    Pony motors are very expensive to fix. Period. The parts are getting very hard to acquire.

    Perhaps convert it over to electric start? That could be an option. It’s a lot more convenient and parts are fairly easy to come by.

    Do you know what’s wrong with the pony? I’d prefer a pony myself. It’s just super cool and you don’t see them all the time.

    There are advertisers in Green Magazine and I presume other collector magazines who sell parts and rebuilt pony motors. They also advertise electric start conversions.

    Our neighbor had a 70 with a pony motor,, the pony would not run,,,
    so,,,
    he hauled in some dirt, and ALWAYS parked the 70 at the top of the mound,,

    He would "catch it in gear" rolling down the mound,, it ALWAYS started,,,

    The tractor used so little fuel,, it could idle through lunch,, and burn what? a pint of fuel,,,

    WAY cheaper than fixing it,,

    In the half dozen years I ran an 820,, I do not remember EVER stalling the engine,,,
    Some of the tractors include JD 4105, JD 855, JD 650,,,, and,,, the IH 584 4WD
    My favorite attachment is the homemade landplane,,, EVERYONE needs one of those!!

    You can get a rebuilt cranking engine for $2000, you can start there as far as cost. The max I will pay(have paid) for a 70D is $3500 that is straight and runs well (farm fresh). I will not even look at one that is not original or obviously been messed with. I currently own three of them and know of collectors that have dozens. You gotta love them, they will not make you rich.

    You can buy a nice 70D around here from about $3500-5000 depending on condition, tires, pony or electric. They don’t hit the market often and they don’t typically move very fast either.

    Ive got that one on my watch list too haha, but im not gonna compete with you, i already have a couple and i am not driving that far.

    That said, a couple things, humbly speaking.

    It just says it doesnt run, not that it needs rebuilt, huge difference, i would bet a dollar if you change the points and condenser it would probably run. My guess is someone started it up and forgot to turn the ignition off and burned up the points etc. Once you replace them, install an oil pressure switch/cutout relay, so when you forget to turn it off it wont burn up the electrical. That is the same point in time in which you WANT to get the red jewel ON light working hahahah

    Part 2, yes, pony motor full rebuilds can be expensive, but just jumping in blind will cost you more, so it pays to open it up and actually see what you have going in. I personally like HandJmachining.com

    If you get that one for 1000 bucks delivered a couple things i would suggest, one of the reasons pony motors die is because they run very short periods of time at 5500 rpm, those little buggers scream for a minute, then get shut down. Every once in while, leave your diesel fuel shutoff - off, and engage the pony with the tractor in gear and work that little engine. Let it get up to operating temperature for awhile, the other thing is play with the linkage a bit and let it be more than idle and wide open. Its all relative to extending the life of those things. They get a bad wrap, but i think thats mainly due to people not really understanding that you can modify stuff to extend life.

    Ill be askin if ya got it bought! i have a 70 diesel standard and a 70 diesel r/c, i dont need another one haha

    You can also install a big truck 12v starter, i cant remember which one it is, ill try to dig up the numbers again, but you can build the bracket, its not a bad way to go as long as you dont make it look all butchered, but i kinda like the ol ponys, they are just funny to me i guess. I wouldnt spend the 1800-2000 that some people are asking for the "upgrade" kit
