Any GradeMaster owners here?

Oh, and I know you are wondering...so here it is:

It looks like you were pushing too hard in reverse, a lesson I learned the hard way, too: http://www.tractorbynet.com/forums/owning-operating/204404-ok-push-trees-over-box.html

MtnView,
No, I have draft control, but no float. My top cylinder does not leak down, and I am pretty sure the side one is pooched from the bent shaft. I am just hesitant to replace it, then have the same problem since they ain't cheap. So if I want to guarantee against leak down what do you recommend?

DPOCV is the only guarantee. I'm not sure about what size CCM would use for you, but I know that one of my cylinders is quite a bit stronger than the one that you bent. If your valve is good, leak down should not be a concern. My side links give you equal tilt to each side. Sounds like you are probably looking to get a unit from CCM though.

Good luck with making your decision.

Actually, no, I can replicate the issue without pushing hard at all. It has more to do the the box being angled down in the front and the terrain(like backing into a ditch to clean it out). Also, my hyd top link is not ridgid, but will compress when force is pushed into it. This is good when brush hogging, but not good in other situations.
After I fixed everything, I welded two 2"x4"x1/4" sections of angle iron on the BB arms in an effort to prevent it from flipping again. Both of those tabs are now bent down almost flat, so my next "stops" will be made out of boxed steel.

Ouch, I just read your thread. I really try and take it easy when backing/smoothing with a BB. I always have this fear of breaking the case especially when the BB catches a rock, and I have lots of rocks.
