I did a search but couldn't find much info on this. We've got a old Cockshutt disc set, pretty large with spring loaded wings.

Anyways, 2 bearing are finished, and you guess it - having trouble getting nut off.

From what I could find on here, best bet is to soak it daily with WD40 for a week then try. But, how do I keep the whole disc set from spinning when trying to remove the nut? The discs are totally round not corrugated so it spins quite easily even with full weight down on groud.

Tried a pipe wrench on opposite end, that was .... funny.

put some down pressure on the gang while its sitting on a board with a front end loader. it should hold it. we have drove a 4 x 4 between the frame and a blade to wedge it in place.

A 3/4" air gun is my first step. I then set the gang on a 2x6 or something to wedge it if it turns.... If the gun won't move it then I go to a 3/4 drive with 6+ feet of pipe. If that doesn't work I heat it and then drive it off with the gun, hot. Make sure the threads are clean first.
Failing that I'd cut the nut off with the torch. I haven't had to do that yet....

Water Displacer #40 is about as effective as spit. Get some Kroil or PB Blaster and add some heat and vibration.

We pften set the portion of the disks that we need to loosen the nut on ontop of a 2"plank,right down with the wheels all the way up.Than we heat the nut good and red with the tortches.Let it cool,or cool it with water to prevent the threads from stripping.Than we use a pipe wrench on the nut with a pipe on the handle.It has always worked for us.Just how we have done it,any way that works for you is best!

thurlow summed it up real well. Before we had an impact wrench, I would use the largest pipe wrench that I had with a pipe handle extension if needed, and clamp an old "well" wrench, I think they are called to one of the spacers. I suppose that you could heat the nut if nothing else works.

Make a disc clamp for holding plough discs while undoing the retaining nut. It consists of a
steel plate (1/2" thick, Around 6"Square) a slot
is cut into this (aprox2.5"long)that will fit the
outside of the disc. A nut (5/8") is welded close to the slot. The plate is then locked to the disc
by screwing a bolt through the nut and tightening it against the disc, let the plate lock against the frame, ground or whatever.

Simplest is to use an one inch (3/4 would probably work) impact wrench, but if you don't have one..... ...never saw a disc gang that you couldn't wedge a piece of wood across several blades and get it to hold; might take a 2x4, 2x8, 3x6..... ...whatever will jam in there. If the spacers/bushings fit the axle...some do, most don't..... .you can hold one of them with a pipe wrench.
