On a farm or other agricultural land, a rotary cutter for a tractor is a common piece of farming equipment used to chop brush, weeds, and grass. A rotary cutter, sometimes referred to as a bush hog or brush hog, is a tool that is mounted on the rear of a tractor and is used to cut vegetation using one or more rotating blades.
A self-healing mat specifically made for the purpose is used by patchworkers to cut cloth using a particular quilting ruler and a rotary cutter, which is a tool with an extremely sharp circular blade. They are typically employed for cutting fabric with straight edges.
