Thought I'd post this for kicks.
Boss has a JD L120. Tells me the other day that he thinks he might have thrown a rod and will bring it with him the next morning.
I look at it for him. Add 1.5 qt. missing oil. Spin it over, it's got fire but no compression. Know that the crank is spinning, so I run my videoscope in the plug holes and see that the valves are opening, but the pistons aren't moving. Let him know and wait a few days for him to decide what to do.
Today, he says go in the motor and tell him if it's worth trying to fix. So I hook the hoist to the front axle, disconnect a few things and 5 mins latter, the engine is out. 5 minutes after that have the bottom plate off the motor and boy what a mess.
Rods, crank, broken piston skirts, scared linners, etc.
