Well bought a new battery and cables for the Cub. Nothing. Took the switch off starter and tested it. and it's OK. Tried a direct jump from the battery to the copper lug on the starter and still nothing. Took it off the tractor and took the band off. The brushed are down to the nub. Worn down to the mounting tabs. At least it's a start on the road to repair. BUT, we have only a couple guys left in town here who know much at all about the old things, and I will contact them tomorrow. But if they can't , won't or whatever , is this a DYI project ? I've seen some kits for sale with new brushes man the like but just wondering how hard it would be to do .
you can DIY if you have a fair amount mechanical ability , not a difficult job

Almost as easy as changing the oil and filter. If the brushes are down like you say, you certainly need brushes, which is an easy fix. Let us hope that there was not too much arcing on the commutator before the generator shut down. Not that big a deal either, except that the commutator may need to be turned on a shop lathe. The generator is built like a military tank and very forgiving, so chances are a little dressing up of the commutator and new brushes is all that you will need.
Commutator looks good, no damage seen. I've rebuilt carbs,rear ends , etc but just never got into the electrical motor stuff. I'll check the old guys ( I say "old", they are not much older than me,LOL) first and if that does not pan out,I'll give it a go.
most any auto elec shop should have the brushes.

Welcome to the forum. Just a thought on the new battery cable. If your cub is 6V the cables need to be a little heavier than standard 12V car cables that you can get almost anywhere. I think those are 4AWG. You should have 2AWG or even 0AWG cables on a 6V system. The smaller (4AWG) cable can work on 6V, but not well, and will eventually cause you starting problems.
Yep, I'm pretty well versed on 6 volt systems. Just finished a body off restoration on a 1950 Crosley which included a complete rewire of it's 6 volt pos gr system. When I done the Crosley I bought a universal 6 volt harness from Rebel Wire. Being universal it was made to work on the biggest 6 volt car ever made. I think I have enough heavy gauge wire left from it to rewire a couple Cubs. We have a shop here that makes up cables to your specs.
