For those that responded and got no reply......yes, much easier than bucking bales off the ground and up into the barn loft. Crew of 3....driver and 2 stackers can do 1,500 to 2,000 bales per day if they get after it.
BTW, transmission only says 540.....no D. Best guess is the builder of these contraptions bought 318 industrial engines, an NP540 transmission and a low speed rear end from Chrysler.......seems to be highly similar to the drive train components on at least one variation of a Dodge D600 medium duty truck.
