A boxblade is just about useless if the tractor doesn't have a load/depth sensitive three-point. My old German-built Deere (which wouldn't run more than about 45 minutes without overheating) had a fairly sophisticated control on the three-point and you could set the three-point to a depth and forget it. Perfect for surfacing the roads out here.

But, I got tired of shredding my place 6 ac at a time (because of the old Deere's terminal overheating problems) and bought a 50hp Kubota. The thing runs for hours without complaint but I've destroyed more road surface with it's crude three point control than I'm willing to admit.

Nowadays, I use other blunt instruments to do road work and the tractor pulls the 10' shredder and hauls hay.
