Several indirect methods of estimating standing forage mass (FM) are used, but all require a large number of observations for an adequate sample. One popular technique relates FM to height of a disk or plate compressing the forage beneath. This report describes and evaluates a forage estimator "sled" that continuously records the height of a pivoting plate and the corresponding global positioning system (GPS) readings as it is pulled over forage.
