ABSTRACT:
A control element for an agricultural machine comprises a standard lever pivotal about a lever axis through angularly offset positions associated with respective operational levels of the machine. This lever carries a handle remote from the lever axis and centered on a handle axis different from the lever axis and a grip carried on the handle and rotatable thereon about the handle axis between at least one grip end position and an angularly offset grip central position. A grip switch is actuatable by the grip only in the grip end position. A thumb-operable pin is axially displaceable in the handle between an outer pin position and at least one inner pin position. A pin switch is actuatable by the pin only in the inner pin position, and biasing means urges the pin into the outer pin position.
