I have a cat d5h with a straight tilt blade "no u-blade" and really wish it had the semi-u blade but I guess I would have to upgrade to a d6. I've always been a cat person but really like the Deere dozers. I'm kind of wanting to upgrade to something a little newer with a cab and wanting to stay in the 30-35k pound range. Ive looked at the Deere dozers a lot on the Internet. Is a 750 the smallest that is available with the semi-u? I really like the looks of the 700j but haven't seen one with a straight blade.
