My zero turn mower sucks down almost a gallon of gas with every mowing, and that happens every week. It always gets fresh gas every 3 weeks, when the 2 1/2 gal can is dry.

The Craftsman 42" cut tractor before the zero turn lasted 14 years with never an issue (after I fixed the anti backfire thing in the float bowl). I ended up replacing it because the brakes were shot and the deck was showing signs of issues. My grandson turned it into a yard runner. Gene
