This week on the Super Smart Farm Show, we're heading out to the barn to learn all about how tractors power the tools they pull behind them, from balers to tillers.

Tractors pull a variety of tools behind them, but tractors engines, the source of these tools' power, are all the way up front. So how does the power from the engine travel all the way back to those tools? The answer lies in a tractor part called the power take-off. But what is a power take-off and how does it work?

Join host Elmer and Frank the farmer as they figure out the answers and learn how power take-off keeps those mowers mowing and tillers tilling.
