Buzzer Sounds When Grain Tank Is Full

Buzzer Sounds When Grain Tank Is Full COMBINES Accessories 19-1-13 When John Freeland, Dalton City, Ill., mounted a grain tank extension on his Deere 6620 combine, he was no longer able to see when the tank was full. He solved the problem by mounting a homemade ; monitor on the extension that causes a buzzer and light to go on inside the cab when the tank and extension are full. Freeland used a 6 by 12-in. piece of light gauge sheet metal to make a hinged flap that mounts on a length of angle iron. The angle iron bolts to a hinged 2 by 4 board at the top of the extension. As grain pushes against the flap, it closes a spring-loaded switch mounted on the angle iron. The switch is connected to a buzzer designed for a shaft speed monitor and to a 12-volt light inside the cab. It's also connected to the electric clutch that operates the combine header so that when the tank gets full, he can shut off the header without having to listen to the buzzer. "I've used it for two years with no problems," says Freeland. "Commercial grain tank monitors sell for $150 to $200. I spent less than $10 to make mine. My only expense was for the buzzer. I already had the push switch. The flap can be adjusted up or down on holes in the angle iron depending on the type and moisture content of the grain. For example, wet corn piles up at a different angle than dry soybeans. "The grain tank extension is too high to clear my shed door so I had to hinge the 2 by 4 so I can fold it down when I put the combine away in the shed for winter."
