@hosspuller - got it, makes sense
@MTGreen - awesome, super helpful info
@Robin Veerman - thank you. I've ran it a ton all summer so bet the old fuel (if any) is long gone. Also, live in DFW...I'm not sure they even change diesel formulations here lol
Guess I know what my next project is...
Got it, I will give both of those things a try. One more question: If the valves are out of adjustment, is the thinking that it would be creating too much compression, which is therefore slowing down the starting speed?
@Harry - I changed the fuel filter in September and this problem just started in November/December

@grstrom - Yes, I've tried multiple throttle positions

Answering Q's in-line below:
1. Engine model: Yanmar 3TN75RJ 1.0L diesel

3. Valves: Unclear when they were last adjusted
4. Air cleaner path: Will check and report back.
5. Air...
Hope all is well! I have a 1987 JD 855/856 compact utility tractor that has recently begun to be very hard to start first time in the day. It has 923 hours on it and a known history back to 2001-ish and has always been maintained well.
The tractor was used all summer for some general property...
