I talked to my dad because he uses the tractor more than I and he gave me some more info. The 1750 has to be started with ether when the engine is cold-summer or winter. If you work the tractor and shut if off and try to restart immediately, you have to use ether. But if you work the tractor, shut it off and come back 15-30mins later the tractor starts without ether. thanks again for the replies
