Brush mowers are sometimes called brush cutters or bush hogs. They are used for clearing land that has mixed growth, including small saplings. Their purpose is to cut, and while the cut is clean, they are not intended for a uniform lawn look. Brush mowers differ from finishing mowers in that they have a central wheel on the rear of the deck. Their purpose is functional, and they should be the choice if you are maintaining pasture or meadowland or keeping large embankments or ditches clear of weedy growth.
Finishing mowers are designed for neat, tidy lawn mowing. They are designed to cut grass, though some brands are also able to handle heavier jobs. These mowers are wide and close to the ground, with anywhere from two to four wheels. They deliver a smooth, even cut and a finished appearance to your lawn property.
One of the differences between brush and finishing mowers is their height adjustment. Finishing mowers are usually adjustable between 1 and 4 inches, similar to both push and riding mowers. Brush cutters are adjustable up to 10 inches. This adjustment allows for rough terrain when cutting uncultivated land.
Brush cutters are typically built tougher to deal with the tougher job they have to do. The deck is taller than a finishing mower and not as aerodynamically designed. Instead of attaching using a shear pin like a finishing mower, the brush mower may use something stronger like a slip clutch. The slip clutch minimizes costly damage if the gear box is hit on an immovable object while at work. While brush mowers can be used to cut grass, the opposite is not usually advisable, as the lower deck and blade settings of the finishing mower can be damaged by heavy brush.
