Abstract: A header for a combine harvester has a primary implement, a secondary implement and a link that is connected with the secondary implement. The header further has a lifting device with a slide element that is formed and connected with the link so that a translational movement of the slide element causes a lifting of the secondary implement relative to the primary implement.

Abstract: A header for a combine harvester has a primary implement and a secondary implement with a roller unit. The roller unit has a frame element, an outer roller set with a rotatably supported roller and a central roller set with a rotatably supported roller. The central roller set is guided on the frame element to be lowerable relatively to the external roller set.

Abstract: A loading and transport apparatus for an agricultural header or implement that comprises a primary tool and a secondary tool, comprising a guide frame. On the guide frame is arranged a first support device having a first rest surface for movably holding the primary tool. On the guide frame is further arranged a second support device having a second rest surface for movably holding the secondary tool. A coupling element is arranged to the first support device, wherein the coupling element connects the first support device to the second support device. To the guide frame is arranged a support element, which contacts the second support device, wherein the coupling element and the support element are designed and arranged such that a movement of the first support device in a first direction along the guide frame effects lifting of the second rest surface.

Abstract: A header assembly for a harvesting machine comprising a primary cutter head for cutting the crop, and a feeder for feeding the cut crop into the mouth of a crop processing mechanism. The assembly further comprises a secondary scissor-action cutter head trailing behind the primary cutter head for cutting stalks left behind by the primary cutter head, the secondary cutter head coupled to the rear of the header and supported by ground engaging rollers. The rollers include at least one support cylinder having a circumferentially discontinuous ground engaging outer surface operative to perform a preliminary processing of at least one of the crop residue and the soil.

Abstract: A modular agricultural cutting unit for a harvester has a plurality of cutting modules each having a horizontally arranged shaft drivable in rotation and a plurality of cutting elements arranged on the appropriate shaft for cutting crop material, wherein the shafts of the cutting modules are arranged to not overlap in the cutting width of the cutting unit.

Abstract: A multi-purpose turf machine (100) used primarily as a triplex turf mower includes a system for attaching an “operating unit” (e.g., a turf cutting unit) to a traction vehicle (102); and for moving the operating units, e.g., a pair of front cutting units (108a), between a working position and a transport position, the system utilizing a single actuator (224) to provide both vertical lifting as well as “wing-like” pivoting motion. The attachment system includes a female A-frame member (132) attached to the front cutting units (108a) and a mating male A-frame member (202) movably connected to the frame (101) of the vehicle (102). The machine (100) additionally includes a belt drive system to power the cutting units (108). The belt drive system provides correct belt tension between a driving pulley (230, 236) located on the vehicle (102) and a driven pulley (124) located on the end of each cutting unit (108) when the cutting units are in the working position.

Abstract: In an internal combustion engine with at least two groups of cylinders of which each has an exhaust pipe with a catalytic converter and of which one group can be shut down so that it is inoperative during part-load engine operation, the exhaust pipes are joined downstream of the catalytic converters by a common pipe section, and vacuum generating means are provided for subjecting the exhaust pipe of the inoperative cylinder group upstream of its catalytic converter during part load operation when the one cylinder group is shut down to vacuum for pulling exhaust gas from the common pipe section into the catalytic converter of the inoperative cylinder group.
