I'm in the boat of the constantly fixing mode on my 742B. If I would of known what I was buying (first time buyer) I may of made another choice but, I got a little excited and bought it for around 8500 . The machine ran great the first year, and was bought with 3 attachments. Two buckets, one grapple, and I bought a custom made brush cutter for it. Anyways I am in the process of rebuilding my Mitsubishi 4G32 engine thats a 36 hp engine. It has worked for moving dirt and a lot of dirt can be moved without much problem. Digging in to the ground with it is a little iffy, but once you can get it to dig in a little bit it works pretty dang good. I have cleared land with it. I have leveled trees (soft variety ex. pines and smaller trees without any problem. I have leveled driveways and moved some pretty big boulders without much of a problem. I knew the kind of work I was doing wasn't real hard on the machine but I was pushing it at times (who of us doesn't) Lol. There are benefits and few if any, but the 742B weighs approximately 4,800 pounds, which makes it easier to haul around without mega trailers. I wouldn't want to load it up and haul it real far maybe a 100 miles max, unless somebody wants to hand me their bank account to let me drain it. Thats a joke people, relax. Anyways it's a FUN machine and it does what I need it too. It's like everything else, when ya buy something later you think hmmm... maybe I should of bought a bigger one. Hmmmm too late. I am rebuilding the Mitsubishi motor as of right now. I have had a hell of a time finding parts as it's getting obsolete. But after pulling out the few hairs I have left I have found parts and have been learning with the help of a friend how to rebuild a motor. I have spent around 2800 bucks on it. I think I have everything I need for it and just today I brought the head up to be cooked, cleaned and leveled. That is about 400 bucks. But when I'm done it will be a new machine to me. You noticed I didn't say anything about the hydraulics as of yet. So far so good. I don't want to jinx myself. I'm into it now and for the near future and I'm gonna have to love it or leave it for good if the hydraulics faulter. Just my 2 cents.
