Lane Shark Return Hose Connection

[kubotaorangeisthenewblack]

Folks,

I have searched the forum and the interweb looking for the hydraulic tank return port on my tractor. I have also read the Workshop Manual's section on hydraulics and it isn't clear exactly where to tie-in the return line. The tractor is a MX6000 w/ a cab and it has a Kubota MX2132 Loader valve connected to a WR Long 3rd Function Valve. I also read through the Assembly Instructions for the Land Pride 3rd Function valve that describes connections to the tractor's Outlet Block and it is not clear when the return line should be connected. I am running a Lane Shark FEL Mower from a rear remote port for the supply but they advise to return to the vented tank instead of through the adjacent rear remote due to its restricted flow.

I tried connecting the return to the "T" (tank) port on my WR Long 3rd Function Valve (this is the way the Lane Shark kits are connected) but it dead heads the supply line from the rear remote.

My outlet block has three ports. The top left port (power beyond?) has a green dot next to it. The top right port (pump?) has a red dot next to it. There is also a third port at the bottom right that seems to have a black dot next to it but I cannot find anything identifying what it does. Any ideas?

Would the return line connect to any of these ports or should it be fed directly to the hydraulic oil tank?

I have tried to upload the assembly instructions but the forum says the files are too large.

Thanks in advance for any help with this!

The outlet block will have three ports:

1. Pump out to implement
2. Implement power beyond return
3. Implement tank return

Based on your description the bottom right port is implement tank return.

The Lane Shark would probably he happier if you can manage a direct tank return

Lane shark dealer recommended to me return Via hydraulic system fill/vent at rear of tractor.

Lane shark dealer recommended to me return Via hydraulic system fill/vent at rear of tractor.

The downside of course is that disables all devices downstream of the Lane Shark - e.g. remotes and 3pt....

Thanks everyone for your help and suggestions. I will continue to work through the hydraulic plumbing and hopefully get everything connected correctly. I will keep you posted on how this works out in case anyone else has a similar question.

Thanks again!

Sometimes requires making a fitting or drilling the fill port plug for the return hose. Make sure you have another plug when not using the cutter. Maintain a good vent.

Love to hear your feedback after using the cutter. Looked seriously at them before gong another route. My brush and limbs bigger and higher.

Thanks @Smokeydog and others.

I was able to plumb the hydraulics to get everything flowing smoothly. I spoke with a very helpful service tech at Lane Shark who confirmed the location of the return port on the outlet block. I looked everywhere for an clear explanation for this port and could not find it in my WSM or anywhere else. The lower port seemed like the return to tank port because it was where the lines were connected from the pressure relive valve on the loader assembly (I figured when the pressure relief valve opened, the hydraulic fluid should discharge back to the tank).

Initially, I connected to the port connected to the "T" (tank) port on my WR Long 3rd Function Valve but this dead headed the hydraulic motor. I attached a pic showing my tie-in using a #8 run tee fitting. The tech at Lane Shark said to test the cutter to ensure that the hydraulic fluid flows back to the tank unconstrained. To do this, he said to run the mower up to speed then turn off the flow to the hydraulic motor and if it is connected properly the blades should coast to a stop gradually. He said if the blades stop quickly there is back pressure in the system and the return to tank isn't correct. Fortunately, mine coasted to a stop so it is ready to be put to work.

Thanks again for all of the suggestions!
