Spindle Assemblies are crucial parts for your lawn mower cutting deck that work together with the pulleys and belts to perform clean and even mowing,which enables the blades to work smoothly for an even cut. The blades of your mower rotate around the spindles, If your mower blades produce weird grinding noises, have a hard time spinning or spin unevenly then you may have a problem with your spindle assembly, if the spindles are bent or broken or if the bearings get worn down, your mower won’t operate as it should. Fortunately, you can replace the spindles or the spindle bearings yourself to fix your mower.
