Abstract: A hay baler scale is provided for automatically weighing hay bales as they emerge from a hay baler. It includes a weighing platform attached to opening of a chute of the hay baler, and a controller with a display. When a hay bale emerges from the baler, it is rotated a quarter turn by the chute and ejected onto the weighing platform.

The controller thus ensures that a reasonably accurate weighing is performed despite the weighing platform being attached to a moving and vibrating hay baler. In a second embodiment, the weighing platform is attached to the top of a chute, so that the bales slide onto the platform without turning.
