Rear Hydraulic Valve Kit with Front Third Function for Kubota B3300 Series Tractors

Rear Hydraulic Valve Kit with Front Third Function for Kubota B3300 Series Tractors

Kubota B3300 w/ LA504 Loaders

This all–in–one rear remote valve kit with front 3rd function is designed to install on your Kubota B3300 Series to add rear remote connections and a third function. This allows you to easily control various hydraulic implements in the front and rear using our Summit Hydraulics joystick and/or switchbox controls. You can add two, three, or four rear remote coupler sets to your machine and a third function in the front.

To support this kit, you can purchase one of our hydraulic cylinders. You can add a top link cylinder kit to your Kubota tractor. Other top link cylinder kits are available.

Third function commonly used to add:

• Grapples
• Augers
• Snowplow tilt
• Snow blower

(Not designed for tractors with cabs or closed cabs)

This kit requires minimal basic tools and mounts directly to your ROPS. It can be installed in 3 hours (estimated), and acts independently from the other hydraulic valves on your machine.

This kit will connect to the power beyond pressure port from the tractor loader valve, and the return port on your Kubota B3300 Series Tractor. The Pressure and Return ports are often connected to each other via factory hardline. Removing this hardline will allow for an additional hydraulics to be added downstream.

NOTE: The rear remote connections on your machine will be 1/2″ Body AG ISO 5675 Female Couplers. The hoses for your implements will need 1/2″ Body AG ISO 5675 Male Couplers. The mid mount and loader mount use 1/2″ Body AG ISO 5675 Couplers.

Kit includes joystick handle that replaces your existing handle and has two or four integrated momentary push button switches so you can open and close your cylinder with a push of a button. The joystick would control the first and/or second function/spool of our valve. Our joystick handle has a comfortable ergonomic design and is fully weatherproof. The handle will attach onto existing joystick shaft using the removable adapter bushings and adjustment screws.

For different variations, the kit also includes two or three button momentary rocker switches that spring automatically to the neutral position.

NOTE: One spool is dedicated to the front third function.  The remaining spools (3, 2 or 1) will be dedicated to rear remotes.
