Tractor Loader 3rd Function Hydraulic Valve Kit

Allows the use of a 3rd function such as a grapple or 4 in 1 bucket. This kit is for tractors that use less than 15 GPM, larger tractors will require the upgraded option. Call for more details (you must have your tractor model and loader model numbers when ordering.) The 3rd function kit connects to the power beyond port of your existing loader valve. This is a full 3rd function kit allowing you to raise/lower, dump/curl, and open/close at the same time. The hand grip with three position rocker switch is designed to fit over you loader joy stick and be screwed on.
**Rather than leaving the hoses/couplers loose, the kit now includes a bulkhead plate to rigidly mount them to the tractor loader. Some of the bulkhead plates are not tractor specific**

Our valve kits are powered by the power beyond port. The purpose of the power beyond port is to provide auxiliary power to attachments beyond the loader valve. Example: 3 point hitch, rear remotes, backhoe, etc. The majority of tractors / loaders will continue to supply fluid to the power beyond port at all times. It doesn’t matter if you dump, curl, float, go up and curl at the same time, etc…. With that being said there are some that will not. Some will stop sending fluid to the power beyond port if you go up and curl at the same time or float. ( do more than one function at a time) and instead the loader valve will dump all the excess fluid back into the tank. This means you can only use 2 functions at a time. It’s still a 3 rd function valve since you are adding a 3 rd set of hydraulics to the front of the tractor, you just don’t get to use all three functions with one motion of the joystick. Example. You can go up and control my valve at one time, curl and control my valve at one time, up and curl, etc. If you are concerned about this the way to check it would be to connect to your rear remotes with a attachments and run that attachment. Then try to go up and curl your bucket all at the same time. Not counting once you have gone all the way up and curled all the way back since then your relief valve will kick in and all fluid get diverted back to tank then. “Southwest” on the joystick. If your rear attachment stops or significantly slows down then you have lost the fluid to your power beyond port and you are limited to only using 2 features at one time. If everything continues to work then you still have fluid going thru the power beyond port and you will be able to use all three functions at one time. Example: (Up, curl and open attachment). Long story short is the customer could not use all three functions with one motion of the joystick. It’s all about what the tractor loader valve does…

Our valve is made for momentary use like open / close or left / right operation. It is not made for rotary implements like augers. The valve has a extremely tight tolerance and if held down to use a rotary attachment it will heat up and swell causing the valve to seize. Thanks!

Attn: These are custom kits available for many tractor makes/models. Call us to see if a kit is available for your tractor.

NOTE: If your tractor comes with a backhoe as standard equipment like the Kubota L39, then the hose lengths will be correct. If you have a backhoe that is an option or later added on, then the hose length, hose end and valve mount may not be correct since the valve kit is designed for the loader when there is no backhoe present.

5 of 5 Installing on a JD 4310 February 7, 2020
Reviewer: Steve P from Charlotte, NC United States  
The mechanical connections are easy but the JD engineers are evil.

To get to PB ports you have to:

- Remove the ENTIRE seat assembly including the operators station pan under the seat.

- Couldn't remove the seat tension knob, so I slit the rubber above it on the bellows to get the bellows off. The 3pt Lift speed knob pulls off.

- Seat bellows = not fun to remove.

- Pry the cap off the speed range lever to get to the nut to remove.

- Couldn't figure out removing the knob off the 3pt height lever so I lubed it w/ WD 40 & eased it through the pan slot.

- Station pan has a stupid bolting configuration at the deck.

- Once at the PB connections,  R side port is NOT easy to get a wrench on. You can but not easy.  

- Fully tilt the Grapple back to test fit the QC's mount.  Angle of location important to avoid hitting grapple frame.  

Past JD's cruelty, it's a 30-45 min install.

5 of 5 You get what you pay for! February 6, 2020
Reviewer: Chris W from Valley, AL United States  
I looked and researched much about 3rd function valves before buying from everything attaches. I mean these things aren't cheap, I feel that I got my money's worth. Fits my Kubota L3901 with the 525 loader like a glove. Instructions were easy to follow, everything needed was included, the only thing that I could recommend is some large zip ties to secure the hoses to the FEL lift arms.
