Abstract: A towed, PTO-driven implement is equipped with a jack that can be selectively coupled to the draft tongue either in a working position at a forward region of the tongue, or in a stored position at a rearward region of the tongue. A PTO drive shaft assembly extends over the draft tongue and a pin for releasably connecting the jack to the tongue incorporates a PTO drive shaft assembly support which is positioned so as to support the PTO drive shaft assembly when the jack is in either of its working or stored positions.

Abstract: Components of a crop re-hydration system are advantageously carried on free space of a large square baler. Specifically, a direct-fired steam generator is mounted at a rear location on the baler so as not to transfer heat to a hydraulic fluid supply tank located at a forward location on the baler. Further, the combustion chamber of the steam generator is coupled to a forwardly extending main steam conduit having a length sufficient for ensuring that the water injected into the combustion chamber is thoroughly mixed with hot combustion gases and changed to steam prior to reaching a steam distribution manifold located at a forward end of the baler. A combustion air intake filter is positioned in a relatively clean zone at an elevated location at the rear of the baler. Water tanks are mounted closely adjacent ground wheel axles of the baler so that the weight of the water does not unduly load the baler frame.

Abstract: A steam generator is controlled for applying steam for re-hydrating dry crop during the baling process so as to raise the temperature of the crop being treated with steam by an amount which is within a desired range known to result in bales of crop of good quality.

Abstract: A direct-fired steam generator used for supplying steam for re-hydrating dry crop during baling is controlled so as to produce a desired constant steam temperature output by collecting data from which the heat output of the steam generator can be calculated and using this calculation together with the difference between the actual steam temperature and the desired steam temperature to control the amount of process water sent to the steam generator in order to correct any error in steam temperature. Steam temperature is measured in either one of the steam injection manifolds or in an injection tube coupled to an injection manifold so as to be close to the point of application of the steam to the crop.

Abstract: A direct-fired steam generator body defines a combustion chamber and having an exhaust outlet. A mixing chamber is provided for receiving the exhaust gases from the combustion chamber. A flange joint between an elbow forming part of the mixing chamber and the end of the steam generator body defining the exhaust outlet is designed so as to be cooled by process water coupled to the joint by an injection port provided in one of the flanges.

Abstract: A mower has a pair of cutter heads which are pivotally supported by respective cantilever beams. The cantilever beams are pivotally coupled with a hitch assembly, which in turn is coupled with a traction unit via two lower lift arms and a floatable top link. The floatable top link allows the hitch assembly to float relative to the traction unit during transport. A hydraulic cylinder interconnected between the cantilever beams pivots the beams between a transport position and a working position. Stops on the hitch assembly limit pivotal movement of the beams relative to the hitch assembly.

Abstract: A direct-fired steam generator system is used in conjunction with a baler for providing steam for re-hydrating the crop being baled. Cooling water is pumped through water jackets defined by double walls surrounding the combustion chamber and adjacent components, with this water being routed exteriorly of the water jackets and back to a three-way water control valve provided for normally routing the water back to the cooling water reservoir. The control valve is selectively actuated to couple the returning water to an injector flange for metering the water into an outlet end of the combustion chamber only when a flame is present or soon to be present in the combustion chamber, whereby the water will come into contact with hot combustion gases and be changed to steam which is routed on to be applied to the crop being baled.

Abstract: A self-propelled agricultural vehicle is constructed by assembling the parts of a standard row-crop tractor to the point where the next step is that of mounting the cab to the chassis. At this point, a cab adapter module is mounted to the chassis using the mounting points normally used for mounting the cab to the chassis. The cab, provided in a form without the usual access ladder and fenders, is mounted to the cab adapter module so as to face in a direction opposite to that which it would face if mounted to the chassis. The seat and all controls for operating the tractor remain in the same locations in the cab regardless which direction the cab faces. Minor reconfigurations of hydraulic circuitry and the differential are required for permitting the vehicle to be operated in a forward direction opposite to that for the operation of the standard tractor.

Abstract: A baler for forming large parallelepiped bales is equipped with a crop re-hydrating system for re-hydrating dry crop having a moisture content no greater than 14% with steam during the baling process. In one embodiment, the re-hydrating system includes a steam generator which mixes the steam with hot gas during the steam generation process, with the hot gas/steam mixture being distributed to treat the crop. In another embodiment, hot gas, in the form of hot air, is produced separate from the steam and is joined with it to form a mixture for distribution to treat the crop. In both embodiments, the hot gases serve to insulate and to transfer energy to the gaseous steam (saturated vapor), and are at no more than a minimum temperature required for preventing the steam from condensing prior to being applied to the crop.

A second hydraulic cylinder is coupled between the frame member and the structural member. The second hydraulic cylinder includes a cylinder housing, a ram with a head reciprocally disposed within the housing, a first chamber on one side of the head and a second chamber on another side of the head. A first fluid line interconnects the first chamber of the first and second hydraulic cylinders.

Abstract: A three-point hitch suitable for operation with wide implements is constructed by substituting a pair of flotation actuators for the usual drop links that are normally coupled between a pair of rocker arms and a pair of lower draft links. These drop links are coupled to a hydraulic circuit including, according to one embodiment, individual accumulators for each flotation actuator, and according to a second embodiment, both actuators are coupled to a single accumulator. The accumulator(s) act to cause a pre-selected lifting force to be exerted by the flotation actuators so that a predetermined amount of the weight of an implement mounted to the draft links is counterbalanced, leaving a desired ground pressure being exerted by the implement during operation. When using individual accumulators, a side-to-side weight balance can be achieved since different accumulator settings may be used.
