No such a thing as dumb question if one will to learn or listen.
I had Kubota B7100 w/turfs tires,and turf tires work very well..did't cut the lawn and good tractions if ground dry,if not tire chains made BIG different.
On My Kubota L all four tires R4's loaded..good tracking doesn't hurt lawn if wide swing,but not as good as R1's...Some tractor models if you decide to put on tire chains on rear you'll need spacers for each side..$$$"s
Bucket hooks,I like hook on each side and one in the middle..if you decide to pull some heavy on end bucket hook,becarefull not to over pull or raise rear tires of the ground,you could very easy put seal in the front..$$$'s
Backhoe..kind depends what your planing to dig or type of digging,if I I would purchase sub frame instead 3pt hitch setup..better chance of spring/bending/breaking hoe etc.
Wishing you the very best,and do share some pics when you can.
