Dutch,
Thank you, again, for your great info. Although my 4115 rarely smokes much at all (180 hr.s now since June), the weather is turning colder. So, I will take the advice to use the pre-heater. I had my owner's manual for a week before they were able to deliver the tractor and I read it cover to cover (and several times since as I do my own maintenace as much as possible). I recall nothing mentioned regarding pre-heater.
I wonder if J.D. thinks that the safety checks (turn key to start while not on seat, then in gear, then with PTO on...) are likely to be performed every time you start up....thereby engaging the "pre-heat" sufficiently? If just an oversight on J.D.'s part, they should send out a note to owners, explaining what you have explained.
Again, these forums are a treasure for a novice, such as myself.
Thanks,...Tom
