I have this 650 John Deere with a 2cyl. diesel engine. It starts real good when it is warm, however, when it is cold especially under 65 degrees it is almost impossible to start. What is the reason? And what can I do to remedy this? I have installed a new preheater but that does not solve the problem.

Did some checking today. Tested the Themo-start device. After testing it I find that the power goes to the unit, however the unit is not functional, so will have to get a new unit and install that.

Thanks again

That device is not needed until REALLY cold ! It should start on it's own pretty easy down to freezing temps. You were saying yours starts hard below 65 degrees.It should pop right off anywhere near that. That device is to ignite a little bit of fuel to burn a flame in the intake to preheat the air. At least that's how I understand it from the books I have on the 750.

Alright, my bad. I thought the small tractors were all 3 cyl. Learn something everyday. :lol: The original post said it was a 1969 which doesn't seem right.

Could someone post a picture of the 650 tractor being discussed here?? The only 650 that shows up on jdparts is a small utility tractor, 80's vintage with the 3 cylinder Yanmar.

Thats the tractor but the 650 is a 2 cyl. The 750 is the 3cyl. Same bore & stroke just one more if I remember right. They used to be in the same parts book.Maybe they are on line too?

Those are late 70's to mid 80's No glow plugs,but pre combustion chambers. Engine could just be worn out ? They should easily start even down to freezing. We never had our 750 out in the real cold temps. so not sure how low they go? Never have used the intake preheater or the block heater.
I would want to do a cmpression test on it. How's the cranking speed? Air & fuel filters? Valves been adjusted and injectors tested every 500 hours? Some of this simple stuff could do it.

Bought a 2020 4 cyl diesel that wouldn't start without ether at 65 degrees either. I had the pump rebuilt and it will start at 25 now with no ether or glow plugs. Can't beat a proper working pump. Had the injectors rebuilt also.

2 cyl??? Preheater????
Not sure what you mean. Should be a 3 cylinder Yanmar engine with glow plugs. Most likely the glow plugs aren't working properly.

It is a Yanmar 2 cyl. diesel. The tractor is about a 1969 model. The pre-heater is in the fuel system before the injectors. I have power to the pre-heater (not sure if that is the correct term for it). I did replace the pre-heater after I bought the tractor hoping that would solve the problem, however it has not.

Emil, are you getting 12 volts to the pre-heater when rolling the key to pre-heat? are you getting fuel to it also?

Shoot me your email and I'll forward a PDF of the Deere tech manual for it. It should help you pin it down

I Checked with a light tester and I have power to the pre-heater. Will check it with the meter as well. Have an 850 amp hr. 12 volt battery to give it a good turn over. When it cranks I have a lot of black smoke and sometimes it sounds as though it will start, but does not quite make it.
my e-mail is: eesy@embarqmail.com

Thank you
