20 to 30 HP tractor.
FEL (front end loader) would be good counter balance weight, for heavy 3pt equipment. would say "heavy duty bucket" for FEL. you can get a thinner metal wider bucket, that is not really meant for digging or pushing snow. and really only meant for moving mulch. but only time i actually see these buckets are on business were loading mulch into customer trucks or onto trailers. vs moving mulch around.
you may want to get out of the "riding lawn mowers / garden riding lawn mowers" and go with a model that more of a tractor frame. were the belly of the tractor is a few more inches higher off the ground. it may not be much. but if you are plowing and discing, those extra few inches will keep tractor from bottom out in the dirt.
the bigger framed tractors that set higher off the ground in the SCUT and CUT (sub compact utilty tractors, and compact utilty tractors) will more likely also have more "weight" to them. that will help you pull plow and disc better. you might want to see about have rear tires filled with a liquid for a little more weight in the rear end. for better pulling.
i would say go for 2 rear hydrualic rear ports. for various 3pt hitch equipment. 1 most likely do this or that. but that second one, you may get a bigger discount on when buying. vs adding it on latter.
having upper front and rear working lights. that are high on the machine helps a good amount. from dealing with snow in winter, to being able to work the tractor a couple more hours rest of the year. to just being able to work right till sun goes down, and then spend that last half hour putting things away. those lights really do help.
you might want to look into the extras for 3pt hitch, various extra chains / sway bars. so you do not tear up the 3pt hitch. plowing, discing, bush hogging.
been to long i do not remember correct terms, but you might want to look into "draft control", "float", and weight transfering 3pt hitch adjusters. most of it is in the valves / levers. but some of it requires a sensor or like on the 3pt hitch. and hopefully built for the tractor. it makes life easier. vs consonantly bashing the 3pt hitch lever to raise and lower.
you might be able to rent a tractor, or 3pt implements. by asking local tractor dealers. or simply going down the road and asking some farmers.
