Strips of uncut grass often come from ground speed too fast, a dull blade, or cutting wet, springy grass. The operation section explains how to get the best cut for your area and conditions.
Manual Section: OperationDrive belt slipping
A slipping belt loses blade speed and cutting power under load. The maintenance section covers belt replacement and setting the tension so the belt drives properly.
