1989 – First Automation System – Pneumatic irrigation

With the first Padman watertight door, John set out to make a good thing great with automation.


Years before telemetry or the common usage of electronics in the field, John developed a pneumatic automation system that could open the Padman watertight door.


An airline was run the length of the field and when the water reached the opening, the increased air pressure in the line triggered the door release mechanism.
