I've been wanting a disc real badly to go with my two bottom plow for next spring.....
everything i've looked at is well worn, high priced (some not too bad) and the hard type to adjust.....
yesterday, i stopped past an ole' boys place to see what he had......one set for 250 and they weren't too bad......someone did a crappy job welding the 3pt hitch up on but like grandpa says, "poor people have poor ways"

his other set he wanted 500 for and they were a better looking set but the adjustment was still a pain......i wanted something quick........so as i went up the road i thought, "well, i'll just post a thread on TBN for people to show what type of disc they have......." i wanted to see what was available in easy adjustment......
after i drove up the road and stopped by a kubota dealer (no good deals, right??) i noticed a pretty nice looking set of discs on the back of a ford 600 or so.....whoah, it had adjusting handles but i'm sure they didn't work right.....boy was i wrong......the adjustment was VERY easy..... from the lot i called them on my cell phone (the two kids were asleep in the car and i didn't want to leave them).......come to find out, this well built disc was a MF 6'.......they were asking 650 which i didn't think was too bad, being that most hard adjustment ones were just barely less and these looked to be in excellent shape......so, i went home drooling over this particular set of discs....
i started to post a thread on here, but a quick search and ole' farmwithjunk has come through again......now i'm on the look out for a 7 1/2 foot set...i would assume you'd want your discs just a bit wider than your tractor, so you don't get too close to the actual plants...
thanks farmwithjunk, again, and thanks TBN
Here's a disc that didn't break the budget. The basic design stayed with the Massey Ferguson line for nearly 30 years. Not only does it do a fantastic job, they seem to be extremely durable too. It's a model #25 MF. The 2 levers change front or rear gang angle on the move. Each gang has a single bolt that can be removed to allow that gang to float independent of the others when on rough ground. They were built in large numbers. Still quite a few left to be found on dealers lots. I paid $400 for this one. That's about average for a #25 disc. This one is the largest of the 3 sizes available. (6', 7-1/2', and 9') They can be cut down if you find a deal on a 9'er. Remove 1 or 2 disc blades and spools per gang, cut down and re-thread the ends of the axles, and you have a smaller model. Most I've seen are 6' or 7-1/2'.
Not only do these sell cheaper than any new disc I know of, they do a much better job. Massey sales literature from the day, nor the manual list's weight, but I'd estimate this 9'er weighs close to 1200lbs.
