The most likely cause of the extreme heat is either slippage of the belt or the PTO clutch. Are you noticing the blades slowing down when in deep grass, when you engage the PTO do the blades go to full speed immediately or do they slowly pick up speed.
Other causes would be a bad bearing on one of the blade spindles causing extreme loading of the clutch.
engine burning oil
And engine knock is normally caused but I worn crankshaft bearing or rod bearing.
chemical (burning of the gas) to mechanical( the cylinder pressure turning the crankshaft).
They burn it in cylinders of internal combustion engine. Heat from burning pushes pistons, causing crankshaft to rotate. Rotation of crankshaft turns wheels.
crankshaft sensoryes because if the ecm isn't getting a signal from the sensor it doesn't know at what orientation the crankshaft is and won't let the ignition system start the engine. that's how i understand it to work
chemical (burning of the gas) to mechanical( the cylinder pressure turning the crankshaft).
The engine is burning oil.
Combustion is the chemical reaction that causes a car engine to work. It is produced by fuel combining with oxygen which causes pressure and heat to turn the crankshaft of the engine. This essentially gets all of the parts of the engine moving.
Blue smoke is burning oil.
Pistons converter the pressure of the burning air/fuel charge in the cylinder into torque through the connection to the crankshaft.
If the crankshaft sensor is dead the engine will not start
The length of the crankshaft throw is the stroke of the engine.
