Rotary Cutter Guide | Woods Brushbull, Brushfighter & More

As a farmer or land manager, you know the struggle of dealing with unruly vegetation. Your current equipment might be leaving you with uneven cuts, frequent breakdowns, or simply can’t handle the volume of work needed.

How to Choose the Best Woods Rotary Cutter for Your Property

Due to the significant costs and weight differences between these cutters, it can be difficult to decide which is the right rotary cutter for your property. It’s important to be honest about the type of mowing you will be doing, and there’s a big difference between maintaining pastures and clearing brush. Keep in mind that rougher terrain, larger material, and hidden obstacles like stumps can easily damage cutters that aren’t designed for that level of use.
