Rear Hydraulic Valve Kit with Front Third Function for LS MT335, MT340 Series Tractors

Rear Hydraulic Valve Kit with Front Third Function for LS MT335, MT340 Series Tractors

Fitment: LS MT335, MT340 Series Tractor

NOTE: This kit was designed on a tractor without a Backhoe. Potential hose length, and hose routing interference could occur. Please contact us if you see any issues during installation.

This all-in-one rear remote valve kit with front 3rd function is designed to install on your LS MT335, MT340 Series Tractor 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.

Third function commonly used to add:

• Grapples
• Augers
• Snowplow tilt
• Snow blower

(Not designed for tractors with cabs or closed cabs)

The kit requires minimal basic tools and no prior hydraulic experience to install. It will mount directly to your ROPS Bar. The kit will act independently from the other hydraulic valves on your machine.

LS Tractor w/o Backhoe will connect to the power beyond port on the loader valve and return to tank port. 

LS Tractor w/ Backhoe will connect to the rear remote using the two “quick connect” couplers. These are the couplers often used to connect a backhoe and then are connected to each other when the backhoe is not in use. 

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 3/8″ ISO 7241-A Style Couplers.

Kit includes joystick handle that replaces your existing handle and has two integrated momentary push button switches so you can open and close your cylinder with a push of a button. This joystick would control the first 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 one, 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.
