Same Mercury 75 Farmtrac 795DTC
What is everyone using for their cold weather starts? I have 1 magnetic heater but I'm thinking of getting a second one for my tractor this winter. It does have a glow plug (which I replaced 2 or 3 years ago) and it doesn't seem to work that great when its really cold out (10F or less). This is for my farmtrac 785dtc. I was looking for a block heater but can't seem to find any information out there for this engine.

My other option is to replace the fuel line to the glow plug as the plug in on the opposite side of the fuel filter and the line goes all the way around the engine. I was also thinking that maybe that line is clogged or has crud built up in it and could maybe clean it out somehow. Any suggestions?

My experience with magnetic heater says they are nearly useless.

Hopefully the SAME engine is liquid cooled and you will be able to find a good block heater for it.

Well I see it is liquid cooled so you should be able to find a block heater for it, maybe talk to a Deutz-Fahr dealer they probably will know exactly what you need.

Yeah, this one is liquid cooled. I was trying to find something simple for it but it'll have to wait until I get around to looking the tractor over again a bit more detailed to see where I can even put it.

Its in the 40's here on the south shore of the BIG lake. Breezy out of the north and so much so the lake boats are hugging the north shore.

Block heaters on everything and that’s it.

I have a warm shop, but also a block heater.

My Kubota has a lower hose tank heater. Works just like an old percolator coffee pot. I bought the Kubota brand new in 2009 and have not yet had to use this heater.

Not enough snow to plow and no reason to go out in the cold. However - it starts easily at -20F without any assistance. It just take forever to warm up.

Just need to measure a frost plug. Then, order up a block heater that fits it. Just remember to not over tighten the lockdown screw! They make a world of difference on cold weather starts!

Old school Thermal start. Drips Diesel on a Electric coil and burns inside the intake. Sucks in the hot air When you go to start it. Using the Decompression it warms the Cyl. up. I wait for the oil light to go out and release it. I only have to use it rarely in Ga. but it does work well when I do use it.

This is what my tractor currently has, I guess I refer to it wrongly as glow plug sometimes. I believe the fuel supply going to it is being obstructed because you should hear a puff after it is on for a few seconds. I replaced everything but the line a few years ago.

My older SAME has this as well and when I replaced that many years ago, it would fire right up, even below 0.

well if that is what you have when it is working it will start when it is real cold! Fix it. Battery blanket. make sure fuel doesn't gel. As long as it turns over fast enough when it is cold with that system and it has fuel it will start.

No reservoir either so to get fuel to the coil this is all I do. Suck fuel from the tank and then Squirt it back in after starting it. From another member and basically the same Tractor. Just a US. model. Serious heat and with a block heater in Sub zero Temps. no doubt it works

enough for anything else

I keep both my M's in an unheated and no electricity barn and the glo-plugs have always worked just fine. When it gets real cold out (and it does up here in Michigan), abput 15 seconds on the plugs equates to about half a turn on the engines and they fire right up and always have. Having said that, I'll let them idle while I have a coffee and then go out and use them.

Just because you use a block heater. that don't heat the hydraulic fluid whereas idling them does because the fluid is circulating in the pump. Do the same idle but only about a minute on shutdown, to let the turbocharger cool down as well.

I'll use the block heater to start mine and then let them idle about 1200 - 1500 for about 10 minutes. Enough time to get coffee, snack, and pee break! Then off to work.

More than enough time to warm engine...block heater.

Your 785 has 4 cylinders, Isn't there a glow plug for each one? Please excuse my ignorance, I know nothing about the 785dtc

I have Yanmar and Shibaura engines in my tractors, the guys who have them know what I'm talking about. When it's too cold for them to start without anything but glow plugs, I'm staying in.

I think Iseki are about the worst that I've owned for cold natured in the winter. But they are bullet proof once they are started.

It has the thermal plug on the intake. The diesel drips on it to create the flame to warm it for the start. You'll hear a puff when it's ready to start and we'll mine don't puff, even after I replaced everything but the line.

Freeze plug heater on the Rhino tractor and a Kats inline lower radiator hose one for the Ford 550

Both have intake Thermo starts as well.
