About Rotary Mowers

Sometimes referred to as “rotary cutters,” rotary mowers are used to cut through tough material, including thick grass, weeds, brush, and more. They are similar to lawn mowers in that they feature one or more metal blades that spin to cut or chop, but instead of being walk-behind, most rotary mowers are PTO (power take-off)-driven and attached to a tractor with a three-point hitch or drawbar in the rear.

Rotary mowers are also distinct in that their blades are typically thicker than those found on a standard lawnmower, allowing them to handle more difficult work. While not necessarily ideal for achieving a clean, consistent cut because they are designed to chop or even tear away material, rotary mowers are ideal for work on farms, acreages, or ranches where various types of thick brush need to be cleared quickly and effectively.

Common Rotary Mower Features

Rotary mowers all perform the same basic function, but come in a wide variety of cutting widths, cutting capacities, horsepower requirements, and more. There are also single- and multi-spindle configurations, typically with one or two wheels. Single-spindle units usually have shorter cutting widths than multi-spindle alternatives, but that isn’t always the case. And most rotary cutters come with a range of safety features that may include cutting deck shields to protect the operator.

Cutting Width

While most rotary mowers measure somewhere between 4 and 20 feet (1.2 and 6.1 meters) wide, Canadian manufacturer Schulte sells an FX-742 rotary cutter with a top cutting width of 42 ft (12.8 m). Wider models allow operators to cut more material per pass, making them ideal for relatively consistent applications, such as clearing grass and brush in a pasture.

Cutting Capacity (Diameter)

A mower’s cutting capacity is equal to the diameter of material it can cut, a figure that typically ranges from 1 to 6 inches (2.5 to 15.2 centimeters). A rotary mower with a lower cutting capacity would be well-suited to cutting grass and weeds, while one that supports higher diameters could cut through thick brush and potentially even young trees.

Horsepower Requirement

It’s important to consider a rotary mower’s horsepower requirement prior to purchase. This can range anywhere from 15 to 200 horsepower (11 to 149 kilowatts) or more, depending on the size of the unit. Your tractor must have enough PTO power to run the machine, and its hitch must have a sufficient weight rating to support it.
