snowplow, loader, 3 pt for 41 farmall a

I guarentee you, do as I suggested and you will be money in over the next 5 years. You can't begin to imagine the items your going to break if you mount hydraulics, loader and 3 point hitch on that Farmall A

There are two choices:
1. PTO-powered hydraulic pump and external reservoir, either built from new components, or in the form of an old Char-Lynn PTO unit(rare). The problem with this is that every time you push the clutch, you lose hydraulics because the PTO stops. The rear-mounted pump and reservoir will also interfere with a 3pt hitch setup.
2. Cobble an old power steering pump on to be driven off the engine via a belt. The problem with this is the pump will be low-volume so the loader and 3pt will be slooooo ooooo ow. The pump will stick out and interfere with the loader. Plus, it will almost certainly be problematic and unsightly unless you're a darned good fabricator.

In short, it can be done, but it just ain't practical.

Try the classified section here (post your own want ad too), ebay, etc.

Not going to be easy to find the loader, and three point hitch will require additional modifications to be feasible for an A.

Might be more $ and frustration than you want to get involved in.
Might be better to look for an IH 300/350 utility with all of the above, and keep the A for whatever you might fancy.

3pt can be fabricated or store bought through Worksaver or Hugh MacKay can help you in that department but you will need hydraulics

Front loader IH manufacture IH 1000 loader but once again you will need hydraulics

IMHO I wouldnt even put a loader on that tractor, the front spindles cant take any real weight !
