Cecil,

 It was probably a JD 60, the successor to the A.  The case on top of the engine is the governor and live hydraulic pump.  The Cam shaft is below the governor case and is inside the main case slightly above the crankshaft.  Not sure what happened but it sure didn't sound very good.

I had a 2cyl John Deere years ago that looked a lot like that 430V.  It had the 2 cyl engine with the pistons running the length of the tractor.  It was about the size of an A, but it had a number and electric start and rear lift.  It was stuck from sitting in Louisiana for several years.  I thought I had a little movement in the flywheel, co I filled the cylinders with Marvel mystery oil and alcohol and let it sit for a day.  Next day, we decided to pull it to break it loose.  The case on top of the engine that held the camshaft came apart after the second time I engaged the clutch.  I don't know whether the valves were froze or where, but it ended up for scrap.

  I also bought a 59 IHC R-190 old Air Force truck at a state surplus sale.  I opened the hood and turned the engine with the fan.  A week later I picked up the truck, and tried to crank the engine the next day.  We pulled it for over 20 minutes and tore out  the clutch trying to get it to turn over.   Either someone switched trucks on me or the engine froze in a week.

I would pull the head.  The head gasket is the most expensive part thanks to the Asbestos regulations.

Just my $0.02 and experience.
