nut may have a lock on it to keep it from listening up. Otherwise pretty simple if you can get nut off without rest turning. May also depend upon how big a wrench you have

Getting the gang nut off is usually the easy part. :roll:

yep pretty much as simple as it looks.

I recommend you keep your old blades in case you need to cut the center out of them to make you some custom washers.

Often the axles stretch, the spools can wear a bit in length if run loose, sometimes there are just bad threads on the axle in spots, or new blades not being as thick as the old blades. Any of these issues can often be remedied with some washers cut from old disc blades so everything tightens up.

I think you'll find it easier to remove disks & shaft from machine if the disks that require replacement are very far inside the nut end of shaft.

BTDT! Soak axle nut with wd-40 for a couple days, drop disc in the ground, loosin up with big socket and cheater pipe.If the blades want to still spin, use a big pipe wrench on axle to help keep from turning. If it doesn't come loose then, apply some heat to nut and shaft, if that doesn't work cut nut off with torch. Good idea like someone else said, cut washers from old blades if needed.

Pretty much done as the others say. Although I normally take the whole gang off the frame then tear it apart. Probably a little more work but seems easier to deal with it for me.

Back gang you CAN change blades without taking the gang off of disk as there is nothing to stop axle from sliding out, NOT SO with the fronr gang, the axle will NOT slide out due to hitting the one on the other side.

Even though dad had a big 3/4" drive socket set back in the day it seemed we often had to use a pipe wrench on the axle nut as well. Only thing we had that would fit some of those very large axle nuts.
