I went for a walk through my local case ih dealer's used equipment yard today and found a 10 ft. mm disc, it was there on consignment, it's in nice shape, needs some work, the former owner welded flat iron strapping to the frame I think to hold some weights?? ( took the quick coupler ends off the hydraulic lines? why would he do that) tires in nice shape, will be going in on wed. or fri. to pick it up with the dually and the gooseneck.

Those were a good rugged disk back in their day. It will look like new with a little red paint. Made by Krause. We still have the 14ft our dad bought back in the late 50s and we were still using it up until the Vista era, then had to get something bigger. Never a weld or break on ours even though we pulled it way too fast with lots of power for it's size. My goal is to put new bearings in it and use it behind the GB propane just for fun again.

This disk was not made by Krause. It is a Krause design however. The disk was made in Hopkins. The very very first disks were made by Krause, and they had a different leveling screw on the hitch. There must have been some sort of licensing agreement between MM and Krause. I'm not sure about the early disks Krause made for MM, but there is a difference between the production Krause disks and the MM disks. On the Krause disks the rear main frame is ahead of the rear gangs and it limits the distance the gangs can be angled. On the MM disk the rear main frame is behind the rear gangs and the rear gangs can be angled way past working position to narrow it up and get it through a narrow shed door.

I have a question guys, that screw set up on the hitch besides setting the hitch height for hook up how do's that come into play when your in the field discing?? is it used to keep the gangs level, or put more or less pressure on the front or back set? my experience with discs has all been the 3 pt. type, using the top link for adjusting.

got the disc home today, and of course got some surprises, the reason the former owner left the ram and hydraulic hoses is both hoses rotten, ram leaking! found one 14" wheel and tire on left side and one 15" wheel and tire on the right side :? now the question is which one is the right one?? here some pics of unloading and hooked up to the m5! looks like it belongs there

I believe my MM disks have 14" tires on them.

thank you Leroy, I will have to get the screw unsiezed and working properly again, sprayed it down with fluid film last night, i'll give it a few more soaks and keep working the screw, the screw is just one of the issues, the grease nipples are all packed with hard muck I don't think this disc has seen a grease gun in years grease nipple missing on the main center wheel pivot and you can see shiny metal on the cross pipe shaft where it's been raising and lowering for years with no grease. why won't people maintain their equipment :? if a grease nipple is missing repace it!! if it won't take grease replace it!! if a piece gets broke, bent, or busted repair or replace it! a $5.00 tube of grease will save you thousands in repairs and hours of needless time spent and usually just when you need that equipment. i'll get off my soap box now and thanks again Leroy

It could have been ordered with either size wheels depending on what the farmer had laying around that he took off his car or truck as being too wore fore road use safley but still a solid carcas they he thought was to good to put in junk as sometime one of his farm machines would need them. People at that time would not spend the money for a new tire when a used one would do the job and then just set for 11 months out of the year. Only if it was an odd specialy designed tire would things come on new rubber. That one of each size says he had a tire go bad and he just picked up one he had laying around that would bolt up, not taking time to bet the flat repaired. I would look for a 15" as 15" tires are easier to find and get the largest that when you put it on will clear the frame, you will still be able to get all the cutting depth the disk can do with the larger size but you will be able to raise it higher for road travel. And the tires have to be exact same size or one side will cut deeper than the other making ridges. I only had wheel carried or full drag type with no carring wheels, never a 3 point hitch one.

thank you Leroy I will go with the 15" as I have some good used 15" tires here, and having a bit more clearance makes good sense. will take them into my local tire shop and see if they can source a rim that will bolt up.

Should be a standard implement rim of either 4 lug, 5 lug or 6 lug. I don't know how many lugs MM used. Loads of then in parts yards at way cheaper than new. Make sure you get matching rims in width as well.

Leroy I talked to larry at our local tire shop and he said no problem they are standard rims for implements and I will take both in the 14" and 15" and get him to match a rim up with my 15". both rims are 5 bolt and I'm going to keep the 14" as most sickle mowers take 14" rims. got the leveling screw working nice and smooth, one hand to raise or lower soaked it all night with fluid film and gave it a few bumps with my large rubber shot hammer and away it went. that fluid film is excellent stuff for penetrating rust and lubricating. the weather is supposed to warm up here in the next few days so will steam clean the disc and give it a good go over check for any problems, cut off those flat iron pieces welded they on for holding more weights and finish setting the scrapers on the other 3 gangs.

put another 7 or 8 hours on the disc today, cutting off all the flat iron strapping the former owner welded on to carry weights, cleaned up all the welds and primed. steam cleaned the disc and under all that muck it was in great shape no cracks or nasty surprises, removed the leaking hyd. ram and rotten hoses to go to the hydraulic shop for new hoses and rebuild the ram. pulled off more scraper brackets, heated straightened them in my press, reinstalled and set them close to the disc blades. replaced all the missing grease nipples and greased. looking at all the bent and twisted scrapers on this disc I'm thinking the former owner was pulling it with at least a 100 hp. tractor and pulling it way to fast. it is a testament to how well mm built these back in the day, to take that kind of abuse and still be in great shape.

evening all got a call from the hyd. shop this afternoon, and the ram for the disc was to far gone to rebuild, the pitting and scoring was to deep to make it worth doing, mike at the hyd. shop said it would be more money to fix than a new one! so we will have new ram and hoses $173.00 for both. not to bad, the wheels are at the tire shop to match up the 15" rims and put a pair od good used tires on so the disc will at least be running level!
