Abstract
A threshing system for a combine harvester has first to fourth drums, with a concave beneath the first drum and first and second grates for the second and third drums. The second grate has an engaged position beneath the third drum, and it can be driven from the engaged position, around the third drum, to a disengaged position over the third drum. During this disengagement, a space adjustment system moves the fourth drum to increase a space between the third and fourth drums to enable the second grate to pass through the space.
