I have a 300 utility with approximately 100hours after a rebuild. I purchased it this summer following the rebuild. It has been converted to a 12 volt system.
It will crank up immediately when it has been on a battery charger. I can use it for awhile and then it seems to start to lose horsepower and begin to become extremely touchy at the throttle, or it will cut out.
The alternator belt is tight, and there is not any excessive noise.
My theory is that it is only getting a trickle charge and that toward the end it does not get enough spark.
I have fresh gas, and have changed the sediment bowl.
Do I take it in for a tune up already, or take the battery to have it checked, or call my snowplow guy to kiss and make up after I told him he wasn't needed ?

Thanks

I've got my H, M and 300U all switched to 12 volts and about once a year they start getting the symptoms you discribe. I put in new points and condenser and the problem is solved. If you don't know when the last time your tractor had new points and condenser I would try that since it doesn't cost much. A bit more expensive problem could be a coil going bad. When they go bad they often work until they get hot, then they don't work very well. You may also want to make sure you're getting enough gas to the carburator. When I got my 300U it had enough junk in the gas tank to partially plug the outlet from the tank.

Thanks guys.
A trip to the auto store for new plugs and all the distributor accessories was what apparantly was needed. The frame from the loader made getting into the distributor more of a challenge, lucky for me there was time over the holidays.
I did note the when putting the coil wire into the new rotor cap that the wires under the clip were minimal, and that they were not laying the length of the whole clip, so I got as much in contact with the end clip as possible and stuck it into the coil hole.
It fired right up, and was immediately more responsive. Alot to be said for regular maintainence, and dry gas.
Thanks again, Jerry

Jerry, it is my humble opion hat there is something else wrong. Will the tractor turn over after it cuts out? Can you jump the tractor and get it started? If you jump the tractor and it will turn over, is trying to fire? What I am thinking is that you may have a coil that is shorting out after it warms up, but I need more information. If the tractor can be jumped, then that tells me that the mechanical side is not tighting up, which is good news. Electrical problems are difficult to diagnose, but not impossible. You probably have several problems, lets attack them one at a time. First lets get the snowplowing done, then let's address the issue of not having to use a charger all the time. Once you get the old girl fire on all clynders you love her, but like any wife/girl friend they like a little attention.. Also, as a Farmall owner your are forbidden to Kiss the Snowplow Guy... :-)

JERRY I THINK YOUR PROBLEM IS IN THE POINTS OR COIL.TO MANY AMPS TO THE COIL .IS IT STILL A 6 VOLT COIL? IF IT IS CHANGE IT TO A 12 AND I THINK YOUR PROBLEM WILL BE SOLVED.YOUR POINTS ARE PROBLY ALREADY SHOT SO THAT WOULDNT HURT EITHER.PUT IN A BALLAS RESISTER THAT WOULDNT HURT ITS LIKE INSURANCE.AND RUN PREMIUM FUEL THE OLD GIRL REALLY LIKES THE OCTANE.PUT ABOUT 600LBS ON THE BACK IT CAN HANDLE THE EXTRA WEIGHT WHEN YOU GET THE OLD DANCING GIRL POOPING ON ALL [4]I GOT ONE SO IM SURE OF THIS;
