Also getting ready to paint a 8N Ford Tractor…which company is a good source for authentic FORD spray paint in spray cans ?
Menards carries both Ford red and Ford grey. The red comes in a spray shaker can and the grey comes in pints. They are the authentic colors. It’s expensive but it’s good hard enamel paint. I spent about $200 to cover my tractor but it has front end loader. it probably would have been a little over $100 to cover the whole tractor
Where do I find the port to add brake fluid to my 49 Ford 8N Tractor??
what is the rated capacity of this ford 8n tractor? like towing or pushing capacity in thousands of pounds? can not seem to find it. thanks in advance.
We have an 8N and for the longest time, the positive side of the battery goes to ground and the negative goes to the starter. Its always worked this way but is this correct?
If it works, don’t change it! I’m sure you won’t anyway, without doing research. I will consult my 8N manual and look at my 8N when I get back to it next week.
This is kinda dating me(old,but not as old as thes tractors!) Many of the cars and tractors from the 20’S to the 50’s we’re 6v Positive ground systems,growing up we had 49 8N w the step up trans and Dearborn lift ,I converted it to 12v neg ground and used a internal regulated Delcotron alternator after that it would start easily even coldest winter,I would plow drivways all day back then!
how much can a ford 8n front loader bucket lift
8n is a positive ground.
