The crankshaft is the component of an internal combustion engine of agricultural machinery, or a tractor to be more precise, responsible for transforming the reciprocating action of the pistons into the rotating motion of the drive shaft. This rotation is a crucial component of the tractor’s engine since it turns the wheels, allowing the tractor to move ahead. The crankshaft is the central component of an internal combustion engine and is used to attach the various moving parts of the engine. The crankshaft is subjected to extreme bending and twisting forces. Forged steel or cast iron are the most common materials for crankshafts. Forged crankshafts are often more expensive than cast crankshafts due to their superior strength.
