Mechanical System for End-Trimming Soybean Plots¹

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.

Key Words: Glycine max (L.) Merr. • Yield tests • Plot equipment
