Description:
Maintain smooth power transfer and consistent blade performance with the PULLEY BLADE (KU-K511271140)—a genuine Kubota drive component engineered for mower deck systems.
Specifically, this blade pulley plays a critical role in transferring belt-driven power from the deck system to the cutting blades. Moreover, its precision-machined design ensures correct belt alignment and tension, reducing slippage and wear. As a result, it helps maintain optimal blade speed, improves cutting efficiency, and extends the lifespan of belts and spindle components.
