The main indication of a lawn mower blade not turning is when you've made a few passes on the riding mower, but you can't smell any fresh cut grass. Something is clearly wrong. The best feature of zero turn mowers is that you can disengage the blades going over curbs and other things you don't want to cut. But when your riding mower blades won't spin, you might as well be driving a forklift or a dune buggy. So, what's the answer for fixing mower blades that won't engage? Repair Clinic is here to help you regain your neighborhood title as Lord of Lawn Care. We'll help you diagnose the problem, sell you the right parts for your model, and show you how to install them. Then, you'll henceforth be known as the DIY Lord of Lawn Care.
