580ck 'b' pedals

Have an old tractor with hoe attachment. It is a 72 CK 'b'. I am not exactly sure what each of the pedals is for. I have three main pedals. One to the left of the steering column, this is for the left axle brake. I then have two on the right. The one closest to the steering column is for the right axle. I am unsure what the outside pedal is for.

I also have a 'plug' type lever on the foot rest for the right leg. I think it is for the lockout for the differential, but when I depress it, it locks and is difficult to get it back up. If I press it down, I have to climb under the tractor to get it back to the up position. Any suggestions to what it is for and if it should be in the up or down position all of the time? Thanks in advance.

Can I ask how much you paid for your 580B?

I have one and am thinking about selling.

Paid $6500 for it. I wouldnt recommend to anyone buying something like this. With the economy the way it is, you can buy a tractor that is in mint condition off lease for $10k from any Case or Cat dealer. It may be 10 years old, but the one you buy would be easier to use and in way better shape than any 30 year old one would be.

Mine is a diesel. I have close to 4K in it. The newer ones have better sight lines for grading and many other technically better features than the older ones.

Hope I dont steal any of your ideas Tim.
