The turbo saw is awesome. I am a mulcher and I almost bought one for a job that would not allow my mulcher to be used. If you are clearing invasive species like mesquite don't forget that you will also have to chemically treat the stump or grub it out or it will regrow quickly and be thicker than before. If you want to use your tractor I would use the turbo saw to get a smooth
cut and then use a 50-50 mix of roundup and deisel to kill the roots. Or better yet hire me and I will have it all mulched up in a few days!
