I have only run my box blade on the road. If I was looking at going into the bush I think you might want to go with a 5 foot. Of course it all depends on how many roots/rocks etc you will snag, could get hard on the machine. As I have a Woods backhoe I would use it first to get any big rocks and roots out. I use my tractor but trying to be carefully not to abuse it. You are the best judge on what is on/in the ground. I have made a rough road in some of my heavily wooded area for my wife to walk with her goats but used the backhoe and front bucket for that. Don稚 have many rocks on our place but lots of trees and brush on the ground, find the backhoe it great for moving it to make a path.
