LB2204 - Auxiliary Hydraulics

KiotiOwner · Dec 9, 2006

I acquired a Kioti LB2204 Tractor with a FEL (Kelley DL2000) which is connected to the auxiliary block. I recently purchased a 3PT LW6 backhoe w/o PTO hydraulics. I would like to keep both implements connected to the hydraulics. Is there an easy way to do this? Could I T off off the aux? All suggestions would be appreciated.
Thanks, Jim

You can T off it but you have to do it correclty or your hydraulics won't work correctly. The Hyd flow really isn't that high on this tractor only 6.67 GPM. How many hoses are running from the hyd block to your loader control valve?

There are three hoses.
1) Pressure Port to IN on FEL
2) Neutral port to BYD on FEL
3) Tank Port to OUT on FEL

Thanks, Jim

You can't tee of pressure lines. The loader valve, backhoe valve, and 3pt must all be in series with each other. You can also eliminate the 3pt from working but the loader and backhoe must still be in series with each other. One more thing, backhoe valves typically do not have power beyond capabilities so they are typically placed between the loader and the 3pt withthe 3pt being removed from the circuit. See my second example below.

If you want to use the 3pt while the backhoe is connected (not recommended) follow these steps:

Disconnect the loader power beyond line from where it connects to the tractor's hydraulic block. Reconnect it to the backhoe pressure inlet. You can either use a new longer hose or join the two hoses together with a union fitting.
Connect the backhoe outlet port to the trractor hydraulic block where the loader power beyond hose was connected.
You have now placed the backhoe in series with the other valves in the circuit.

If you are not interested in having the 3pt work while the backhoe is connected (this is the most common way to do it) then connect as follows:

Disconnect the loader power beyond line from where it connects to the tractor's hydraulic block. Reconnect it to the backhoe pressure inlet. You can either use a new longer hose or join the two hoses together with a union fitting.
Connect the backhoe outlet to the loader valve's return to tank line where it enters the transmission. This line can be teed and is the ONLY line that can be teed.

If you want to disconnect the backhoe make sure you reconnect the loader power beyond line back to the hydraulic block. Do not run the tractor unless the lines are all connected and the fluid has a path from the pump thru the laoder valve then thru the 3pt. Failure to heed this warning will, depending on your hose fitting configuration (QD's or no QD's), you will either have a big mess or you will destroy the pump.

If this was my installation, I would place QD's strategically so that connecting and disconnecting hoses will be easier.

Thanks for the information MadReferee.

Why is the first configuration not recommended?

I will be using QC's as I would like to disconnect the backhoe when I'm not using it.

Sounds like a PTO configuration would make sense especially since I am considering some other 3pt implements.

Thanks Again, Jim
