Helping an older friend that bought the tractor new in 62. The tractor has been converted to 12 volt and has an alternator. The tractor has also been conveted to propane. A few issues in getting ths tractor back in service are.
1. A new/rebuuilt starter was installed and the starter will not disingage when trying to start the engine.
2. There is a shock when the starter switch is depressed.

He has asked me to get the tractor going. Any advice is appreciated.

We've not much information, CM but I can offer a bit of advice.

If the starter does not "disengage" after the engine starts, you should inspect and/or replace the starter drive (sometimes called a Bendix).

By "shock," I assume that you mean a mechanical shock or impact. This is normal on 6V systems that have been converted to 12V unless the starter has also been converted to 12V, which is very rare. Indeed, the impact loading resulting from operating a 6V starter on 12V results in long term durability issues with the starter drive and flywheel ring gear as well as other, not necessarily long term issues with other components in some designs, notably, starter "nose cones."

As a matter of curisioty, I have never before heard of one converting a vintage tractor from gasoline to propane, though it is not uncommon for one to convert from propane to gasoline. Why did he do this?

Maybe it"s actually a factory LPG- not a conversion.

I say converted because the fuel tank has the top cut out and is used for a tool box. The propane regulator is to the R/H side looking from the front and the fuel line inlet to the down draft carb has a plug in it. I figure it was converted because propane was much easier to come by in his part of the country in the 60s. He would have no discussion of going ot gasoline.

I have not started the tractor and am going on discussion with Mr. Ted. I'm thinking the battery cables were crossed and the solinoid shorted like I did on my welding machine. A solinoid is cheap enough to buy and check, or I should be able to by pass the starter and crank the tractor from the battery.

The only other tractor I have helped convert from 6 to 12 was an old 9N and put an ignition switch on it, but had no shock. I thought maybe the coil had to be involved to get an electrical bite. Need to correct that problem as my girl is planning on using the tractor for bush hog work..

Bt the way, the starter is suppose to be a remanufactured. Don't think the tractor has ran in better than three years.
