A way to isolate the loader control?

[Zebrafive]

I don't have an E-hydro, so I don't know if you can/should tow it at all even in neutral. RESEARCH first

Well, I got the tractor to a good spot for repair. I still can't see precisely what is wrong or where the leak is originating from. Does anyone have a manual or procedure for removing the shroud that covers up the valves? It looks like it requires removing the seat to get the whole thing off. Looks like the type of job I'd rather have a bit of guidance for

Can you see about where the oil is coming (leaking) from?

Is it from underneath the seat?

Yes, remove the seat and the cover if it is coming from under the seat.

Can't be much help if you don't isolate where it is leaking, and if it is a busted hose, or coupling.

What functions do not work......FEL, hydrostatic, 3 ph, steering ???

Are you empty of hydro fluid?

Was there an object under the tractor when you pulled it out?

Pics of the situation would be most helpful at this point.

 

[adegiulio]

I followed the rigid metal tubes that connect to the hydraulic hoses for the loader. They are all solidly connected to the valve or manifold or whatever it is they connect to. The fluid itself appears to be shooting out from behind that. I can't see exactly where from any angle.

as the valve would be blocked not alowing any flow in the neutral position as you were pushing is it possible that you where pulling the handle as you were grading. I think what likely happened is you may have taken out the large o-ring that acts as a seal between the valve body and the tractor. You may have to remove the wheel to access. Remove the 4 steel lines from the valve, these are banjo bolts with a copper washer on each side. then remove the valve to check the o-ring between the valve and tractor.

 

[adegiulio]

Well, I found the problem. The top of the SCV just blew right off! I know it sounds crazy, but a big chunk of metal blasted off, as opposed to a fitting or a hose blowing. WOW.

 

[beenthere]

That is a WOW for sure.

Would you post a pic from a bit further back so we can see where this broken casting sits?

Is there a matching piece under the broken piece? One mounting bolt between?

I would expect Deere will replace that part for you.

Is this the part that broke? That gold piece laying there is throwing me off.

 

[adegiulio]

Yes that is the part. The tractor is well out of warranty, so I'm not holding my breath on Deere covering the part. I'll certainly press the issue though. The gold part connects my additional hydraulics controller to it's valve (I have a clamshell bucket which this controls)

 

[beenthere]

That addition of the clamshell controller may take it out of replacement by Deere, but it doesn't seem to be a typical failure of good cast parts.
I'd not be surprised if Deere doesn't replace the part at least, so they can inspect the broken part.

 

[adegiulio]

I don't know why it would affect anything. It's a Deere installed option.
