unless i lower it to a very low setting it sits unlevel. with the right(sitting on tractor) setting higher than the left. i also dont exactly understand how much contact the caster wheels should contact the ground. should the deck ride on the gage wheels and casters? or should they only occasionally touch to prevent scalping? my casters seem to bounce around violently on anything other than the smoothest ground. i am afraid i am wearing out the casters and gage wheels. simply put, i am unsure exactly how this deck is designed to work. sorry for so many questions but i am lost.
