BOB, The 3510 gear transmission tractor and the 4110 tractor use the same chassis & loader, so the lifting capacity is the same. The 4110 uses a wider front tire which improves your floatation with the heavy loader loads. I have customers who use 4110 tractors to lift 600 to 700# bales, on a steady basis. I even have a customer who uses a 2615 tractor to lift the bales into the feeder. Of coarse it wouldn't lift it to full height but it will get it up 3' to get it into the feeder. The 3510 would do fine with the light to medium weight bales. Definately load the rear tires.
