Hi George, my LT40 has a gas engine. But I have always wondered if the diesels have a plug in heater to keep them warm. Probably not.

Glad you got a mill. I hate cold weather!  :)

Ive got the lombardini diesel and found it fine in cold/snow the only things i found to watch weremake sure you have antifreeze and you prime the diesel pump and that diesel isnt to much of a "slurry" from freezing.
Im unsure if the cat has a manual diesel primer?

Cheers

My experience with Cat's are from days gone by however, most if not all diesels like
heat, so if you can preheat the block with a heater of some type
and keep your fuel liquid you should be fine,

How cold does it get in your neck of the woods?

Keep the glows in good order and all your filters. If she's hard starting get the timing checked, my cat skidsteer is the best starting diesel I have ever seen, I dont even hit the glows till below 10 then only give them 10-20 sec. The kubota on the mill is a close second, but I do have to glow plug that on longer I blame that on the mechanical fuel pump though.

That 51hp cat is actually a perkins. I turn the key and let the glow plugs warm up a little and then hit the starter. The only problem I have had on these engines starting is they seem to be a little low speed on idle so you may have to turn the idle speed up a little. The other problems with these engines is another matter.
Two LT70s and to much other support equipment to mention.

 On any diesel if you can hold the throttle open when cranking it will start better.   Steve

Warmth always helps: heads, and oil, in that order.
Any way you can warm the coolant and oil will help 'er start. careful with the ether. I would not use it due to the risk of damage.

Thanks for all the input today. I will check several things tomorrow and talk to the cat dealer in town onMonday. It was 26 this morning but my Kubota tractor started fine. Many items here to look at and I will look at all plus clean the battery terminals. The battery shows good but will take to be checked Monday also. It started fine yesterday at 40 degrees.

It doesn't get that cold here but I have several diesel engines and anything below freezing will make some of theme hard to start I simply use a dipstick heater in the ones that don't have a built in block heater :::: problem solved on mine anyway
Have a great day unless you have other plans !!!

Clean the battery terminals, yes, and be sure that all your wiring involving the battery, ground, and starter is fully functional. Sometimes wires will break part way through, or develop a short, or whatever, and not be as efficient, but still marginally work.

Draining your fuel at the end of the day and bringing it warm fuel to start with may help-- even better, but more trouble, is draining the oil when you're done, and heating it up before putting it in before starting. Ditto coolant. Or any other way you can warm the engine up from the outside before trying to start it. My dad used to take a bucket of hot coles and put it under the bulldozer engine, with a tarp over it to help keep the heat in. That would warm things up enough to get its blood pumping.

These are all "old army tricks," or "old Russian tricks," or as we would say in Maine, "old indian tricks," though I'm not sure if the old indians had diesel engines. . . .  just sayin'

Valley, I'd actually never heard of a dipstick heater-- you learn something new every day. That sounds like a real spankin' good idea-- imagine if the old indians had just come up with that idea, way back when!

I have used a kerosene topedo style heater pointed at the engine for a while to get it going after my glow plugs bit the dust.

I used to carry a propane stove burner  and fire it up and slide it under the oilpan on my ol GMC . Then whenI got it running I would take it to the back and warm the air valve so the brakes would work

And then stick it on your dash board to act as a defroster?

Well, many good replies. I didn't know about the dipstick heater either.

I work for a chairlift company in the winter, and we have had generators to start when realy cold. Biguns, 400KVA or more.
Two tricks i've found, boil a big saucepan of water, and bring it up puting the fuel filter butt in it. Even better atach the saucepan with two bungees while you start it.  And put some boiling water on the intake manifold, slowly pouring, to raise the intake air temp. Well, there's always the MEK solution.
