Sonar-Activated Header Height Control
You'll like this new automatic height control system that uses sonar to adjust header height instead of mechanical "feelers."
For Deere headers, the Johnson Ultra-Sonic Height Control System wires into standard Dial-O-Matic height control circuits on the combine. An ultrasonic transducer mounts on each side of the head. Maintains header height within 1 1/2 in. of setting, says inventor W.A. Johnson.
"Once installed there's nothing to go wrong. No feelers to break off, no maintenance to worry about," he says.  
The patent pending system installs in about 1 1/2 hours. Sells for $1,695. Will be available for Case-IH and other combines by late 1995.
