i am looking for a small tractor. i need something small enough to get into a fenced in yard, but large enough to mow 2 acres. i want it to be fairly quick and mow cleanly in thick grass (THICK ST AUGUSTINE). i'd like to use a box blade with it to do small leveling jobs and a set of blades for a garden. it would have to be heavy enough to drag small trees (12 inch diameter trunk) from the woods behind the house but light enough to not damage my field lines or compress my lawn. upgradability to a front end loader would be a plus! any suggestions?
