I put a 200 watt magnetic oil pan heater and a battery charger on my L1501,-20celcius it will start no problem. After 4-5 hours being plugged in.

4 cyl would need a bigger pan heater and a good strong battey if machine is in decent running order. Or a block heater for sure.

Post your tractor info, perhaps someone will chime in with block heater part number and where it goes..

Well when did you buy the fuel that is in your tractor that you are trying to start NOW..... in the warmer weather?

If that is the case, your fuel has gelled which means some of it has turned to wax and your engine cannot process it.

You need to get the tractor and its fuel tank warm for many hours so the wax turns back to fuel and hopefully the engine will start. Once it has started and run for a bit, drain the tank and filters and replaced with fuel you buy at a truck stop, which is pumping lots of fuel, so it will be a grade for colder temperatures. Do this before you put your tractor back somewhere cold as the fuel can turn to wax while the engine is running!.

The truck stop will also be selling various fuel additives to help with fuel gelling. Ask them for the most popular one which deals with both gelling and moisture and add the proper amount to the can of fuel you are taking home. Put the new fuel and additive in the tractor and drive it around to burn off any of the old fuel and get the fresh stuff with the additive throughout the many parts of the fuel and injection system.

I too live in a cold part of Canada and some of my friends who are not almost daily users of their Kubota's have done just what I am asking you if you have done.

They buy a full tank of fuel in late August or early September, do some work with the tractor and then let it sit until they need to move snow in December or January. Now they call me to come and help them because their tractor wont start. I work outside and freeze my fingers off for hours trying to undo what they created by not planning ahead knowing what a diesel engine requires in the way of TLC.

For some owners, they get their tractor dragged into a heated garage or shop. Others have built a tarp tent over their tractor and put lots of heat inside. The tractor and all its metal parts has to feel warm to the touch in the coldest part of the tent or shop to be at a warm enough temperature for the fuel turning to wax process to reverse itself and this takes time measured in hours not minutes. Usually it is best, once the tractor and fuel are warm and before you try and start it, is to go through the bleeding process to ensure there are no air pockets created during the gelling and attempts to start.

If doing the heated tent thing, don't do it in a way which can start a fire which destroys your tractor and home. If you can, the heated shop is the safest and best option.

If my hunch is completely wrong, then, as other forum members have said, provide us with some make and model details, tell us how you operate your glow plugs, and what smoke if any is coming out the stack as you try and start the engine.

Looking forward to your reply! In your profile provide a more detailed address as another Canadian may be closer than you think and could drop by to help.

Is your tractor located where there is electrical power?

You can use all the aids mentioned, or even a heat gun on the intake manifold, but you need a good, charged battery, good fuel, and an engine with good compression, and a clean air filter.

For anyone to really help you, as 85Hokie mentioned, you're going to have to give us more clues!!
