Hydraulic thumb plumbing is split between bucket and thumb, tapped into bucket curl cylinder. It is activated using an electric solenoid valve. Much easier than running 2 additional hydraulic lines all the way back to the backhoe's main hydraulic control valve, though the thumb and bucket do not operate as smoothly or independently as on an excavator.

Factory thumb motion while curling bucket after adding BXpanded Quick Attach. Thumb fingers did not touch edge of bucket in stock Kubota configuration prior to QA installation.
