Update: County Line single bottom plow worked very well, cut through the sod and clay easily, though the tractor had nowhere enough traction for this. Sure now understand the benefits of MFWD. I spent half my time with the diff lock pushed down, and I wondered if constant use of that, not slipping it, but fully engaged, heats up anything. Boy did it work. Had to do much of the deep plowing going downhill since uphill was just too hard on me and the tractor due to lack of grip. Even with my big ag tires, I've only got 2000 pounds to work with.
Nice plow, a friend picked it up for me because he was closer to TSC, and they took fifty bucks off because it had been sitting out awhile, and had some rust spots on it. Ok, that's fair. Built very strong, my 25hp tractor isn't going to stress it, but I noticed the whole apparatus was cockeyed when I put the tractor away. The links weren't that out of wack before, maybe something moved. Very pleased with the plow's performance even when I'm sure I didn't have it adjusted very well. Did the job, turned everything over and I'm ready for the rototiller. I suppose I could disc it, but because the soil is still moist and sure clayey, I think the less I drive on it with the tractor the better, and will use the much lighter garden tractor from now on.
p.s the head on shot of my 255 shows some messed up steering angles...headed to the repair shop for some new knuckles, I could see something moving that sure shouldn't have been, plus the one tire turned in significantly more than the other. Likely PO ran into something and bent the steering rod, but maybe enough adjustment in there to help plus a few parts. The turf tires are worse than useless in wet clay, geez slid all over the place once they became solid mudballs, and the lack of weight on the front made steering almost impossible at times. Kept veering off to the right, and being a boater, I know my rudder was pushing me that way... I have a 300 pound custom weight box I built for my Gravely; don't know if 300-400 pounds would help over the front tires, but since it steers so easily, I'm going to find out. I had to use the diff lock, i had to use the brakes for steering, I was pumping away on whatever worked. And boy am I sore now. Good sore.
