Abstract
A side-delivery rake includes a main frame comprising right- and left-hand frame members which diverge rearwardly and are interconnected at their forward ends by a front support assembly and are further interconnected by front, intermediate and rear braces. The intermediate brace is constructed of a cylindrical tubular member and is bent to include opposite end sections that are respectively disposed at right angles to the right- and left-hand main frame members. Identical bell cranks are mounted for rocking about opposite ends of the intermediate brace and include first arms respectively connected, by suspension chains, to identical upstanding brackets fixed to a rake reel support basket extending beneath the main frame, and second arms respectively connected to right- and left-hand lift cranks.
