Need Help Selecting the Best Zero Turn Mower?

Our goal at Ferris Commercial Lawn Mowers is to help you and your landscaping company make the most of your time and money. The benefits of our patented suspension systems add up to increased productivity for you. Many operators are not aware that they slow down to compensate for uneven terrain — until they test-drive a Ferris with suspension. Isolated from these effects, the operator naturally maintains speed, taking full advantage of available horsepower.

The result: More acres per hour and more money in your pocket. Try out our mowing productivity calculator below or reference our handy mowing productivity chart to determine just how productive you can be in a few hours or in a full days work!
