Abstract: A self-propelled powered mower (11) and a towed trailing mower (12) are connected together by an adjustable height connector assembly (13). When the powered mower begins to move through a turn, the alignment detector cylinder (60) is required to retract due to the pivoting of the draw bar (21) and its angled support arm about the vertical pivot pin (50) of the connector assembly (13) (FIG. 3). The fluid displaced from alignment detector cylinder (60) causes the rod (56) to extend from height adjustment cylinder (55), thereby raising the forward portion of the towed mower.

Abstract: A twistlock operator for a twistlock mechanism has a drive mechanism with a fixed axis and an angularly displaceable twistlock having a pivot axis normally positioned along the fixed axis. A first actuator is drivingly connected to the drive mechanism for thereby permitting rotation of the first actuator and a second actuator is connected to the twistlock. Each of the actuators is generally rectangularly shaped and each has arcuate side bearing surfaces and the bearing surfaces have substantially equal radii of curvature. A tube is pivotally connected to each of the actuators for drivingly connecting the actuators and thereby causing cooperative rotation of the actuators. The tube maintains driving connection between the actuators even when the twistlock pivots and thereby displaces the pivot axis away from the fixed axis.

Abstract: The present invention relates to a method for transferring harvested tobacco leaves from an amorphous mass of harvested tobacco leaves to a bulk curing container component for subsequent transfer to a bulk curing site. According to the method, the bulk curing container component is positioned adjacent a tobacco discharging end of a tobacco transferring system. The transferring system has the discharging end, a tobacco receiving end opposite the discharging end, and a generally upwardly facing tobacco conveying apparatus for supporting and moving the leaves between the discharging and receiving ends. The amorphous mass of harvested tobacco leaves is supplied to the tobacco conveying apparatus at the tobacco receiving end of the transferring system in such a manner that the harvested tobacco leaves of the amorphous mass are randomly arranged and stacked on top of one another in a generally vertical direction. The transferring system is continuously operated under power such that the transferring system (a) conveys the harvested tobacco leaves from the tobacco receiving end thereof to the tobacco discharging end thereof and then subsequently discharges the conveyed tobacco leaves to the bulk curing container component, and (b) separates the leaves from one another and disperses the separated leaves along the tobacco conveying apparatus as the leaves are being conveyed to thereby reduce the aforesaid vertical stacking of the harvested leaves so that substantially all the leaves being discharged into the bulk curing container component from the discharging end thereof are separated from one another. The present invention also relates to a tobacco transferring system.

Abstract: An electro-hydraulic steering system is disclosed for a wide track steerable vehicle which changes the position of each steerable slave wheel to an optimum angle depending on the angle of a hydraulically steerable master wheel. Controls, including electro-hydraulic steering mechanisms, are provided to cause the steerable slave wheels to turn relative to one another to assume and maintain an optimum turning radius and optimum turning relationship as the vehicle operator maneuvers the vehicle along a desired curved path of travel by hydraulically controlling a master steerable wheel. The system minimizes tire wear, reduces structural stresses in the vehicle, and maximizes traction during turning maneuvers. No conventional tie rods are required and the system may be implemented to permit two wheel steering, four wheel crab steering, and four or more wheel coordinated steering. The system uses a position sensor on the hydraulically steerable master wheel to produce a signal to control the positioning of the slave wheels. The signal is digitized to produce a signal which, when compared to a position signal from a position sensor for each slave wheel, causes each slave wheel to assume an optimum position which is about perpendicular to the turning radius of the vehicle.

Abstract: A straddle crane including four vertical column members, two side beam or torsion members, and at least one header beam member, and having wheel or caster assemblies supporting each vertical column member. The straddle crane is implemented for two-wheel or four-wheel steering and for two-wheel or four-wheel driving with open or closed ends. The structures of the header beam and the side beam members are appropriately selected, and the attachment means therefor to the vertical column members are chosen to accommodate the various forces and stresses occurring on the structure during normal operation over uneven terrain or surfaces. The header beam member is sufficiently flexible to permit movement of the casters over and in contact with uneven terrain without producing unacceptable shear stresses in the header beam member. The torsion beam member defines a closed geometric figure in cross section to provide torsional and bending resistance to the loads applied to the vertical columns.
