My Grandparents own a 153 acre farm that we have leased out for soybean. We have an older ford gas tractor now that is getting pretty weak. What we use the tractor for is mowing around the soybean fields, plowing and disking large gardens and general work around the farm. No large field use or haying. Would a tt50a be a good replacement for our old ford? The only thing pto wise that would be used is a 5' tiller and a 5' bush hog.
