I have read a ton of posts regarding stuck/frozen motors and hope mine is not as far gone. See "M radiator gurgling" post to reference my issue of a couple weeks ago. I have been working on getting the right 50-50 mixture into the radiator. Presently I have about 2 1/2 gallons of a-fze in. I moved snow last week and no problems with overflow, temp or gurgling. I tried to start the old M today and it's froze/stuck. My plan is to plug in the block/tank heater for a whole day and see if that does the trick. Couldn't budge with hand crank either. Minimal ice visible upon radiator inspection(fluid is dark green) but know something could be frozen solid below because of the water that was in there. Any suggestions or comments.

First thing I would try is to push the clutch in and then see if motor turns over. The old farmalls were noted for getting water in the transmission and rear end and freeze up in the winter. If it turns over with the clutch pedal down would bet this is the problem or could be stuck between two gears.

Here's what I learned today and we'll go from there. I can grab the fan and move the bottom pulley about an inch.(Probably a good sign) 2nd- The only gears I can get in is R and 4th.(Probably stuck between 2 gears???) I remember a long time ago dad pulling the gear shift and aligning the gears with a crow bar when it was stuck. What have I learned and what do I need to do next. I resisted temptation and stepping on the starter to avoid breaking something. Let me know...Thanks for everything so far.

If stored outside, you may have gotten H2O down the stack and frozen your valve train. Try dry gas or isopropyl down exhaust manifold and give it a couple hours to work.

What about the possible of water in gear boxes or hyd. pump area. If froze might not turn, just a thought. good luck

If you used a 50/50 mix of antifreeze it should have circulated throughout the engine, if any water was left in the engine it should've mixed in with the antifreeze mixture.

Did you mix the 50/50 antifreeze and water together before adding to radiator? Hal
PS: I agree with the other postings on checking your for coolant above your pistons or a jammed starter.

Someone can correct me if I'm wrong, but coolant doesn't make a difference to how hard the engine is to crank. Even if your coolant is frozen, your engine should crank over. I'd look at the starter assembly to see if anything is jammed. You might also want to check the oil in the crankcase. If it's too cold and viscous (thick, flows slowly), it will make the engine too hard to turn.

My two cents(Canadian). ;-)

P.S. Most tractors that are termed "frozen" or "stuck" are locked up due to rust. I've never heard of a tractor locking up due to cold (except for oil being too cold).

Many things to check here. First, make sure that the starter drive isn’t jammed into the flywheel by loosening it and rocking the tractor back and forth in high gear. If the engine rolls with the starter loose, then just tighten it up and go.

There is an outside possibility that when you shut it off, it got into two gears which would make it act like it was locked up unless the clutch was pressed in. If the engine won’t roll with the clutch in, then you need to look further at the engine.

Tug on the fan blade and see if the belt will slip a bit or if that will turn the engine a bit. If the fan won’t turn, then that might be frozen and prohibiting the engine from turning, but I doubt it.

If after checking the starter, fan, and pressing in on the clutch the engine still won’t turn, then remove the spark plugs and check to see if there is water in one of the cylinders. I hope you don’t find any…that means a bad head gasket at the least and a cracked head at the worst.

Good luck…

I agree with the other guy as far as pulling the plugs. If you find water/antifreeze in any of them your looking at a bad head gasket and or a cracked head/block. If you do find water/antifreeze in any of the cylinders turn the engine over enough to clear the cylinder and then pour some tranny fluid in each cylinder to keep it from locking up the engine. Then I would open it up to see what maybe wrong. Also if you can't turn it over with the plugs out blow out the cylinders and then put tranny fluid in. Hopefully you don't have a piece of ice in one of the cylinders, because if you do you may have a cracked sleeve.

Hopefully coolant did'nt find a way in one of your cylinders from blown headgasket,etc. This creates a condition called hydrostatic lock meaning the liquid that gets in the cylinder affected won't compress and making you think the engine is seized up.Pull ALL the spark plugs out and try to crank-er over and see if antifreeze blows out of one of the holes??

Sarter drive jammed???
If the water is frozen in the block the tank heater probably won't help because the water can't circulate. Check oil drain plug for frozen water in crankcase
