Welcome Mamatried. There is a distribution block on the right side of the machine near your right foot, at least on the HST machines, where the loader plumbing connects. With you having a 2wd you must be very careful when lifting heavy loads, because as soon as your rear wheel leaves the ground you have lost your brakes/drive and things can happen quickly. You will want to ensure your rear tires are loaded with ballast and/or having a counterweight on your 3 point while operating your loader.
As far as loader options, Woods is by far the most commonly used brand. There are other options out there, but for parts, availability, etc you're best off with Woods. Be prepared to pay out $4000+ for a new loader. Often you're better off selling and upgrading your machine to one that has a loader than to try to retrofit one to what you have unless you got yours REAL cheap and its in excellent condition.
Good luck and keep us posted!
