Block heater for Super 77-where does it go?

I am perplexed as to where I can fit a block heater for my super 77. There is no room for a lower radiator hose heater given the clearance issue with the generator belt. The block drain plug is such a small diameter that nothing will fit there either. There isn't any real room in the two radiator hoses to splice in to fit a recirculating type heater. What does everyone do to effectively heat their tractors in the winter? I am in northern minnesota and this is a definite necessity. Help!

My dad owns a dealership and have put them on tractors before. We put a pipe in the drain plug at the rear of the block and another where the drain is in the lower radiator cast elbow is. The block heater would go between the two spots. The block heater goes between the two. Be sure the heater is in the correct direction so the water goes in the right direction. There is a ball that lets the water go one direction. If you are planning on leaving it plugged in all the time, use a 1000W instead of the 1500W. We have run into problems with the heater making the water too hot an creating problems with the thermostat and water evaporation.

Hi Bob , I don't use any type of heater. My tractors are gas. But it seams like I have seen heaters that go into the dip stick hole.

Don't use those dipstick heaters. The only way they add enough heat to matter is to cook the oil. Not good. Go for a magnetic one then - they are too wimpy to help us much in MN, but at least they don't hurt anything.

The engine heater for these tractors fits in the lower hose. You need the cast elbow that was desighned for the heater which has a hole in the bottom which the heater screws into

I have my 1500 watt plumbed into the tractor via a couple of pipe fittings on the starboard side. I'll look at home and rely the info tonite or tomorrow morning

I forgot to look last night. It is similar to what Dean has been describing. I use two tappped holes already on the tractor, one in the front and one in the back on the starboard side. I believe that the input to the L-shaped heater is on the bottom. This draws from the front of the block. The output is on the top. This goes to the back of the block. I am also in MN so I know the feeling....Jim

Thanks Jim. I know the tappable holes you are referring to. One holds the drain petcock at the rear and the other is just a plug stuck in a similar hole at the block's front. This sounds like the best route to go. Finding one of the cast elbows for the lower radiator hose is tough and they aren't cheap.

There are block heaters that are magnetic, and "stick" onto the side of the block. I would imagine the efficiency isn't as good as the recirculating type, but would be better than nothing. Especially if you could make a blanket to go over the engine to keep the heat in.

Thanks. I already have a magnetic heater on the oil pan, but I would like a traditional block heater as I think they do a better job of heating the entire engine. Any other ideas?

Bob, I live in extreme northern Wisconsin so I understand your urgency!

I'm not familiar with the 77 but on my 1650 there is a 1/2" drain plug at the bottom of the lower radiator hose housing. It's hard to see and even harder to access but block heater - AGCO 30-3141748 & block heater cable - AGCO 30-3141756 fit and work perfectly.

Another alternative is to measure the size of any of the freeze plugs on the side of the block and use an automotive type block heater to replace one of them.

BTW, the local hardware store sells a special block heater extension cord. It is a vivid blue color, made in Canada, and remains flexible to -25 and has a special female plug that allows you to get the male plug on the block heater into it very easily, even at -25. Actually, it probably works in even colder temperatures but -25 is about my limit for plowing snow!

Good luck!

Dean

Thanks for the info. What size (length wise) is your heater? My drain plugs are 5/8" diameter with one in the rear of the engine block and the other in a cast elbox in the lower radiator hose setup. This drain fitting in the elbow is on its side so there would not be much room for a long element. I haven't pulled the drain plug in the block to see how much room I have there. As for freeze plugs-there are none. I would be happy to take one out and put a plug heater in if I can.

I had the same thought before I bought the heater. But it's only maybe 2" long at most.
