G John Deere HELP

[WD 45 needs help]

I have a G that has been sitting in a shed and the motor is stuck. How is the best way to free up this motor ? The motor ran great when parked in the shed.

Quart of ATF in each spark plug hole. and finish filling with diesel. Let sit for a day and put in high gear and rock the wheels. May have to do more than one time. Let us know how things come out.
Change oil after it comes loose and turn it over with plugs out to get all the fluid out of the cylinders.

Check that one of the cylinders isn't sitting full of gas. I've seen that happen if the float malfunctions.

First remove the valve cover and then the rocker arm to make sure there is not a valve stuck.then add automatic trans fluid.Buy or make an adapter that will go in the spark plug hole that a air hose will hook to and shoot air in the cylinder it don' break loose it will blow the atf around the piston,if it don't break loose let set and repeat for a few days

Be careful of rocking it or using bars to try and pry it over. I just got done putting one back together the guy had tried all that to get it loose. He flat spotted the rod bearing caps. Save yourself troubles and pull the head and block. You can more than likely knock the pistons loose with a block and hammer without damaging anything.

I filled the cylinders on my B with atf and let it set, every day I went out there and had a beer and gave the fly wheel a few tugs. about three weeks into it it moved.
