An agricultural machine including at least one working tool which can be driven by a drive mechanism which can have a variable drive speed, at least one movable shield which can be moved at least between operational and non-operational positions, and a device for moving the at least one shield, including at least one adjusting actuator and a device for locking the shield. The movement device includes a circuit for controlling the actuator which includes the locking device, which circuit automatically converts a variable input quantity into a control quantity which can adopt a first control value used to prevent the adjusting actuator from being moved out of a first configuration, the input quantity being a value which is a function of or dependent on the drive speed of the drive mechanism or on the working speed of the at least one tool.

Sickle safety guard apparatus comprising an elongated rib laterally bifurcating into a pair of spaced apart longitudinally and laterally extending side wall portions respectively transitioning into a pair of distal, longitudinally and laterally extending, sides wall portions forming a longitudinally and laterally inwardly extending receiving gap between the side wall portions that decreases in separation laterally inwardly for forming respective guiding surfaces laterally inwardly followed by respective pressure surfaces of the side wall portions defining a longitudinally and laterally extending slot therebetween and the respective pressure surfaces radially inwardly increasing in separation to interior terminating ends wherein sickle teeth are received and guided by the guiding surfaces into said longitudinally and laterally extending slot and into abutment with the pressure surfaces while biasing apart the pair of biasing/pressure surfaces for providing a pressure fit between the biasing/pressure surfaces and the sickle teeth.

An agricultural work machine configured to avoid anomalies is disclosed. Agricultural work machines may encounter anomalies, such as obstacles (e.g., tires) or irregularities in the crop (e.g., weeds), which can reduce the quality of the harvested crop. Manually steering the agricultural work machine requires the constant attention of the vehicle operator. Thus, the agricultural work machine is configured to include sensors to generate one or more images (such as images of various regions of the agricultural work machine), an image processing system to process the images and a control unit to avoid the anomalies (e.g., avoid the identified anomalies, to drive in tracks, and/or to stop the agricultural work machine).

Disclosed is a harvesting combine having a cab for an operator, a wheel assembly adjacent to a stairs assembly having a top and a bottom, and an improved stairs assembly for accessing the cab by the operator. The improved stairs assembly in a deployed state is angled outwardly from the top of the stairs assembly. The stairs assembly is rotatably connected about its bottom to both raise the stairs assembly and move its bottom inwardly. The stairs assembly is movably connected by a track assembly about its top so as to permit the top of the stairs assembly to move inwardly and upwardly when the stairs assembly is raised from its deployed state. The stairs assembly may be angled outwardly from the top end of the stairs assembly to an angle from the vertical of greater than 15 and may be rigidly anchored at its lower end.

Aspects hereof relate to a lever-actuated operator protection apparatus. In some aspects, the lever-actuated operator protection apparatus can be raised and lowered by an operator from a seated position, for example, on a terrain working vehicle.

In one embodiment, a method comprising dampening movement of a cab supported by a chassis according to at least one dampening component; receiving plural inputs from at least one sensor and a seat suspension system; and based on the received plural inputs, causing an adjustment to the dampening movement of the cab according to the at least one dampening component.

A bee displacement assembly provided as a mowing machine with a direct drive operated fan housed inside a housing formed with a funnel leading from an interior space of the housing and terminating in a mouth. The funnel tapers both horizontally and vertically to the mouth such that the mouth approximates a narrow, widened slot. Powering the motor turns the drive shaft that in turn operates the fan, creating a concentrated stream of air inside the fan housing that is channelized in the funnel and emitted out the mouth at an area of uncut vegetation immediately prior to cutting by a cutting deck of the mowing machine.

A method for displacing bees from vegetation subject to cutting by a mowing machine having a cutting deck and using a blower assembly affixed to the mowing machine. The assembly is provided as a fan or motorized blower affixed to a funnel. In operation, the fan or motorized blower creates then forces a concentrated air stream into the funnel that then directs the concentrated air stream to an area of vegetation immediately in front of the cutting deck, displacing bees in the area of vegetation prior to cutting. A funnel mouth is oriented so that the emitted air stream is at least as wide as the cutting deck, and multiple blower assemblies or larger funnel attachments may be used to accommodate larger cutting decks. The method includes selective actuation of the blower while operating the mowing machine.
