Self Cleaning Screen Stops Tractor Overheating
Chaff from his pull-type combine that plugged his tractor radiator and caused it to overheat prompted Art Paetkau to design and build his self-cleaning "Clean Screen".
His invention replaces conventional flat and rotary screens. Paetkau says his self-cleaning screen allows 23% more airflow than a conventional screen. While he designed the screen for his tractor, he says it could also be used on combines and swathers.
The fiberglass-mesh screen moves from sidd to side rolling around two vertical shafts like a scroll. A 12-volt electric power window motor turns one vertical shaft rolling the screen in one direction. After the screen rolls up going in one direction, a sensor is activated and screen direction reverses. The screen then rolls onto the other vertical shaft. With the screen moving back and forth, the radiator's always protected from chaff since the self-cleaning action of the dead air space at each end of the screen causes chaff to fall.
The 12-volt motor can be wired to the tractor starter or alternator. It has an off/on switch for shutting the screen off when it's not needed. The screen clips to the side of the tractor in just minutes. The Clean Screen is 31-in. wide and 28-in. tall. It's available to fit most tractors and combines.
Sells for $375 (Canadian). Specify tractor or combine model when ordering. Distributor inquiries are welcome.
