Need to add a new function to your Kubota Tractor? This Summit Hydraulics complete 3rd Function Kit allows you to add an electronically controlled hydraulic function, most commonly used to control a function on a:

  • Grapple (open/close)
  • Snowblower (chute, deflector, or backdrag control)
  • Snowplow (tilt/angle)

This kit uses the Power Beyond port and Return-To-Tank port. Once installed, the kit will allow you to use multiple functions (i.e. curl bucket and close grapple) in conjunction with your new one.

The included fully weatherproof Summit Hydraulics joystick handle replaces your existing handle, as it comes equipped with buttons for controlling your new third function. It easily attaches onto the existing joystick shaft with the included removable adapter bushings and adjustment screws. The joystick’s two integrated momentary push button switches allow you to open and close your cylinder with the push of a button.
