Hi, Plowed for a couple of rounds with the M pulling 3-16's. In some spots that were drier it pulled great but as it got wetter in spots I just spun to a stop which is not so good with a clutch lift plow. I didn't get in enough rounds to put a high polish on the bottoms, just to wet to get traction with no weight on the tractor. They had very little rust on them since I plowed with it last year just not enough to get a good polish then either. I gave up with the #8 and M and went home and got the Oliver with the 565 4-16 semi-mount. Plowed about 15 acres with it though muck and sometimes mud. Altogether I got about 9 hours of plowing in. It was a great day! Half mile pulls. 85 acres. Two tractors. Clover as green manure. I just wish I had more weight on the M. How much is needed as a rule for 3-16's and/or 4-14's? I also have a #8(?) hydraulic lift with 4-14's. Will the M pull that with enough weight? With you not knowing the soil types around here could you make a good guess? Thanks! ...Randy
