Understanding the Diverter Valve and Activating Hammer Mode

What happens here

Don, the product manager, explains the function of the diverter valve located on the excavator arm. This valve allows the operator to switch hydraulic flow between different auxiliary attachments. He points out that an arrow on the valve indicates which attachment is active: pointing one way for the flail mower (mulcher) and the other way for the thumb (grapple). He then demonstrates how to activate the "hammer mode" on the Kubota's digital display inside the cab. Activating this mode diverts the return hydraulic flow directly back to the tank, reducing back pressure and allowing the mulcher to spin up faster and more easily.

Goal: Configure the excavator's hydraulic system for mulcher operation.
