Well I brought the 350c home and I am very pleased except that moving the ripper to the 450 would mean that, as Jason pointed out, I would need a different back hoe bracket for the 450b and I do not have one at this time.
I do have 3 brackets to fit 350s. Trade anyone?
It would also mean some mounting changes with the rops on the 450b as well
I could not find a model number on this ripper. It has been modified to fit the back blade 3 pt hitch and it is interesting. I have not tried this blade yet but the crawler works very nice.
This crawler had a career loading peat and the two bucket extentions fit on the outsides of the bucket. It might be good for snow!

First thing we do when buying anything. get Fraser to check it for mice. He is the best!
So I guess I got a little closer to my goal, I have a ripper but no way to attach it to my 450. Suggestions welcome.
