5. Setup and Installation
Safety First:
Always ensure the tractor is turned off, the engine is cool, and the parking brake is engaged before beginning any installation. Disconnect the battery to prevent accidental electrical activation. Wear appropriate personal protective equipment (PPE).
The Fexhull Third Function Valve Kit is designed for straightforward installation. It connects to the power beyond port of your existing loader valve, allowing for simultaneous operation of multiple functions.
5.1. General Installation Steps (Consult a professional if unsure):
- Mount the Valve: Secure the 12V solenoid operated valve using the provided valve mounting bracket and hardware in a suitable location on your tractor, ensuring it is protected from damage and accessible for maintenance.
- Install Quick Couplers: Attach the quick coupler mounting bracket and install the male and female quick couplers.
- Connect Hydraulic Hoses: Connect the hydraulic hose assemblies from the tractor's existing loader valve (power beyond port) to the new third function valve, and then from the third function valve to your hydraulic cylinder or attachment. Ensure all connections are tight and free of leaks.
- Wire the Joystick: Connect the joystick handle's wiring harness to the 12V solenoid valve. Ensure all electrical connections are secure and weatherproof.
- Test System: After installation, carefully test the system in a safe, open area before operating with an attachment. Check for proper function and any leaks.

While the kit is designed for ease of installation, hydraulic and electrical systems can be complex. If you lack experience with such installations, it is highly recommended to seek assistance from a qualified technician or refer to detailed instructional videos available online for similar installations. Some users have found external resources, such as YouTube videos, helpful for visual guidance.
6. Operating Instructions
Once the Fexhull Third Function Valve Kit is correctly installed, operating your hydraulic attachments becomes straightforward.
6.1. Basic Operation:
- Connect Attachment: Securely connect your hydraulic attachment (e.g., grapple, auger, snowplow tilt, snow blower) to the quick couplers of the third function valve.
- Start Tractor: Start the tractor engine and allow the hydraulic system to warm up to operating temperature.
- Engage Third Function: Use the momentary push-button switches on the joystick handle to activate the third hydraulic function. Pressing one button will extend the hydraulic cylinder, while pressing the other will retract it, controlling your attachment.
- Monitor Performance: Observe the attachment's movement and the tractor's hydraulic system for any unusual noises, leaks, or performance issues.
This kit is commonly used to add functionality for:
- Grapples
- Augers
- Snowplow tilt
- Snow blowers

7. Maintenance
Regular maintenance ensures the longevity and reliable performance of your Fexhull Third Function Valve Kit.
- Inspect Hoses and Connections: Periodically check all hydraulic hoses for wear, cracks, or leaks. Ensure all fittings and quick couplers are clean and securely tightened. Replace any damaged components immediately.
- Check Electrical Connections: Inspect the wiring harness and Deutsch connectors for corrosion or damage. Ensure they remain weatherproof and secure.
- Clean Components: Keep the valve and other components free from dirt, debris, and excessive moisture.
- Hydraulic Fluid: Ensure your tractor's hydraulic fluid is at the correct level and is clean. Refer to your tractor's owner's manual for recommended fluid types and change intervals.
- Dust Caps: Always use the provided dust caps on quick couplers when not in use to prevent contamination.
8. Troubleshooting
This section addresses common issues you might encounter with your third function valve kit.
| Problem | Possible Cause | Solution |
|---|---|---|
| Attachment not responding or slow | Low hydraulic fluid level; clogged filter; air in system; faulty electrical connection to valve; valve malfunction. | Check hydraulic fluid level and condition; inspect/replace hydraulic filter; bleed air from system; verify electrical connections and power to the valve; consult a technician if valve is suspected faulty. |
| Hydraulic fluid leak | Loose fittings; damaged hoses; worn O-rings or seals in couplers/valve. | Tighten all fittings; inspect hoses for damage and replace if necessary; replace worn O-rings or seals. |
| Joystick buttons not activating valve | Loose or corroded electrical connections; faulty joystick switch; no power to the valve. | Check all wiring and connections for continuity and power; test joystick switches; ensure tractor's electrical system is functioning correctly. |
If you encounter issues not listed here or are unable to resolve a problem, contact Fexhull customer support or a certified hydraulic technician.
