Magnet heaters, dipstick heaters, coolant water heaters. Exactly what part of the Tractor, parked outside in the wind are we trying to keep warm? WHAT PART OF THE TRACTOR IS MOST EFFECTED BY COLD WEATHER? What about a Battery Heater?

The combustion chamber ( head/piston) if too cold will absorb heat faster than heat is produced by air compression. A hot intake manifold will give compression heat a "running start". Oil has to be a winter weight synthetic or preheated mineral oil. As previously mentioned, oil the consistancy of cold corn syrup will not flow readily into the oil pump and out to bearings.

A good frost, tank, or radiator hose heater is the way to go. Heat the coolant, & it will warm up what needs warming.

For the most part warming the oil will start a gas tractor - but dipstick heaters are bad, fry the oil. Magnetic heaters don't put out enough heat to help you out in an hour or two...

For diesels, you want the oil heated, & you want the head heated.

If you pay attention to your electrical system it should be good down to 20-30 below.

If you get into the 40 below area, then warming the battery is not a bad idea. At that point the hyd oil should be synthetic or be warmed as well.

Depends on who is going to be starting it. If it is a diesel, of course the coolant needs a heater, but if it is going to be run by someone who thinks he has to rev it up right away, then the oil should be warm too. A couple of years ago I did a little work on a neighbor's old GMC truck with a toro-flo V6 diesel. This was in the winter with the temp probably somewhere in the teens and when one of his employees came and got it after I was done with it he floorboarded that cold engine and away he went with the frigid engine sputtering, popping and smoking for the first mile or so. When he got home with it he called me and said the engine was knocking. You guessed it, he spun a rod bearing. The oil pump just couldn't suck up that cold oil fast enough.

Sounds like that driver needs his butt kicked HARD!

When my wife and I were first dating she had the same habit. Over time she has come to understand the importance of letting the rig idle and get the oil circulating. Got 2 boys growing fast and they will get a knock on the head if they pull this stupid stunt.

On my bi directioal ford 276 II the most important thing is the oil tank for the hydrostat,it has a block type heater.
I've a couple of magnetic heaters that I use on equipment that that is only started infrequently started in the winter.
Everything that is used daily has a tank or block heater.

If you have a gas engine, you probably never need a heater if you use synthetic oil such ad mobil one 5w 30, as long as your battery will spin the engine. Even old gas tractors like M and 350's will start without a problem, just choke it a little until it starts and gets warmed up. On a diesel it is always preferable to have it plugged in as it reduces the stress on the motor. High strength metal has a tendancy to get brittle when it is cold, as well as the risk of blowing out the head gasket or cracking the head if you use starting fluid.

We have several pieces of equipment (750 HP snowblowerw and loaders) and if we can't put in a heated area we have heaters on the oil pan,batteries, and block (for water) and most of the time they will start very well when it is 20 below and wind at 35 mph. You want to have a good 20 or 30 anp plug in . Jim

I agree with Jim the more heat in the winter is better for everything.

The head and cylinders being warm is going to make it want to start. Thus the coolant heater is the most common. Of course the best way is to have the whole tractor warm. I do whatever I have too when it gets real cold.

I am in the deep south and do not use heat at all. Some days though it can get pretty cold and take a lot of crankin to get her to start. I just sneak in the house and get her hair dryer, and blow the hot air into the intake, starts like summer, run low idle till it gets lubed.

Out of desperation I used a dipstick heater on a gas tractor for about 3 weeks 20 below weather. While it got me through that deep freeze I wouldn't recomend it. Haven't used it since. GW.
Water heater id most efficeint I'm thinking warming up the compustion chambers for improved vaporization. and the cylinder walls warmed up helps the oily piston rings slid over the cylinder walls. If it's exceptionaly cold putting a slow charge on the battery(s) will warm'em while improving their electrical energy.
Never trid a magnetic heater. Although warm oil would help a crank shaft turn easier. But, You can use a lighter multi-grade engine oil to help here.
Here's to making smoke.

I'd say coolant becuase if its kept warm every thing else in the engine will be warm and on some tractors that will even help the batter because it is under the hood close to the back of the block

The engine mainly although the battery will perform better if warmed to a sensible, say 20 degrees Celsius. The pour point temperature of all oils must be exceeded for them to be pumped easily and have proper lubricating properties. Transmission oils are often neglected, by the user, from the equation for safe operation, but normally things just warm up quickly enough for it not to be noticed.
