I have a lot of areas with irregular ground, containing small dips & humps. I need to keep some of them mowed as well as possible. I've been using a rotary brush cutter on my compact tractor to do a reasonable job, but it's hard to keep it from occasionally digging into the ground. I'm afraid that a finish mower would not be able to take the abuse it would inevitably get on this rough ground. Is there a rotary cutter that has wheels in the front or some way to keep it from digging into the ground (like a typical finish mower, but more heavy duty)?
