A ground drive belt, on the other hand, is more expensive due to the engine’s increased performance and maintenance capacity. Furthermore, the belt material is pricey.

A primary mower belt is a deck drive type that pulls the mower forward while also assisting in the spinning of the blades.

The ground drive belt, on the other hand, is a heavy-duty type belt that can deliver energy through its chain. It guarantees that power from the transmission is reliably transferred to the rear wheels.

As a result, the ground drive belt outperforms the main mower belt. It not only performs well but also ensures that power is not lost.

5. Mower Application

The primary mower belt can be used to convey power in tractors by the users. A ground drive belt, on the other hand, can be used for riding.
