Abstract: A metal replacement latch associated with a plastic closure lid provided for the open upper end of a seed box on a seed planter. The replacement latch includes a metal bracket formed into U-shaped or V-shaped configuration having a pair of legs closely associated with and in engagement with the inner and outer surface of a depending flange provided on the plastic closure lid. The bracket is secured in place by fastening devices and includes an upwardly inclined projection on the upper edge of the inner leg of the bracket which extends toward the seed box to engage a downturned plastic flange on the upper end of a seed box to releasably retain the closure lid of the seed box in closed position. The metal latch replaces a plastic latch provided as original equipment on planter in which flexing of the plastic latch results in breakage of the latch which then requires replacement of the entire closure lid.
