I think the plow is a jd 55 or something close to that with the small beam, 3-14 with mechanical lift. I have been looking for a 4-14 plow either hyd or mechanical, but haven't come up with one yet. I was so happy with the job the plow did that I think I would get another. Was plowing about 8 to 9 inches deep in 3rd gear wide open, was a little fast for me but it looked like a nicer plow job. I got the 555 diesel from an old farmer that said it hadn't been worked in 20+ years, so I wanted to give it a good work out. I think a 4-14 in second gear would be an ideal setup. Was the most fun I have had in awhile.
