Search amazon for kat block heaters... If you want to do it cheap, search craigs list for coleman single burner camp stove, that's what I use in barns without 'lectricity... Just shim it up, so's its about 4" under the oil pan, and you might have to use a couple sheets of plywood, and a tarp, if the barn is windy...

I got mine for $70ish from the dealer. Installs easily enough, once the freeze plug is out.

Mine came with a block heater, maybe it's a standard item in northern climates. Unfortunately I don't have hydro at my bush lot where the tractor is used

5-Star Manufacturing out of Tennessee makes (imports) the Kats Line of heaters.

Install the red T-shape heater in the lower radiator hose, coil up the wire where it doesn't get snagged, and you're good.

Plug it in on a timer overnight if you can plan ahead when you'll need it in the morning. Mine takes about 2- (no more than 3-) hours to bring it up to temp.

At 0-deg F after heating my glow plug lamp barely flickers and she starts right up every time with no smoke.

Ours are plugged in ahead of starting anytime the temp drops to 40-F and below. Overly cautious but easier on machine, battery, entire system.

Add also a Schumacher on-board automatic battery tender. Avoid Harbor Freight's similar model. Our charger is plugged in continuously from about now through March.

For the heater be sure to use the red Kats "T" type; O'Reilly's lists a silvery soft-ball size cross-reference model that is NOT equivalent in size or wattage heat output.

For the effort and ease, I perfer the lower radiator hose heaters compared to freeze-plug type. Personal preference and your choice. Kats makes both. My dealer sells Kats as their after-market add-on.

You can search this Forum and turn up many many strings on the same subject.

Please post back your continuing experiences so we may all learn.

I'm in the exact same boat. My L3901 starts perfectly fine in the cold, but I'd feel better with a block heater and they aren't terribly expensive (dealer told me $85 but I am seeing them cheaper online). I think I found the threaded plug with the 17mm hex in it that needs to come out but it seems like a pain in the butt to get to. I think I may let the dealer install this, maybe I'll get a rear remote valve installed as well. Anyone have pics of their installation of the block heater?

I'd vote for the block heater as it heats the engine block area most directly. Installed one on my Kubota and it's a simple job. As others said, it's very effective. The frost plug on my engine was very easy to get to. I don't know your machine but unless you just can't get to the plug I'd be hesitant to take it to the dealer since it's such an easy installation.

I think I found where it goes, the DPF filter and bracket is crowding the area

That looks to me like the water pump port for a heater option on a cab model. The block heater would be installed in a freeze plug on the block. The last 3901 I installed a block heater on had a knock-out style freeze plug, and was just in front of the starter.
