Thanks!
1*The R4 tires are good in the muck, until the treads load up with mudd, then forget about it. I had to use the loader to push me out. The less weight you have on it, the less chance you will get stuck. I went over that same spot without the ballast box and it went through fine.
2*The 48" at TSC I believe is a KingKutter. Maybe I could bargain with them for one thats been sitting in the rain for the last year. What is the general consensus for "safe" max width for a bush hog?
The RFM I think might get pretty beat up in our back field. Its not all smooth, with many ruts. I also like the ability to run over small trees and sticks, etc.
The BXpanded forks are great! They really are top quality, fit and finish wise. My only gripe is that they put the weight so far forward, you are limited to a lesser weight than the loader can actually handle.
3*you NEED a ballast, even for the most minute load. Trust me!

I love my BX.
