At what temperature do you plug in your block heater?

[GreensvilleJay]

ALL batteries lose a serious amount of power when cold, and you NEED that power to spin the engine. While a warm engine spins over easier, it ain't goin to go round and round , when the batteries weak.
The other problem is a cold battery doesn't like to be recharged at a fast rate.

Never used one.
2017 BX starts every time. If it's real cold I will cycle the glow plugs a couple times.

battery tender on the battery.... thats it.


Never plugged in my powerstroke diesel either.

I think block heaters are generally unnecessary. (Unless you live in Alaska or Siberia)

If your battery is strong and the Glow plugs work properly.

It is not just about getting the engine started, warming is better for the battery, starter and all of the moving parts inside the engine.

Minnesota and Wisconsin get hit with an Arctic blast, so there's that...

The northern areas may not get above -10°F for three months, where I'm at in Central Wisconsin 0°F isn't uncommon, -10°F is occasional, and metal at those temperatures undergoes a lot of expansion to get to operating temperature, so plugging in likely does some good.

I use a temperature sensing battery maintainer, and bought a block heater and hearing pads for the engine oil and transmission though with the well replacement didn't have time to install them yet. I have a remote-controlled outlet though never thought of using an indicator light--excellent idea @PHPaul, thank you!!

Huh? What did you say?

I am sorry I could not help myself. I know what you meant. Happy Turkey Day!

Minnesota falls under the Alaska umbrella....

I rarely use the block heater. The first year, I put it on a timer when it got to our colder temperatures. I didn't seem to use it in those conditions though.

When it's really cold (10 or less), I don't use tractor to plow because we don't usually get much snow in those conditions and my Polaris Ranger has a cab and plow on it. When it's warmer(20s and 30s), my L2501 starts easily with just the glow plugs.

If I was going to use it in colder temperatures a lot, I'd put it on a timer. It does help the tractor warm up faster which probably is better for the engine/hydraulics.

If it is sunny very much, my shed warms up everything in the shed including the tractor every day.

I ordered some battery insulation "blankets" from Amazon yesterday. I plan on wrapping the batteries in the F-250 and both tractors so I made sure to order enough material to do that.

I'm a fan of block heaters and use them regularly throughout the winter, and that's for both tractors and the F-250. Like some others, I have a 50A water heater timer that I use to control an outlet and anything plugged into the outlet. When the old barn was still standing and the BX lived in it, I used to have a light that was plugged into the timer outlet so that I could see that the block heater was on. The barn was 75 yards from the house and I could see the light from the kitchen window. I did that for five winters with the BX and a winter with the MX6000HST. I would have the outlet turn on at 6am and 5pm for one hour in preparation for needing the tractor to move snow. Worked well for me.

Once I get the pole barns built I'll be doing something similar again.
