I have a 67 4020 Diesel. This tractor is my pride and joy. It is the factory 24v split 12v system. As any one with this system knows the generators don't charge very well. This tractor is not my primary tractor I use on the farm So it never really has time to charge. Anybody have or know of someone who has bought the alternator to generator conversion kit from deere to know if it is worth the 200 bucks? And don't tell me to convert to 12 volts. It's pricey and a neighbor down the road bought the 12v conversion from deere last summer and now his tractor wont hardly start in the winter because the starter doesnt crank as good

There's really nothing wrong with the 24-Volt system OR the 24-Volt generator, UNLESS you have a lot of 12-Volt (-) ground accesories you need to operate.

The 24-Volt generator only puts out about 1/2 the Amps that a 12-Volt generator does, but taking into account it's at 24-Volts, the generator actually DOES replenish the batteries after a start as quickly as a 12-Volt generator of twice the Amps output does on a 12-Volt system.

I have a 24-Volt 4020, and I gathered up all the parts I needed to change it to 12-Volts. I repair tractors and alternators. After seeing some of the messes people create for themselves converting to 12-Volts, I realized the 24-Volt system isn't so bad, after all, and didn't convert mine to 12-Volts.

Get a GOOD pair of 12-Volt batteries. Get two 12-Volt "float" battery maintainers... about $15.00 each @ Waldo World. Connect one to each battery, matching the maintainer's polarity to that of each battery. When the tractor won't be used for a while, plug in BOTH battery maintainers. If properly connected to the batteries, EACH will keep it's battery fully charged, and they will NOT interfere with each other.

Problem solved, for less than $50.00.

Email me with any questions.

10amp 24V generator = 20amp 12V generator.
It would help if 12/24V owners used a voltmeter and set the regulators to 27.6V instead of taking a w.a.g. It would also help if they wern't so d*mmed cheap and shut the tractor off for the minite it takes to close a shed door or open a gate. A battery is like a bank account. Take more out than what is put in.Things won't work.
