Your battery loses approx. 1/2 it's amperage in freezing weather, so you need the biggest CCA battery that will fit. The battery must have at least 12.4 volts and maintain about 9.5 volts when cranking. If you do not have a volt/ohm meter you will need one to successfully maintain your tractor. Are you aware you must start with wide open throttle?

Even if you use a Volt Meter and it shows 12V. doesn't mean the battery is good. If it was mine all the Battery connection are clean Id
swap it out. If you can't do that have it tested at a local Auto parts store. My bet still that's it's bad. I've had them go out when I stoped to get gas and my Truck wouldn't even jump off. New Better and called the Wifey to bring me a new battery and it's still in my truck today.

You can put a volt meter on the battery as someone turns it over .. You will be able to see how much voltage drop you have... With the decompression lever pulled or turned (how ever yours operates) the engine should turn over very rapidly ,because you will have no compression for the motor to be turning against. If it doesn't turn over real easy with the de compression engaged ,, something is not right... 15W 40 oil should be in the engine.. In the winter 15w40 oil is thick..I have 850 CCA battery.. When it's cold out I have a tough time getting my 3110 to start..If you have a way to warm the engine block (flood light etc,) will make a big difference

It's the CCA-Cold Cranking Amps. Not Volts. That's What you need to get check. It may show 12+V just like I said. But if the AMPS are weak that could be the Problem. It ran a couple of days ago so Oil is doubtful. Maybe anything is Possible.

But, If it goes from 12 v to 5 v when he tries to start it. It ain't going to have many CCA..Just replaced the batt in my boat..800 CCA.. When I tried to start with old batt. the boat , voltage would drop to 9 v hardly turn over.. So, if he ain't got 12 v it ain't going to turn over well,because he isn't going to have xxx CCA either

I went down to my work earlier today and got a jump box and hooked it up to the tractor and i still could not get the tractor to start. Its seems to turn over fine until the compression is engaged back in then it seems like it cranks really slow. While cranking i have very little puffs of white smoke coming out of the exhaust. But nothing else happens. Could it just be so cold that it wont start, the temps in northern Kentucky have been single digits at night and teens during the day. But like i said earlier i had it running a few days ago. Im going to try this weekend when i have more time to wrap it in a tarp and put a heater under it. I have no idea what the problem could be with this thing ive only owned gas tractors before this one so this is my first diesel. So i would appreciate any help i can get. Also one thing I forgot to mention was i noticed when i was cranking on it was one of the wires tied in with the positive wire coming off the battery to the starter got red hot and smelled like it was burning could it be a bad positive wire

Cables can corrode under the insulation. I had one catch fire while jumping a tractor

kenmac · Feb 18, 2015

You are going to have to warm the block up.With a heat lamp or by some other method. Or wait till it warms up. While you are cranking ,don't stop and push the decomp back in .Push it back in while the engine is still turning over. The red wire will get hot if you continue to crank on the engine.. I have melted the insulation off mine B-4.. My diesel truck has a hard time starting with 2 batteries and an intake heater, if I leave the truck out, and it gets in the teens

Any chance you removed or placed the fuel filter and didn't bleed the fuels system?

I have a 1500D also. Kenmac is right. You need to warm the block. I have used a bullet heater before to warm it up. I have managed to install a lower hose heater on it. If I plug it in for a while the tractor will start right up like its a summer day. The next thing I would suggest for the tractor is gauges. But that's just me.
