The maximum oil flow settings of both circuits are conveniently adjustable from the digital panel. No additional tools or complex manual adjusting procedures are necessary. You can even program up to five oil flow rates corresponding to specific attachments into memory on the digital panel.
Controlled by the right-hand joystick, AUX1 supplies 19.8 gpm to operate attachments requiring hydraulic flow, like a breaker, thumb, or tilt bucket. With AUX2 installed the left-hand joystick supplies 19.8 gpm to operate attachments like a breaker, auger or tilt bucket. The right-hand joystick supplies 9.8 gpm to operate the hydraulic thumb. 
Kubota's improved 3-pump load sensing hydraulic system ensures smoother operation, regardless of load size. It allows hydraulic oil to flow according to the specific range of the operator's lever motion. The result is greater fuel economy and smoother travelling.
