I rolled over my jinma tractor. It seems to be hydro locked. It doesn’t have glow plugs. It’s a direct intake. Anyone have any advice about getting it unlocked.
Also I’m getting to old to do this myself – any advise about finding a diesel mechanic I could hire to help me. here in Massachusetts.
Thanks

Not exactly sure what you are saying here.
You rolled your tractor, or you attempted to start it and the engine won’t turn over?
In any case, which engine are we talking about?
Have you checked the oil and radiator levels? Anything out of the ordinary there?
When was the engine last started? Did it function normally at that time?
If I had an engine that won’t turn over, after I proved the battery and starter, I would put a wrench on the crank and try to turn it both directions. Or open one of the bell housing ports and try to turn it both ways with a pry bar.
If you can’t turn it either way, there may be something else wrong.
If that didn’t yield any results, I would then take the rocker cover off and try to determine if there is something wrong there.
Typically a true hydo-lock means that the cylinder is full of fluid. Most piston rings are not an absolute seal, so they should let the fluid leak down past the rings into the crankcase after some time. Path of least resistance is to give it a day or two and try again.
