I am on the market for a garden tractor. I have some short term needs for special attachments like a tiller and/or box grader and maybe and auger/post hole digger. Long term, this is going be for cutting grass. It seems that there are a number of sub-compact garden tractors with PTO attachments that might fit my needs (Deere x500, Cub Cadet 2500). I am no expert on tractors, so my question is are these sub-compact tractors using a 3 point hitch (class 0?), or some other proprietary design so it's harder to find OEM attachments? Are there any good recomendations as to new/used models I should look at that would meed my needs. Ideally, I want to pick up the tractor and tiller this season - what do you think is a reasonable budget to spend, with the expectation of picking up some of the other attachments next year for fence building, etc.?
