Both of our foam markers shelled out within 3 or 4 months. In each case, the motor failed. Same manufacturer. The first unit was installed by the maufacturer, and it lasted for about 3 months with very limited use. I won't mention the manufacturer, but these units sold for about $250. Anybody recommend a good foam marker for ride-on sprayer/spreaders that doesn't cost an arm and a leg? One that lasts longer than 30 hours?
