Abstract: A combine harvester (102) drive system switches between a first isochronous operating curve (622) and a second isochronous operating curve (628) of an isochronously governed engine (126) when a load on the combine harvester engine (126) reaches one or more threshold load conditions.

Abstract: A manually guided apparatus for collecting objects, especially fruits and nuts, including a pick-up drum rotatably mounted in the drum chamber of a housing. The drum is disposed approximately transverse to the direction of operation, and is rotationally driven by a drive unit. The housing has a wall section extending over the width of the drum approximately at the level of the outer diameter thereof. A ground support is disposed in the region of ends of the drum. A collection channel provides communication for picked-up objects between the drum chamber and a collection receptacle for receiving the objects. The wall section of the housing and the drum cooperate with one another such that objects are accelerated along the wall section toward the collection channel and are ejected out of the drum chamber along a trajectory into the collection receptacle. A handle is operatively connected to the housing for moving the housing in the direction of operation.

Abstract: A working machine has an operation switching lever mounted on a handle in the vicinity of a handle grip and is arranged to be manipulated by one of the hands of the operator to transmit or interrupt a driving force outputted from the drive source to the working tool. A drive switching lever is mounted on the handle and is arranged to be manipulated by one of the hands of the operator to operate a continuously variable transmission to switch driving wheels from a halt condition to a high-speed advancement condition. A disc is mounted on the handle for undergoing rotational movement relative to the drive switching lever. A control member positions the disc at a preselected angular position relative to the drive switching lever to regulate an amount of pivotal movement of the drive switching lever for adjusting a rotational speed of the driving wheels.

Abstract: A control system for a harvester or similar implement includes a supervisory controller, a set of low-level controllers and a neuro-fuzzy inference system. The supervisory controller employs human expert knowledge and fuzzy logic. The controller monitors the quality of the harvesting process, such as gain loss, dockage, grain damage and the like. Based on the measurements, setpoints for all critical functional elements of the implement are determined. The neuro-fuzzy inference system determines machine settings according to operating conditions and learns from harvester experience. The parameters of the neuro-fuzzy inference system are stored in on-board memory. The neuro-fuzzy system can be used for harvester set-up and as one of the knowledge sources for repeated adjustments during the harvest.

Abstract: A mower having a sub-frame with components including traction motors, wheels and hydraulic pumps for mounting on a main frame as a separate unit to facilitate assembly and repair.
