Sam, did I hear you say 'choke' when you were starting that 656? It's a gas tractor? I used to manage a farm down in southeastern Pa. that had a diesel 656. I swear that was the coldest blooded engine ever made. Even in July you had to lean on the glow plug switch for a couple of minutes or it wouldn't start.
Stay warm,
Dale
Dale, yep an old gas engine tractor. It's a beasty little machine!
We use a JD 7510 for winter loader work and it has been a great starting tractor. Popped right off yesterday.
Speaking of yesterday, this was the coldest spot I found.
-34F ambient right now.
-55F windchill.
