Barry, Picking up those heavy rocks really demonstrates the lifting power of the Zetor tractor!
A picture of an IH 140 plow is attached. The front end loader on my Zetor 4341 picked it up off the trailer with no problem, however, when I put a front wheel into a dip in the ground, I found myself wishing that I had already filled the rear tires. It got a little light on one rear tire. I got the plow to the ground safely. The three point picked up the plow with no problem and the front wheels were still on the ground. The garden site I wanted to plow was tight to get into so I decided to take off the fourth set of bottoms. With the three bottoms, the plow worked quite well. The photo is not my actual plow. The one in the photo is in better shape. But that dealer wants $2000 and I only paid $125. I can put on a few new plow shares and a coat of paint for the difference.
