  • Magnetic oil/block heater
  • Any of you used a Magnetic oil/block heater? I usually use a soft plug or lower radiator hose heater but it would be a big song and dance to install one on my Ford 4500 backhoe !
    I hate using starter fluid on any diesel. this backhoe is so,so cold blooded that I have to do something.
    I can also use this heater on my other 6 tractors if need be.
    Thanks,dave

  • I don't remember what year your tractor is Dave.
    Up till about mid 68 they had screw in frost plugs so you'd need to use an inline coolant heater. After 68 or so they used a typical press in soft plug.
    If you have the newer style I suggest you install a block heater.
    I have two of those 3 cyl diesels that I put block heaters in and they work great.
    A couple of hours on the heater and they will start like it's July. There is a frost plug just in front of the starter. A bit hard to get in there to install the heater but it can be done without pulling anything off the engine.

  • I got 2 of the Kats 200 watt heaters and use them for lots of things, including warming up the oil pan on the 8N and the big generator. They seem to work well. They work even better when you wrap moving blankets around the tractor to keep the heat in.

  • Maybe better than nothing, but I wouldnt trade ten of them for one block hose heater.

  • Hi Dave,

    It all depends on how cold it gets where you are and how big the sump is on your tractor. Maybe if kept in a shed OK down to zero. If you get hard cold of -20 or lower the oil pan heater will do little except help the engine turn over easier.

    A tank heater will circulate water throughout block and head warming the combustion chambers which is what is needed especially in diesel engines. It will also help reduce the amount of of oil dilution especially if you are using a winter mix of 80/20 or 50/50 diesel. For really deep cold use a tank heater and a small crib heating pad on low over the batteries and the machine will start at forty below like it's summer.

  • #1, Big Blue is the same way. It will not start in real cold weather. It has a fuel heater but it don't work for poo.
    I tried a dip stick heater. It worked but scorched the oil
    The best way is the block heater.

  • Look at the oil pan. Make sure there's a flat spot the right size. If the oil pan is stamped steel, you risk some cooking of the oil right next to the heater. The N-tractors have a cast iron oil pan with ribs on the bottom. I've been sticking my magnetic heater on the flat side of the pan, as close to the bottom as I can get. A cast iron oil pan is enough of a heat sink the heater is not going to burn the oil, even if left on for several hours.

    This is central Virginia. We get some single digit overnight temps and an occasional dip below zero is not unheard of. Most of the time I stay in the shop near the wood stove and wait for it to warm up a bit before venturing out. If I need a tractor to plow snow or haul wood, I go out and put the magnetic heater on it for 30-60 minutes. The tractor certainly seems to crank faster with a little heat in the oil.

  • The drawback being that your oil does a slow burn at the bottom of the pan, Coolant heaters stress the glycol. A block heater for the oil pan works for the engine and another one for the hyd sump also, No?
