SWMPBGY1, I have a Walco 60" rotary cutter...

I've used it to clean up about 3 acres of overgrown brush and small saplings. It worked very well and maintaining in the future will be much easier. The 3030 seems to run it very well and didn't seem to struggle much with it at all. Mind you, I was really taking my time cutting as I didn't know what I was going to encounter. I keep my bucket about 4 inches off the ground and just crept along. This way, it knocked down a lot of the brush before it hit it with the mower, and secondly it let me feel if there were any rocks that I shouldn't be trying to mow
Thanks to all for the positive comments on our home.... we really enjoy living on the waterfront. The tractor has been amazing for helping to maintain this. I should have pulled the trigger on this deal long ago.
