I'm a newbie looking for advice about my impending purchase of some sort of mechanical device to mow grass, mow 6-foot nettles and 2" ailanthus trees, push or blow snow, conquer 30% grades without killing or maiming me, clear of light snow and dirt from a concrete driveway, till a garden, split logs, chip branches. Thinking Steiner or Ventrac. Not sure how much HP I need. partial to gasoline engine, maybe with propane possible. Budget is whatever it takes but not more than that! I'm all in for saving money on used stuff (aren't we all?). I've got about 6 acres, but will only tame about 3-4 more of it this year.
