RE: plows or tillers for an ATV?
You guy' s might want to look in the yellow pages for equipment rental. We have one here and can rent garden discs $45/day, spray rigs 30/day, spring tooth plows(which are better for breaking new plots, acts like a lite sub-soiler), 40/day and garden culti-packer 35/day. I am fortunate to have a 35hp Mahindra tractor and pick-up disc but I drag plant and pack with the rented atv equip. They also have a motorized field and brush mower that will cut down 2" stuff.
