Abstract: An excavator drive system wherein one of a pair of propulsion motors shares one of a pair of inverter power sources with another of a pair of motors dedicated to crowd and hoist motions. A pair of non-volatile bi-state switches, triggered under control of a controller, allow sharing of inverters between hoist and propel 1 motors. Another pair of switches allows inverter sharing between propel 2 and crowd motors. Each pair of switches enables change over and power transfer from one of the paired motors to the other motor. The bi-state switches enable quicker transfer of power between motors than transfer switches employing external motor-powered mechanical transfer linkages. Bi-state transfer switches also maintain transfer coupling status in the event of power failure to the switch actuators, allowing an excavator operator to continue the drive function in operation prior to the switch power failure.

Abstract: A mechanism for controlling raised and lowered positions of a hitch-mounted implement includes a rotatable control knob coupled to a transducer, e.g., a potentiometer, for movement between first and second positions representing the raised and lowered positions, respectively, of the implement. The control knob has a button for locking the mechanism in the implement-transport position and for other purposes. A position knob includes a tang-like stop for limiting rotation of the control knob toward the second position. The position knob thereby "sets" a lowered position of the implement which is somewhat above the lowest possible position of the implement. The position knob may be rotated to locate the stop anywhere between two barriers which set the overall limits of travel of the control knob. Most preferably, the position knob is clamped between a barrier member and a console surface and is frictionally inhibited from rotating.

Abstract: A working vehicle includes an engine in the rear of a passenger seat, and a working machine vertically movably disposed in the rear of the engine, wherein an upper end of the working machine which is lifted to the highest position is set lower than an upper end of the engine. As a result, a ventilation in the vicinity of the engine is improved and a cooling effect of the engine is enhanced. Also, a maintenance of the engine can be conducted without being interfered by the working machine. Further, with this arrangement, a center of gravity of the working machine is low, thereby enhancing a stability of the working vehicle, and a driver or a passenger of the vehicle can visually check backward much easier.

Abstract: An improved frame for a drawn agricultural implement, such as a planter, includes a telescoping main frame. The main wheel set is mounted to a sliding carriage to support the central main frame, and may be moved between a forward and a rear position. As the main frame extends, the wing sections fold forwardly. When the wing sections in the illustrated embodiment are completely folded, hydraulic cylinders slide the main wheel set forwardly so that the down load on the hitch is reduced for road transport. Conversely, during the unfold cycle, the hydraulic cylinders return the wheel set to the rear position, and the wings are then extended (i.e., unfolded) for field use.

Abstract: A hydraulic downpressure system for use on no-tillage seeders allows for a constant downward force to be applied on seeding tools operating in highly variable soil surface conditions in order to keep a uniform seeding or planting depth. Raising and lowering of the seeding units can also be achieved with this hydraulic system. A double acting hydraulic cylinder is principally used having its rod end connected to one or two seeding units. A hydraulically operated two-way mode selection valve provides system shifting between both modes involved. The first mode is used when transporting the seeder on roads and to operate the seeding tools in the field. Control is then provided by a three-way directional valve mounted to an external hydraulic power supply, such as an agricultural tractor. Raising and lowering of the seeding tools can be achieved when operating in this mode. A second mode is involved when the seeding tools are working into the ground to sow seeds.

Abstract: A partial width seeding attachment includes electronically controlled solenoids which activate hydraulic flow control valves connected to the hydraulic cylinders on respective implement sections. Switches in the tractor cab control the rockshaft of one or more selected sections independently of the other sections to raise the openers on the selected section or sections from contact with the soil. An electronically activated flow reversing valve is connected between the source of hydraulic fluid under pressure and the lift cylinder for each of the sections. Activation of a selected valve after the selective control valve on the tractor is moved to the normal field working position pressurizes the side of the cylinder that raises the openers on the section. The remaining cylinders operate normally to maintain preselected down pressure on the other openers. A master raise switch provides implement lift independent of the position of the individual rockshaft control switches.
