Can anyone recommend a supplier of 6 volt to 12 volt electrical system conversion kits. I believe its a 1953 Model VA1.

Thanks in advance!!!

Ed

Hey Harvz; There is no reason to convert that tractor to 12volt. With a good, 650CCA 6 volt battery, and new 2/O battery cable, that tractor will spin over like a 12volt. A 6volt system requires larger cable than a 12volt system.

I use this tractor quite a bit during the summer months for mowing and occasionally for snow in the winter. It seems like I'm buying batteries every year and the six-volts don't seem to hold a charge for long. I'll check to see what size cables I'm using. Any additional suggestions?

Thanks for the response John!

Hey Ed; Something must not be right. I've had the worst luck with Exide batteries, and I used to sell them. A good 6volt battery will be around 650CCA @ 0 degrees F. 2/0 battery cable might be a little much for the "V" series but definately 1 guage. I've seen 4 guage for starter cable on 6volt systems and that just won't cut it. How's the charging system?

John, Thanks for tauting the merrits of the 6 volt. VA series tractors are about the easiest starting tractors there are if they are tuned up right. The tractor is running with just a bump of the starter. I've just always seen 12 on these little rigs as overkill. I don't think i've ever even broke a sweat cranking a VAC. My brother made the unusual mistake of hand cranking dad's 46 with it in 4th gear. It fired up on the first roll over and stoped when the front end ran up into the corner of the barn.

I'm not a mechanic though so you keep fielding these guys questions.

Happy cranking

Hey Wheatstraw, Thanks for the comment. That pull of the crank must have felt different with the ole girl in 4th. I trust no one was hurt.

John, Dad had us cranking old tractors early but he had always taught us to make sure its out of gear, the throttle set about a third and stand to the side and pull the crank over from the top. It's obvious which step he somehow left out. He was able to side step her as she snorted ahead. Would make a winning funniest home video if there had been such in them days.
have fun

John and Wheat,

I remember my dad parking the tractor on a hill so that he could get a good start before popping the clutch. When he didn't have a hill, he'd have us pulling the tractor behind the truck (this was back when it was legal to drive at age 12! ;)

Anyway, I picked up a 650 CCA battery with some 2 gauge cables and it fired right up! It getting harder and harder to find 6-volts. Should I also replace the cable from the ignition to the generator? It looks pretty rough! Also, is there an easy check to see whether the charging system is working well?

Thanks for all the help !

Ed
