Hello All,

Just brought home a 140. My grandfather had a cub when I was a boy, but he always talked about moving up to a 140. So, here I am bringing one home to the farm after all these years in his honor/memory. I just ordered an operators manual.

As I get started with it, can anyone share experiences with jumping off/charging the 6 volt system. Drove it off the trailer last night. Didn't want to crank this morning. Was in the high 20's last night. No surprise on turning slow.

No experience with 6 volt system, nuances, positive ground, etc.

Any assistance input is welcome.

Thanks and have a great day!
 
You'll need a 6v and 12v dual charger
to charge the 6v battery (not sure
they even sell just a 6v charger
anymore). Just put charger on the 6v
setting (or some of the new chargers
do it automatic).
When hooking charger up to battery,
just ignore the tractor cables, and
hook red from charger up to + post of
battery. And hook black from charger
up to - post of battery.
If your 140 is positive ground, the
tractor ground cable (hard to tell
what color it MIGHT be), will be
hooked up to + post of battery. But to
avoid confusion when hooking up a
battery charger up, just ignore the
tractor cables, and go by the + and -
marks on the battery itself.
As for jumping, you basically do the
same thing with your jumper cables,
and go by the battery marks (you
should only be using a 6v battery for
a jumper battery, not a 12v). Not that
you can't use a 12v to do it, but you
will risk frying a voltage regulator
or something else on the 140 if you
do.
 
IF the cables arent any good and the battery is shot and the connections are dirty 12v doesent work either so strt with the
battery read the cells with a hydrometer then clean the connections on both ends and if things are up to it will start and
run just fine. Just how did we get along with them when they were new
 
Before you operate your new tractor very much you probably need to
change the fluid in the transmission and final drives. Doubtful previous
owner has done this recently. Check engine oil, air cleaner oil and
radiator fluid. It's cold where you are so check freeze point of
radiator fluid especially if it came from a warmer area. Your owners
manual will explain these things but remember that manual was written
years ago so you need to upgrade some of their instructions.
Enjoy your 140.

Hello JJ welcome to YT! Hopefully this will be helpful, I
will attach a link to the CNHI parts diagram for your
tractor. CNHI is the current name of the company that
owns the ..IH and Farmall.. names at the moment. The
diagram will give you a look at what is inside. If it is not
obvious many parts are no longer available. Sometimes
it helps to actually web search the part number for the
parts that are difficult to find. From this same page you
can navigate to see all the different part sections for
your tractor. Hint, if you have a phone you need to hold
it sideways to see the navigation arrows. And if you
lose the page just select ..Model.. and type in Your
tractor model, like Farmall - - and Search and it will
come up in the list.
If you are not set on keeping everything original on the
tractor I would recommend that you convert it to a 12
volt system with an alternator and you can just run the
6 volt starter it will work fine. Sure the 6 volt starting
system will work if everything is up to par. Generators
and voltage regulators are kind of troublesome
compared to an alternator.
Also I do not know if anyone asked for a picture but
generally on this site you need to have a post count of
5 to be able to post pictures. This is just to foil some of
the internet trolls about.
Lastly if you send me an email I will send you a link for
a PDF of a maintenance manual for your tractor with
more detail than the Owners manual. It is not a
..repair.. manual however.
Enjoy your tractor!
 
Welcome!

I have a newer 12 volt 140 but my wife was raised around some 6 volt Farmalls. From my understanding, the 6 volt systems need a heavier cable to the starter than newer 12 volt systems. If somebody put on a smaller cable, it can be difficult to start at times.. check the ground wire from the battery to be sure it is making good contact with the tractor chassis.

My experience is to get OEM parts where possible. I have found some third party replacement parts do not fit or fit properly. I experienced an upper hose where I needed to use OEM. I was able to make my third party radiatormwork with some modifications.

Enjoy your tractor.
 
What's most important to keep in mind is that there is nothing mystical or magical about 6V. It's the same as 12V, just with 6V. Match your +'s. Match your -'s. Match your Volts. All will be well.
 
Follow Gene Benders advice. Check the condition of your connections and the charge / health of the battery. Dont know where you are, but cold temperatures will identify any weaknesses in your starting system. Your battery could just need a charge. Like any battery in a vehicle, if it sits for awhile it will lose charge over time. I have a 6v and it will start easily when it is cold if everything is correct.
