How to Remove & Sharpen a 5' Bush Hog Mower Blade

The Bush Hog SQ160 has a 5-foot cutting deck to tackle the toughest lawns and overgrown areas. As part of the Squealer family of cutters, the SQ160 and the other models in the series are made to be hooked up to the back of a tractor during operation. Bush Hog has made blade replacement easy on these models by installing a blade nut access hole on the upper side of the cutting deck. These access holes make removing the blade on Bush Hogs for sharpening simple.
