This not a commercial blade by any means but I was pleasently shocked how tough it really is! I have no idea how radical you need to get but I have hooked this into rocks that would bring the whole tractor right around sideways and the blade is still as straight as a gun barrel. If you need to get down into really hard ground of course a heavyer one would be even better.
For the money these will surprise you, I got mine cause a neighbor bought it and then had his tractor "picked up by the bank"...........
