6V starter, 12V battery?

Tue Sep 07, 2004 1:37 pm

In looking at the pictures on the TM Tractor gallery, I would swear I've got a 6V starter, and a 12V battery...

I say that because of the different circumferences of the 6V vs. the 12V device, and because I can't find a picture of a 12V device with the trademark "telegraph button" starter/actuator on the side of it, which I am certain mine has.

I'm not entirely certain until I get home tonight to look at the tractor - but I'm assuming that that's "all kinds of bad."

Allenlook, most conversions to 12 volts do not include changing the starter. The 6 volt starter motor will operate quite well on 12 volts. Just remember not to crank for long periods of time to avoid overheating the starter.

Thank you!

Thanks BD... It's good to know that it won't just "smoke" it some idle Saturday when I'm counting on getting some work done. :shock:

And I'll be very sure not to crank it over for extended periods (which hopefully won't happen anyway, Jay seems pretty happy to fire right up every time I pull the starter rod.)

By the way - I've been meaning to offer my condolences to your dog (in your avatar picture)... It must have been a horrible accident to lose both his ears like that? But he seems to be taking it well. :D

Just seconding the "it'll work fine on 12 Volts" notion. With 12 Volts, the spark is so much hotter and the tractor spins over so much faster that starting is rarely an issue. My Dad's Super M spins over so fast that it won't start unless you release the key and let it slow down! :twisted:

Matt, I have found that when you are dealing with tractors that have magnetos, there is an advantage to them cranking over more slowly. The mag impulse will not function when the engine is cranking over quickly and you lose the benefit it provides in starting.

My '57 turns very slowly, seems like it should turn faster. The starter sounds like its wearing out.

Oh, heck. I've got a pretty darn fine starter/battery story.

My Dad had what we think (we don't have it anymore) a '46 Cub with no documents or anything. The one thing it had was ALL of the cultivators down to the last nut and bolt, but I digress...

Anyway, Dad would never fix nothin' if it was gonna cost a dime. A carb rebuild kit was something like 18 bucks at the time but would he fix it - nope. Why fix it, was the reasoning. The gas stopped pouring on the ground once the tractor started....which leads to the story.

He also broke the starter rod/button hook up and wouldn't replace it - don't recall but he might never have had it in the first place. He also apparently never knew the tractor had a positive ground. Besides the fact that I now wonder why it would turn over at all with the battery backwards :? , he used to take the bare cable and touch it to the starter contact to start the tractor which it would - in an absolutely wonderful shower of sparks that were like July 4th....especially beautiful in the snow :roll:

Well, sparks, gasoline flowing out the dripping carb...you get the picture.

He never blew anything up or caught it on fire, but you can bet your last Cub dollar that I used the hand crank to start that tractor up!!! :)

Memories like that contributed to purchasing the Cub in the first place. Seems like you just have to have one around, you know? Let's see...there was the cobbled together snow blade, poking a stick through the radiator while pushing a brush pile with said cobbled snow blade, cracking the rear end housing trying to pull a boulder the size of a small house... And I wonder why I bought one! :{_}: Heck, all I've got is rust and a balky clutch - where's the fun in that???

Dad ended up trading the tractor for a woodstove...danger never diminishes, it just changes form!!

That sounds alot like the kinda of stunts my dad pulled.
