just picked up 1964 cub lo boy

Postby torino » Thu Aug 31, 2017 9:12 am

oI just picked up a 64 cub loboy with the offset steering wheel so it is just the loboy model . It is yellow and white and the first year with the new style grill and hood. My question is ? is this tractor a 6 volt or 12 volt? positive ground or negative ground. I put a 12 volt battery in it with neg ground , it starts and runs fine. after 15 minutes of running it starts to break up and eventually stalls and wont start until it cools down for an hour..The ignition coil is very very hot when it stalls out. This is why I am wondering if its 6 v or 12v or neg or pos ground. serial number of the tractor is 18807j. thank you

They switched over to 12 volts at Lo-Boy 18701. So yours should be one of the first with a 12-volt system. The instrument panel should have a key-operated ignition switch and a big button to engage the starter. The 12-volt systems are negative ground.

Given a 12-volt system, your problem sounds like it is with the ignition coil itself. Most likely, you simply have a defective coil. It is also possible that the previous owner erroneously installed a 6-volt coil. Either way, it looks like you need a new coil.

Jim has you covered with the coil replacement, suggest you go with a 12v internal resistor coil to eliminate the need for a ballast resistor. If you want to check a bit further, when the engine stops, remove the center wire from the distributor cap and with the engine cranking, check the presence of a spark jump from the coil to ground with the end of the wire about 1/4 inch from a clean bare ground point. No spark/weak, yellow spark = bad coil, replace.

Hi,
Welcome to the website.
Below is a 1965 Cub and LoBoy owner's manual, it has info for 6 and 12 volt systems, just use the info for 12 volts for your LoBoy.
They did not make a new manual every year, I have read on here.
The experts on here recommend that people read it, it has lots of info about operation, maintenance, and lubrication. It shows all the fluids that need changing.
The transmission oil is a common one that needs changing, it can get water in it from rain, or condensation over time.
There are also 2 final drives to check the oils in. The trans and final drives have 3 separate oils to check.
There is a table of contents on page 1. :)

Welcome to the forum. Sounds like you've already received some sound advice.

Glen has you fixed up with the Owner's Manual links, but when you have made 2 or 3 posts, you'll be able to access all the manuals for free. They are located via the "Quick Links" pull-down in the upper left portion of the screen, under "PDF Manuals". Let us know how it's going and attach a picture when you get a chance; we'd like to see your Lo-Boy.

THANK YOU EVERYONE FOR YOUR RESPONSES!......I PUT AN AUTOMOTIVE POINTS COIL I HAD SITTING ON A SHELF (STANDARD PRODUCTS) AND STARTED IT UP. RAN IT FOR 35 MINUTES AND NO BREAKING UP OR STALLING. I USED A RAYTEK THERMOMETER ON THE NEW COIL AND IT WAS A LITTLE OVER 100 DEGREES IN THE CENTER AND ABOUT 85-90 TOWARDS THE OUTSIDE. THE ORIGINAL COIL WOULD BURN YOU WITH A TOUCH WHEN WARMED UP. I AM GOING TO CHECK TO MAKE SURE THE CHARGING SYSTEM IS WORKING PROPERLY AND NOT OVER OR UNDER CHARGING. THANK YOU FOR THE MANUAL ON TRACTOR ALSO.

Check for output voltage from the coil you installed. If it is higher than about 5 volts, you need a ballast resistor in line before the distributor connection.
