Magnetic Heater Volt 110, Watt 300 for Industrial Tractors 3009-1001

I bought this to use on a 1960's gas bucket tractor that I plow with. The heater does work fine but the heat actually making it through the casting and into the fluids and internals of an engine is minimal. If you live in a place where around 0°f is common I'd spend the money and time to put an inline coolant heater or an element in the block.

This heater warmed up my Diesel truck's Oil enough to make it crank with ease in 10 minutes during 11 deg weather. I haven't needed it on my tractor at this point, but as soon as I do, I'll re-post it.

As others had stated does not raise temperature very much

I guess I can’t expect much. It’s only 300w I believe so that’s not much to heat up an oil pan. But it seems to work as advertised otherwiseUpdate - 14 months later. I have only used it about 25 days maximum and it's no good. Won't heat anymore. It's beyond the return date, despite only a few weeks use. Seems to be a crap shoot on quality. $100 gone

This heater only lasted for one week and then overheated and totally quit working. Will not order from this company again.

I left this on my tractor oil pan and didn't turn on the tractor for days. I came out to turn on the tractor and found the device melted. This is completely unacceptable.

I liked the ease of use, I used it to help with cold start, it works great.

The media could not be loaded.  This is the third one that we have got all three have broke or melted within 4 months of being used. Amazon allowed me to return the 2nd one But they will no longer allow me to return the replacement that also melted! I Do not recommend this brand… Sometimes the temperature will be fine and then overnight it will get very hot and the thing just falls apart
