Welcome Dromedary! I too came to tractors late in life!
. I'm mostly a lawn tractor and vintage garden tractor kinda guy, but one of the quick bits of advice I can give you from what I've learned on this site is that you're PROBABLY looking at a small compact utility tractor (aka a SCUT). This is because there aren't many back-hoes made for tractors as small as garden tractors... It usually goes in this order from smaller/ cheaper to larger/more expensive: lawn tractor; garden tractor; SCUT; Compact Utility Tractor;Farm Tractor. Front end loaders are FAIRLY common for garden tractors, but are not as capable as those made for the bigger machines.
HTH, and good luck!
