I've got a Woods GB65...Great BB, built like a tank, and works great.
I dunno...My issue with BB's is this.. Reading a multitude of posts, I used to think it would be great.... I needed some ballast anyways so I bought the BB just as much for Ballast as a tool, it does work great dont get me wrong..but I havent used it for either in 1.5 years. My BB is actually 150 miles away at my bro's place and thats what really got me to thinking I dont need one. Just seems to me a BB is a Jack of all trades, master of none. I've had the power rake on the back of my tractor all summer...now THATS a useful tool.
I got a KingKutter XB boxblade. Never had a problem with it. Very nice unit. I have even tried it on the 3720 just to see what it would do and it handels it great. I maianly use it for dirt work and grading roads and gravel lots. I have taken off the scarfier teeth for grading and it still does a great job. I did have a can of JD green paint a while back and almost painted it green but i am using it on a red tractor so XB orange works fine for me.
I have a Frontier BB1284 1250 lbs with hydraulic scarifiers. Made by Woods Gannon this is the heaviest model I have seen so far. This thing holds about 1.25 yards of material, and has hinged rear blade. Works great with topntilt hitch.
For most jobs in my area I will use this after the 110 has removed the stumps and larger rock on the surface with the rock bucket and hoe. This boxblade works well to cut down the larger mounds and shape the properties. After running the boxblade I normally run my landplane grader to finish it off.
