A classic example of (what appears to be) a cast iron flywheel with no scatter blanket/shield, zero tie bars to keep the chassis in one piece, and a failure of the driver to notice the injection pump had stuck a plunger near the end of the run (that's the miss-fire in the engine) which sees to it a normal shut-down of the throttle may not happen. He'd have been wise to stand on the brakes and kill the engine, but hind sight is always 20-20.

The primary reason that the cast flywheel exploded is the ABUSE that the driver gave it trying to start in a faster gear than the tractor would handle.  If the RPMs are held down under 4000 and the clutch is used in the proper manner and not slipped excessively as was demonstrated at the beginning a cast flywheel can live, although it is not recommended to use a cast flywheel in high HP applications. Many of the muscle cars of the later 60s would easily run over 5000 and all of them left the factory with cast flywheels.  The NHRA became the leader in safety requiring approved steel flywheels.
If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
