A couple 3 question to the form please from a new user.

I have a Harry Ferguson that has a Ser # TO- 130236 on the placard at the steering column, do I own a TO-30?

The placard on the block # Z129-371969 is this a 1969 model?

I am going to purchase a new gas tank Part Number S.43668 from Yesterdays tractor is this the correct tank?

Last question what is the advantage in switching from 6 to 12 volt? thank you
 
You are correct on the TO 30 wrong on the year. The TO 30 was built from 1951 through 1954 yours is a 1954. Yes that is the correct part number for the fuel tank.
 
If your battery and generator and voltage regulator and all your connections are in good shape, clean and good contact, and you have the
large (no. 0 or 1) battery and starter cables, then your 6 volt system is good to go and it is not worth converting to 12 volts IMHO.
However, if you are having trouble with the system and you need a new battery anyway, ... then you might want to consider converting,
especially if you use the tractor in cold weather. This site sells a very good conversion kit, complete with alternator and
instructions for the TO-30 (it doesn't work for the 20 as the alternator bracket is different). Of course the battery and 12 volt light
bulbs are not included in the kit. All said and done, with lights, you will spend about $250 on a full conversion. You can use the old
starter, but don't grind on it too much. The starter doesn't care about polarity. Hope that helps. Remember the battery is about 44%
of the total cost, so consider a conversion more seriously when you need a battery anyway.

thank you for the info, our TO-30 has been in the family apparently since 54 the wife's grandfather purchased it new so we will probably leave it as is for now.

Switching with nothing wrong means you spend more money for nothing. 6V works just fine. 12V makes the starter
spin faster. That's about it. 6V pos ground makes a hotter spark at the plugs. That's all.
6V dead battery? Jump it with the 12V car. Pos car battery to pos tractor ground(foot-peg). Neg car ground to
starter lug. Out of gear, choke set, throttle set, as son as you contact it, it will start cranking.
Wow. You just made 12 V work on your 6V tractor.
 
Yeah, if it's working good, don't mess with it. I like 6 volt systems just fine, but you do have to keep them in good shape. The 12
volt tractor will overcome some issues the 6 volt system will not, especially in winter and after sitting long periods. Bruce is right,
of course. You can jump a 6 volt with a 12 if you go directly to starter and ground (out of gear). Which cable from your vehicle or
battery source goes to starter doesn't matter. I carry one of those 12 volt jump start boxes in my car most of the time for just that
scene. Also, Sportsman Guide sells a good 20 ft. jump start cable in a large diameter, much better than the wimpy ones at the parts
stores.
 
It's been along time since I owned a
TO30, used to have three at different
times, if I remember correctly the
easiest way to tell a TO30 from a TO20
was by looking at the oil filter
location, the TO30 oil canister was on
side of the engine block and the TO20
was underneath the tractor in the oil
pan, someone correct me if I'm wrong,
been several years since I last had
one...
