"The most trouble-free acre counter you can buy," says Gene Aufdenberg, of Aufdenberg Equipment Co., Sikeston, Mo., distributor of the unique Precision Acre Counter from Engler Instrument Co., Jersey City, N.J.

Although designed primarily for planters, the counter can be used to count acres on any wheeled machine simply by attaching it to the axle end of any carrier or ground-driven wheel. A counter-balanced weight inside the meter flips around as the wheel turns, driving a set of calibrated gears. It works traveling forward or in reverse.

"There are two meter models. One is calibrated for a specific machine. The other is a universal model that can be used on any machine with the help of a simple calibration formula," explains Aufdenberg. "The meter reads in exact acres covered. We recommend that it be mounted on a ground wheel, or-a clutch-activated shaft, so it only meters on actual ground worked."

To order, send the width of the machine to be metered and the radius of the wheel to be used, if known.
