Depends on the engine and situation with the ether. Also depends on the procedure. Alot of tractors came from the factory with ether inducers built in for that super cold start. Sometimes the block heater/tank heater wasn't enough. On the 806 or 1206 that needed a little help when cold, we'd get the engine turning over, then hit the ether button for a very short time. It would pull in the ether evenly so to speak. I cringe when I see these guys hop on a tractor. Push the ether button for 20-30 seconds, then hit the starter.
Poor tractor. A little goes a long way. We usually would plug the tractor in hours before we needed it and it would start without anything. Never use ether in glow plug tractors.
Todd,
Thanks for the picture clarification.
Jonathon,
Thanks for the info about the early versus late 782D changeover.
