceeds a threshold value. The powerboost signal is communicated to the engine controller which causes the engine to increase its power output. This modifies the engine fuel delivery curve based on the steering system power requirement and increases the power available for turning the vehicle.
