Quick Update:
Good call on getting the box blade.
I ended up getting the 4ft. Northern Tool Box blade since it's free shipping with store pickup.
The box blade is very well built and heavy and I'm impressed with it. Will have to see how it holds up over time.
I used it all day yesterday for the first time and really put it to work. I did slightly bend one of the scarifiers sideways a little bit though, since I caught a stump I forgot about and didn't stop in time so the front end started coming up. Otherwise still looks almost new after hitting tons or rocks, roots, ect...
Tractor has plenty of power for a 4ft. box blade. Problem was traction occasionally, which adding liquid in tires would help, but I haul the tractor to 3 hunting tracts so don't want more weight.
All in all pleased, but still have a lot of work to do on the road. Wished I had bought the 4wd tractor though, since a front end loader / box blade combo would of helped.
