Intake Heater

Yep used in the marine field also. Physically creates a flame in the intake manifold which then gets sucked into each cylinder as you crank. Common on Perkins engines, later models used these in conjunction with glow plugs.

Theres more than a few laying in some DURAMAX guys toolboxes collecting dust. I know mine is taking up space in my top drawer of one of my boxes.
 
Not the greatest. For the DURAMAX LB7 they used them for the first 3 minutes of engine run time in COLD climates to prevent wet stacking. The 7.3L POWERSTROKE also used one for the same reason. The problem with most of them is they just aren't big enough to do a whole lot. The screw in heaters draw about 40-45 amps. Compare that to a true intake heater grid like the CUMMINS uses that draws over 75 amps per grid(and they used 2 on most of them) you can see the difference in effectiveness.
 
Are you sure those are the same as these? These burn diesel to put out heat

IIRC, some of the Gov't diesel generators use something like this to help with the start cycle.

If the goal is to replace glow plugs, the tractor intake heater seems undersized and a likely restriction during WOT.

If the goal is to make the warm-up period a little less harsh on the engine, my vote is to get a switch and manually engage the glow plugs for brief periods.
 
If it is the one that burns diesel, then that is the same one that CUMMINS uses. They work OK, but still not great. My grandfathers motorhome has one in his 8.3L, and if it's below freezing out, it will white out the area behind him for the first 30 seconds of run time. Turn the block heater on and it will fire up at -20 without much fuss.
 
They usually work fine and get the job done as far as I am concerned especially when you cannot plug in. ;) The thick smoke that billows out of the intake filter before you actually crank raises a few eyebrows though. :D More than once I have been on a boat in the cold months and the owner asks if i am going to use ether as all prior mechanics have and I reply no as I do not use nor carry the stuff. Moments later the engine is running, sometimes the owner marvels and responds that they wondered what that heat button does!
