Min tractor to lift a round bail off big rig

I've go two factors, need the smallest tractor I can find to get around in a horse farm (in and out of paddocks and stalls).

Secondly I may start taking delivery of round bales via 18 wheeler, so I'll need to unload it. We have both height and power issues.

I go back and forth on getting what I need now vs getting what I think I'll need latter.


What is the min size with enough height and power?


Blah blah blah
