Abstract
A safety support for maintaining the feeder of a harvester combine, together with its associated header, in an elevated position in case of failure of the usual lift cylinder. A telescopic brace has its forward end pivoted to the feeder and, when in a predetermined extended operative condition, has facilities at its rear end whereby it is supported on the front axle housing of the combine so that it may function under compression to assimilate the weight of the feeder and maintain the latter elevated. In a collapsed inoperative position the brace closely underlies the bottom wall of the feeder in a stored position and is held in such position by a suspension bracket which supports the rear end of the brace. A single anchor pin cooperates with the brace to maintain the latter in its extended position and also cooperates with the suspension bracket to maintain the rear end of the collapsed brace in an elevated position.
