Auxiliary Hydraulics

jgbanshee · Jan 11, 2005

I have the rear hydraulics on my 4300 for the backhoe setup. I was wondering if I can use that hookup and run hydraulic lines up to the loader for use with a snowplow or grapple. I think the mid mower uses that to lift. If not what is the easiest way to add hydraulics at the front of the loader.

Why not tap into one circuit of your FEL control and use a electric diverting valve? There are more than a few articles here at the TBN site showing how to do it.

I have a 755 which I am adding 3 circuits to. I read a thread before I had my tractor but I can not find the previous thread covering this. Can anyone guide me there? thanks

If the ports are for a backhoe, they are probably Power Beyond ports, and have no valve to control them, the valves (SCV's) are on the backhoe. These fittings just provide full oil flow.

Is there a loop of hose that connects the 2 fittings at the rear of the tractor?

If you do however have a extra handle that operates these remotes, the you can surely run hose to the front of the tractor.

That is the easiest and cheapest way if you if in fact have the rear remote and not a Power Beyond port.

The other cost effective way is to add a diverter to the FEL curl/dump circiut.

I did it to mine, and detailed it in this POST

And Mike (PineRidge) did his in this POST

I hope this helps some...

When you say you have rear hydraulics, for a backhoe, then you mention they are there to lift the mower deck, you made it really confusing.
What do you have on your tractor? Backhoe, (which means you have power beyond), or a mid mower? (which means you should have a 3rd scv) or both?. Is there a lever on the fender that you use to lift the mower deck?

If you DO have the 3rd SCV, you certainly can get the kit from Deere to bring that circuit to the loader boom to run a grapple or angling blade or whatever. BW14715 is the kit with the 3rd function oil lines for the 430 loader. They don't show this kit for the 420 loader though.
If you do not have the 3rd SCV, and you have power beyond, then other options include adding the 3rd scv, (LVBM19694)
or using the above mentioned diverter to operate the grapple.
The first step if finding out what you have already.

I have both the Power Beyond and the 3rd SCV with the lever on the right fender.

Where do you get the part numbers for these kits as well as any other part numbers I may look for?

If you have both, then you are all set! All you would need is the 3rd function lines for the loader. ( It was the 430, right?)
If your mower lift kit is still on the tractor, just unplug the hoses going to that cylinder and route the new hoses for the 3rd function to the rear of the tractor. I believe the kit comes with a plate that adds couplers to the mid mount loader couplers, so you will then have 6 hoses to unhook to remove the loader.
