It can be done, but it's pretty out there. Sounds to me like you need a GT with a FEL. Honestly, by shopping around and waiting you could probably pick one up better built and less expensive than you could build one.
Don't have every weekend free, but I do have lots of spare time. I work from home, so finding time to work on this project shouldn't be too hard. Even if it does end up sitting unfinished for a long time, I'm not too worried, since a lot of the fun is in building it, anyway.I gotta ask a few questions..
Do you have every weekend for the next 8 months or more to dedicate to this? Why i ask is with out that time it will be sitting there waiting for you for a long time.
Do you have a shop full of tools and a few that you havent used yet?
Are you a great welder?
Are you good with hydro set up?
I agree, in general I've found the mowing deck will get in the way when using the loader and the loader gets in the way when mowing. Lawn tractors are easy to get to mow with. Haveing two machines will eliminate your desire to have the hydraulic height adjustment, The best set up would be an articulating loader or mini skid steer, and a zero turn mower. The way used equipment is showing up lately I don't think it would be worth while to build a loader. I've seen Case 646 loaders selling for $2500 dollars lately, 2 years ago this was a $6000 machine. Everybody is hurtin and trying to dump their older machines. Just my 2cents, good luck, Edi think an articulated machine would be the easiest to build with 4wd. just buy a separate machine for mowing. craftsman lawn tractors often go for next to nothing
Is THIS the one you're talking about?The best one I've seen here on MTF and just about any other place,is the articulated Case one someone built..a 4wd articulated loader is hard to beat..but I dont know if it can be used to mow with a deck,but you could always use a pull behind unit..but I agree with the fact buying a used Case loader IS going to save a LOT of work,and potential for failure,or money wasted..it looks easy to build one,but DOING it isn't,and sometimes you dont realize that until your in over your head..
