Abstract
Abstract A mirror and guide attachment device for a tractor having a trailing cultivator implement towed thereby, includes a mirror assembly mounted on the tractor adjacent and rearwardly of one of the front wheels of the tractor. The mirror assembly is positioned in angulated relation with respect to the ground surface to permit the tractor operator to observe certain rolling shields and cultivator tools on the trailing cultivator implement during the cultivating operation. An elongate guide element is connected with a mounting bracket of the mirror assembly and serves to facilitate guiding of the tractor and trailing cultivator implement during the cultivating operation.

Claim 1
Independent Claim
239 words
A mirror and guide attachment device for a tractor having a trailing cultivator implement towed thereby, said device comprising: a mounting bracket adapted to be attachably mounted on the tractor adjacent one of the front wheels thereof, a rigid generally rectangular mirror frame, means connecting the mirror frame with said bracket for spacing the frame laterally of the tractor body and rearwardly and adjacent one of the front tractor wheels, a rearwardly facing generally rectangularly shaped mirror mounted on said frame, yieldable means interposed between said mirror and the frame to dampen and absorb vibrations thereto, said mirror being disposed in angulated relation and extending downwardly and rearwardly with respect to the surface of the ground, said mirror being disposed at approximately the same height as the upper portion of the adjacent front tractor wheel, a peripheral shield structure secured to said frame and including a pair of substantially flat rearwardly projecting side plates positioned on opposite sides of the mirror and a top plate secured to said side plates and projecting rearwardly from adjacent the top portion of said mirror to reduce glare and protect the mirror from flying objects, a substantially flat cover plate shiftably connected with said mirror frame and being swingable between open and closed positions, said cover plate when in the closed position, overlying and covering said mirror, and when in the open position, being disposed in unobstructing relation with respect to the mirror.
