Caroni Finish Mower Pulley

[JCinKY]

I got a 5' Caroni mower last summer because it was cheap. Its in really bad shape and I am going to completely go over it and fix it up for my dad.

So far I have cut every nut and bolt off it to get it down to the bare deck. The gearbox and support arms came off easily, but I cannot remove the spindles due to the pulley. I noticed it has slottled 25(?) mm nuts. Is there a spanner to remove these? Other special tools? Big pipe wrench? Any help is appreciated.

Your description comes out a little vague. I can think of two kinds of "slotted " nuts. One that we usually call castle nuts had slots that you put a cotter pin through, or lock-wire if you were working aircraft. The other is a form of self locking nut that I suspect Caroni might use. The slots actually are crimped in slightly to self lock the nut. Nothing special to undo, just a bit extra heft on the wrench. They do tend to tear up threads so you might consider replacing the bolts. Pay attention to the bolt head markings. They are metric and they will indicate the grade of bolt.

Yeah I guess I strayed a little off topic there. The nuts I'm talking about are holding the pulley to the spindle, in that the nuts are on the end of the threaded spindle shaft itself. They are not castle nuts with a cotter pin. They are not self locking (crimped to my knowledge). The are not hex but round with four slots in a cross pattern.

I will try to post pics later and that should help.

Is the picture below the nut? If so, I think an adjustable spanner
wrench will take it off, if not rusted too bad. If worse comes to
worse, you could try backing it off with a hammer, and punch, or
cold chisel. You will likely need a new nut, if you booger it up,
though.

Make your own socket out of a piece of pipe or thick wall tubing. Find some that is about the same diameter as the outside of the nut. Lay out where you want the notches with a Sharpie or some paint or scribe. Hacksaw down the side of each notch and grind out what is between notches and you have your own special tool. weld an old or cheap socket to the top of it or weld a fairly big nut to the top and use a socket on the nut to drive the tool.

I hope I made sense with this description. I have done it several times over the years.
