cold weather starting?

[jiminpa]

what starts when it gets cold and what has trouble? my old mf 35 diesel starts like a gas tractor,but its a 1962. how do the new tractors compare?

My 2013 LS R4047 with a Mitsubishi diesel starts wonderfully. On the really cold days, I give it 2 cycles of glow-plug warming, and it starts right up. It IS barn kept though, but the barn is not heated. So, it's out of the wind, but not away from the cold temps. I don't have any type of engine heater installed. Very impressed with cold starts.

Starts better than my previous Kioti CK20S. Starts better than my old Ford commercial mower with a 3 cyl Shibaura diesel did. Starts better than my current Hustler ZTR mower with a 3 cyl Shibaura diesel.

How cold is cold?

Turbo's have a harder time starting in really cold temps

My 72 JD 820 starts like a champ in cold weather (below 15 degrees). Of course the direct injection port for ether helps out dramatically.

Our VW TDI (turbo) starts like a gasoline engine.

All the diesels I've owned have usually started with the first 1/2 rotation of the crankshaft. The older ones usually shuddered a bit though. Not so this TDI. The (new) 1025 is no different from our 1983 240D. Starts right away but plenty of shuddering and lots of smoke, blue and white. The 240D didn't smoke like the 1025 nor the 4010 though. No smoke at all from the TDI.

Oh, our Isuzu diesel generator doesn't seem to have much shudder and no noticeable smoke. It started on schedule last Thursday in teenage temps. It's about the engine size of the 4010 that I had but much smoother.

Man, talk about shuddering ... my old Ford mower would shake & shudder so much, I'd worry it would rattle right off the engine mounts! Then it would roar to life with a big stinky cloud of black smoke. Lol

Turbo engines are built with lower compression than non-turbos. When cold cranking in really cold areas the, turbo diesel has only it's static compression to compress ( heat) the air fuel while cranking with the starter motor, so it can be harder to ignite than a non-turbo equipped with a higher static ratio.

this makes sense - my 2011 4720 turbo starts fine in the cold (20-0) from inside my shop but if left outside overnight in the wind it takes some cranking and black smoke to get it going. need to keep my battery 100%

I don't know what brand engines you are referring to when you state turbo'd engines are lower compression than naturally aspirated but that isn't true on JD 239 CID(3.9L) engines as both types are 17.8:1 compression.

Your 4720 turbo'd is 20.5:1 compression

 

[9973720wb19]

Is that good?

 

[buickanddeere]

Great unless unless using turbos in series for tractor pulling.

I was hoping I didn't have to get into the whole compression thing again, on this thread. Here's the quick, down'dirty explanation:

Published engine compression ratios are only a static snapshot of the cylinder volume. It's BDC vc TDC. Actual real "working gas" compression ratios may be very different, depending on many vaiables. Most influential, are valve timing, and turbo/no turbo.
My guess is that the tubo version of that engine has different camshaft(s), or a difference in their timing relative to the crank.

First off YOU ARE THE ONE that stated compression was lower on a turbo'd engine than a naturally aspirated engine not ME. I post 2 contradictory facts they aren't different and you start complaining. Camshaft & timing I'm fairly positive won't have squat to do with compression ratio but I need to do so research to be positive.

It's been unusually cold for Mississippi these past 2 weeks. Had a tree rat hired on the cheap to cut down a huge pine tree that was hit by lightning. We needed my tractor to remove the logs and debree ect... It was 15 degrees out and my old 1974 ford was froze up. As long as I pushed in the clutch and used almost a can of ether, we got her started. But I couldn't release the clutch without her going dead. I tied the clutch down and let her run for a few hours... she eventually unfroze and was ready for work... She just had some moisture in her.

My Kubota L3540 starts just like my car or truck, so easy, although it does have a Battery Tender and a freeze plug block heater I seldom use the block heater. It is in un-heated barn but out of the wind, I cycle the glow plugs once and bam it starts right up. I keep up to date with all maintenance , and before the cold winter months oil & filter is changed. I also add Power Service or Howe's to all diesel I buy in 5 gallon cans. I have owned 2 other Kubota's and all have started like this Grand L. Hope this helps your answer.

the dairy farm i used to work at had 2 jd's that where a pain to start in the cold, the 2 cases where a little better, but the masseys came to life easy.he's slowly switching to masseys for his feed tractors.

Newish JD 3038e turbo diesel... Shed kept, about 8 degrees last week, gave the glow plugs a few seconds and it started immediately and performed as it always does.

Last tractor was a 1974 JD 2030 diesel. Shed kept, but equipped with dual batteries and a cheap plug-in heater on a coolant hose. When needed in extreme cold, I gave the heater an hour or two, and it never failed to start. Poured out some black smoke, but started fine. Never used the ether injection port also provided.
