An ounce of prevention is worth more than a pound of cure especially at 20 below! A lot of you folks new to diesels find out, belatedly, that diesels are not like SI engines which burn gasoline especially when it comes to cold weather. The first sign of a cold weather-fuel related problem is a...

Usually condensation.It also indicates low usage. If you use you tractor for any length of time, the transmission oil will warm up and water will evaporate Damaged boots at the bottom of the shift lever(s) can let water in also.

It sounds like something is stuck in the injector pump/governor part of the controls.

I have owned a few tractors in my day so I'm familiar with service manuals for various manufacturers. Admittedly our M4500 is an older tractor( 1978) but my 1954 Ferguson TO-30 had better Owner and Service Manuals than the M4500 Kubota! I don't know if the newer models are any better but I am...

You're not working it hard. Unlike a spark ignition engine whose peak gas temperature remains nearly constant, a diesel doesn't hit it's peak gas temperature until it's at max power. So running around 10% max output at really cold temperatures isn't gonna' give you a fast warm up.

There is a short most likely between the battery and the starter solenoid . It could be the cable or the starter solenoid itself,(if you have that kind of starter) or in the magnetic switch if you have that kind of starter. if you hook it up directly, battery to starter, and the starter rolls...

All the numbers you've shown are casting numbers. there should be a flat spot on the block above the injector pump that will give the model number and the serial number stamped into the casting.

All these fixes seemed to be focused on elements that are downstream of the fuel tank. If there is a problem with production debris in the tank that it could be the tank strainer that's is partially clogged and has ice accreted on it. If you have condensate in the tank, it can freeze on the...

Re: Update: 3901: problem with cold start You're not the first person to have this happen. Any time the temperature gets below freezing, you can get "jelling" and /or icing of condensed water. To determine which., Use a blow drier on the filter and then open the filter...

The info I have seen on rear wheel width is to the center line of the tire. The width of the track is beyond that. You also should realize that on most tractors, the wheel spacing is adjustable. Also the tire width is a variable. So it's hard to give a definitive answer to this question. It's...

Thank you That's a good piece of information.

You really only need to have a cycling timer if you always want the tractor to start at a moments notice. A lot of dairy farmers and hog farmers need this because they have pto generators as back up power so they need the tractors so equipped to start right away in the event of a power failure...

Most of these block heater use 3-5 amps @ 120V so a 10 amp capability is more than adequate.

"Don't see any smoke to speak of when cranking." That makes me suspicious. If the injectors are fueling, you should see some white smoke. I wonder if you have some sort of drain back so the fuel lines upstream of the injectors are dry? Do you have a lift pump and if so, is it pressurizing the...

My experience with magnetic heaters is not good. It's hard to find a really flat surface big enough to get them placed properly. A block heater sized for your tractor from the manufacturer is your best bet. I just put one on our M4500 and it was easy to install with the supplied instructions...

Does it operate normally in the summer months or is it cool then also? If so it might be a failed open thermostat. It could also be a bad temperature sensor. In cooler weather it may take longer to come to temperature so if your using it with light loads and for short periods in may not warm up...

2 to 3 hrs.

The battery on our M4500 crapped out on us and it would not even heat the glow plugs, let alone turn over. The battery was 8 years old. I installed the new one this morning and I had the block heater plugged in and it started on the first turn.

Are you sure your block heater is working? They do fail. Battery heaters are also a good thing to have if you have really cold temperatures regularly, so you might want to consider that. Battery output drops and oil viscosity increases as temperature decreases so when you need more battery...

Sounds like restricted fuel delivery. What's the temperature where you're tractor is located? Are you using summer fuel? That can wax up at ~28°F in the filter or on the tank outlet strainer, etc .Ice from condensate can form on the tank outlet strainer or on the filter itself. If you can get...
