Mower engine won't turn over.........

I have an older John Deere riding lawn mower. The deck broke and I parked it on the side of my garage covered with a tarp. It's been outside covered for about 1 1/2 years. The moter ran fine when I parked it, now I can't get it to turn over. I don't know if the motor seized up or the recoil is stuck. How can I tell if the motor is seized or not, any tips?

You will need to provide more info on the rider. For now we know you have an older mower, most likely green, with a yellow or black deck that broke, and a motor.
Is the deck still on it?
You mention recoil? Is it electric start? Battery charged?
For the engine itself, you can use the pulley on underneath the engine that the deck belt goes around. Grab the pulley and try to turn it. Slowly work it back and forth if it is not free at first. Does not need to be far or fast just enough to tell if its free or not.

It's not a electric start, and the deck is still on. I can put the transmission in nutural but the recoil rope will not pull the engine over. Seeing it's a manual 5 speed, I put it in gear and tried rocking it back and forth with the spark plug out. Tires seem locked up, thats why I thought the motor was froze up from sitting. Can I spray penitration oil in the cylinder and let it sit for a while?

I had this problem with a white lawn tractor and it was the belt going to the mower deck, the belt rusted into the pully. If teh engine sat for that long its a good idea to put oil in the cylinder anyways but I doubt thats the problem. Try to get to the flywheel and see if its rusted to the coil. Its amazing on these little engine with a little rust somewhere you think the engine is seized up. I would take the deck off of it and Im sure with a little muscle the engine will turn over.

One more thing, dont go gung ho on the pull rope, you dont need to mess that up, once the engin turns by hand then use it.

You'll need to isolate the source, whether it be the engine, deck or drive train. The first thing I would do is remove the flywheel shroud and check for rust between the ignition coil and the flywheel. Next, if that's not the trouble, I'd remove the deck and tranny belts from the engine pulley and then see if the engine will turn over. If it will then it's either the deck or tranny that is "frozen" with the tranny the most likely suspect.
