Link to alternator conversion AC 620?

Recommended Posts


I still have my 620, however it is in pieces after a couple of years when I was working on replacing melted wires.  Life gets busy you know?  While it's still winter, I was hoping to get it put back together.  I haven't taken the time to get back to getting her back together again.  I recall that I was thinking about putting an alternator on it as I had a problem with the battery not charging.  I recall someone had a link to how they fabricated an alternator setup in their 620 or 720?   If it's in the technical area, I did try to pay my dues, but the site wouldn't let me order for some reason.  But I digress...  

Another thing I'm wondering about is the tensioner pulley down in the 60" belly mower.  I recall that the the spring seemed rather weak and when I would get into some tall grass, the mower would not really cut all that well,  and I would have to take my time getting through it.  Anyone have a fix for this?

@720nut can help you with that.  Hopefully he will chime in on his install.

Is your stator the current problem?

If that is your problem, they can be rewound.  There are a few places in WI that will rewind them for you with a core.

Thanks guys think my post pretty much explains how I did the alternator.

I've done several of these builds , even run one on my pulling tractor to keep Braile battery I use charged

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time

      I assume it's a bosche, correct
