Too bad Markham is out of business. I wonder if North American Implements in Denton NC is the same bunch? Same city. Products look the same. I would look at their light duty grapple or their NAI grapple and see if they would custom make one of that design but using 1/2 steel and spacers between the tines and 48" wide with one thumb. In my opinion, that's the perfect design for 35 to 80 horse tractor. Markham made mine in only several days or under a grand if my memory is correct. I operate mine with a WRLong electric over hydraulic valve. Works great. Have really abused mine but only show a few minor bends in the pacers between the tines.
