Abstract: A system may have lights. A light may include a first light source and a first reflector configured to provide lighting for a high-beam mode and for a low-beam mode. The light may include a second light source and a second reflector configured to provide lighting for a cornering light mode. The lighting provided by the first light source and the lighting provided by the second light source may pass through the same headlight lens aperture. A light blocking structure may provide a cutoff pattern that define the illumination pattern of the low-beam lighting and the cornering lighting. One or more additional light sources may be provided to boost the intensity of a hot spot for high-beam lighting.

Abstract: A combine chain and slat crop conveyor includes a plurality of feed drum chain guides. Each chain guide is a generally cylindrical ring which encircles and is attached to the conveyor feed drum and is shaped as a “W” in cross section. Each chain guide includes two outer flanges which extend away from the feed drum surface at an angle, e.g. in a range from 20 to 70 degrees from parallel with the drum surface. The angled outer flanges insure that, as a chain starts to wander out of its path, it will get tighter, which forces it back toward the center of the guide ring. Each guide ring also has an elevated center portion which directly contacts the chain rollers, thus providing a rolling surface for the chain rollers, which puts all relative rolling motion and metal to metal contact between chain roller and roller pin.
