In a method for transporting a large milling machine self-propelled by ground-engaging units and comprising a machine frame adjustable in height by means of lifting devices using a tractor unit with a fifth-wheel coupling for a semi-trailer couplable behind the tractor unit as seen in the direction of travel, the following steps are specified: a.) positioning the machine frame of the large milling machine for coupling the large milling machine to the fifth-wheel coupling of the tractor unit or to a trailer using the ground-engaging units and/or the lifting devices of the large milling machine, b.) coupling and supporting the machine frame on the fifth-wheel coupling of the tractor unit or on the trailer, c.) repeating steps a) and b) to establish a mechanical connection between the tractor unit and the trailer by means of coupling the tractor unit and the trailer via the machine frame of the large milling machine, d.) using, as a minimum, the machine frame of the large milling machine with the trailer as semi-trailer.

A reducing element system includes a reducing element having a main body defining a fastener opening, a leading face defined by the main body, and a trailing face defined by the main body. The trailing face includes a pair of mating features equally spaced from the fastener opening and having a generally arcuate cross-section perpendicular to a fastener axis. The system further includes a reducing element mount having a main body defining a fastener opening, a leading face defined by the main body, and a reducing element mount mating feature defined by the leading face. The mount mating feature has a generally arcuate cross-section perpendicular to the fastener axis. The reducing element mount mating feature of the reducing element mount is configured to mate with at least one of the mating features of the reducing element when the reducing element mount is mated with the reducing element.

The present invention relates to a self-propelled material processing and/or handling system for processing and/or handling construction and/or raw materials, in particular in the form of a mobile crushing system, with at least one working unit, which is drivable, by an electric unit drive, with an electric motor, at least one electric travel drive with an electric motor, as well as a control device to control the electric motors of the unit and travel drives. According to the invention, the control device comprises a common frequency converter for the at least one travel drive and the at least one unit drive and provides various parameter sets for the common frequency converter so that the travel drive is actuatable by the frequency converter on the basis of a first parameter set and the unit drive is actuatable by the common frequency converter on the basis of a second parameter set.

A bale processor has a towed body that includes one or two hay bale shredders in the form of a flail drum. The bale processor is self-loading such that bales may be loaded in the processing tubs by a set of rear mounted arms and various conveyor chains. The processor also includes a grain tank, a grain metering system, and a grain cracker, all mounted in series. The grain cracker may have a choice of outputs, including back to the grain tank. The cracked grain is fed into the tub to be mixed with other feed materials, such as shredded straw, and is then discharged to the opposite side of the unit. There may be a feed chopper mounted downstream of the tub, such that the feed chopper receives both the grain material and the shredded hay feed. The feed chopper and the grain cracker operate independently, and may have different setting of size, speed, and weight or volume per minute or per unit of distance travelled. The output may have a curtain assembly to facilitate deposit in windrows.
