The engine heater offers constant heat to your vehicle and is super supportive for those cold weather mornings.

Optimal Visibility With The Best Tractor Wiper Motor Kit (Top 5 Picks)

Types of engine block heaters

An engine heater is one of the best things you can get if you want to save your engine from tears!

However, starting your tractor on cold can be a hazard for the engine life during the winter seasons.

For this reason, let’s check out your options and browse through the different types of engine heaters.

1. In-line coolant heater

The in-line coolant heater is very popular nowadays.

The coolant system works by maintaining a constant temperature; this allows all the fluid, such as engine oil, to stay intact.

Plus, thanks to the coolant heater pump, fluid circulates continuously, which results in constant temperature.

2. Freeze plug heater

The freeze plug heater is a small yet efficient device that helps deliver heat to the engine.

It prevents colder starting in the wintertime and protects your engine from further damage.

However, even though they are effective, frost plug heaters can sometimes be challenging to install.

Freeze plugs are probably not the best choice if you plan on transferring them from a tractor to a tractor.

3. Bolt-on heaters

Bolt-on heaters are probably the best ones if you want to warm the whole engine!

They do not focus solely on heating an engine coolant but instead warming up the entire system.

4. Dipstick heater

A dipstick heater replaces the oil dipstick with the electric heating element. With that, the end of the heater is brought back to the engine oil.

However, dipstick engine heaters are not the safest option to use.

Although they are quite cheap and easy to install, many fire incidents trace back to using dipstick heaters.

5. Magnetic block heaters

A magnetic block heater is probably the most common type of tractor heater.

Most of them will come with a strong magnet taped on the surface, which you, later on, attach to the engine.

They are used to heat and warm oil as they are stuck to the bottom of the oil pan.

However, you need to be careful with them. It’s recommended that you always remove the magnet block heaters before starting the engine.

After all, you don’t want it to fall off during the ride, do you?

6. Silicone pad heaters

Pad heaters work similarly as the magnet block heaters do. They stick to the engine and heat the engine oil.

However, unlike magnet heaters, these glue right on the engine, allowing you to plug them in whenever there is a need for them.

How to pick the right size of the heater?

block heater for a tractor

As you can see, heaters come in different sizes and voltages!

So, how exactly can you pick the right size for your engine? Well, it depends on a few factors.

One of them is the size of your engine, and how often do you use a heater for it? Are temperatures usually low in your area, or is it only for a season?

Another factor you want to consider is whether you use synthetic oil or conventional.

These factors can determine the convenient size of your heater.

Also, take a look at the HP of your tractor. Many tractors around 40HP will require a bigger heater for their engine.

In this case, you can use the 600W coolant heater as it will work the best!

Diesel vs. Gasoline

Lastly, consider the type of fuel you are using for the tractor.

A fuel type can often indicate what kind of heater will work the best for the engine. For instance, if you own a diesel, block heaters work wonders!

However, as you know, diesel has a high temperature, so it can get challenging to start it in colder weather.

Also, it’s good to know that a block heater saves fuel and can help the environment


Do you need a block heater for a tractor?

If you want to kick off the winter season right, you will need a block heater for your tractor.

It allows the tractor engine to warm up quickly, and it does not wear off the battery that much.

A block heater also warms up the oil, circulating better and preventing wear and tear.

Plus, it can help you minimize or eliminate carbon dioxide, which protects the engine!

When should you use a block heater on a diesel tractor?

A block heater will usually be required when the temperature drops to 15 degrees Celsius.

However, if you own a diesel engine, it’s best to start the block heater before the temperature drops that low.

How long does it take for a block heater to warm up a tractor?

In most cases, it’s preferable if you turn the block heater for at least two to three hours before starting the tractor.

However, if the temperature drops highly, you can even turn it on for longer.

Can you leave block heater plugged in while running?

Yes, you can leave the block heater plugged in while the engine is running.

However, most experts agree that the maximum time for leaving the block heater on is around 4 hours, so try not to go over that limit.

Other than that, it won’t hurt if your tractor is running with the block heater on.

What can I use if I don’t have a block heater?

block heater for small tractor

If you don’t have a block heater, you can always try using the alternative, which is the oil pans heaters.

An oil pan heater can be attached to the engine’s oil pan using magnets.

However, since they are attached via magnet, they can easily fall right off when you hit a bump in the road.

Another option is getting the lower radiator hose heater units.

Radiator hose heaters work by beginning the warming-up process in the coolant of the heater hose.

Most of them will have a higher wattage, making them easier to use and quickly warm up the engine.

Can you plug two block heaters into outlet?

Yes, you can plug two-block heaters into an outlet. However, it all depends on the block heater’s wattage ratings.

Final words

Tractors are necessary for farming, especially for farmers with bigger properties.

For this reason, you cannot afford to miss a day in the field just because the weather is bad and your tractor won’t start.

So here is where tractor block heaters come in and save the day!

They are convenient, affordable but not always reliable, so we took the time to review the top 7 models that work the best!

You can expect they will give their 101% in warming up your engine before your busy day.

As there were seven terrific models, I do have to admit it was not an easy job picking the best one.

Finally, however, the results are in, and it seems as though the Zerostart 3400017 Portable Electric Heat Magnetic Heater is the final winner!

It’s affordable, small, portable, and magnetic, so it easily sticks on the engine coolant!

Take a look yourself and see why this is one of the best block heaters for tractors!
