Green, Wellllllll I used to buy n sell those pony start diesels years back and most alllllllll were bad to throw a ton of blue smoke n a bunch of blow by butttttttttt they usually got the job done. The advanatge was regardless how cold so long as they didnt run out of gas they could start the diesels cuz their exhaust gasses circulated in the diesel head area to warm up it and the intake air. The disadvanatge is they are pretty well all worn out (smokin n belchin badly)unless they have been overhauled and that can be veryyyyyyyyy expensive.

The electric starters do pretty good IFFFFFFFFFFFFFF you have big heavy honkin batteries and those 24 volt systems are still workin WHICH MANY ARE NOT LOL cuz they are complicated for those electrically challenged individuals. Even if all is well it can be tough to impossible to start an elec start model at extreme cold temps where the pony still can.

If I had a limited budget Id rather buy an elec start model then one with a worn out pony motor cuz that can get expensive to repair buttttttt If it had to start at extreme cold temps with no heating provisions then one has to go the pony route

Pony motors do take more care and can be an expence, but a good running pony is always more reliable. Besides, who want to work on a 24volt system. Stick with a pony motor, keep it tuned up and it will serve you faithfully for many, many years.

I have a pony 830 and spent about $3500 in parts rebuilding it. Yes it is neat and is a great way to start during colder weather, but I would never buy another one that required rebuilding. I can buy a lot of batteries for $3500. I also have an electric start diesel 730 and although it needs to be plugged in if you want to start at lower temps, it is much more practical in today's world.

Have a friend that converted his pony start 820 to EC just uses one group 27 bat. & reduction starter off 8000 JD series....has no problems starting in 20 degree weather....soon as I get time my 820 will be converted to ES also...talk about cold starting my pony won't think about starting below 40 degrees ..take care

If you buy one with a pony and it needs a rebuild, I can help you cut the cost on it. Earl In Illinois

I jumped on the 720 on a cold Canadian day today. Starting engine fired right off, rotated the diesel without compression until it had oil pressure, applied compression for a couple of dozen rotations to build a little warm. Advanced the throttle off the stop position and she barked to life.
On a large displacement diesel with only two cylinders.With those massive compression strokes being adjacent without a pause between to give the starter a chance to recover some cranking rpm.
Rare is the person who installs large enough batteries, cables and starter motor for reliable starts. And keeps it maintained.
