A mechanical end‐trimmer was developed to cut soybean [ Glycine max (L.) Merr.] plots to a uniform length. It consists of two self‐propelled rotary mowers connected at a desired distance by a horizontal pipe clamped to a frame added to each mower. Two persons are needed to operate the end‐trimmer, one for each mower. The end‐trimmer is driven across plots perpendicular to the direction of the rows, and final plot length is determined by the distance between the mowers. The end‐trimmer works best when lodging is not excessive and when seed formation is not advanced. With this method, two persons can trim approximately 1,500 four‐row plots per day, compared with 400 plots per day by use of hand methods.
