Zetor proxima 85 no hydraulic

[AlCapone]

Zetor proxima 85
been loading and unloading bales no problem
Went to tip up double ram trailer
Tip part of way then stopped rams went down ok
No hydraulic at all now
Plenty oil in system

 

[ladycrofter]

So the loader no working either? Does sound like the tipper ram was empty, level too low to work now. How are you checking the oil level?

The trailer worked ok a few days ago with different tractor
The zetor tipped a single ram trailer this morning no problem at all to unload dead cow at collecting centre

Sounds like your pump has cavitation

 

[ladycrofter]

That's a puzzle. I agree with @celtis man, sounds mechanical, air lock could be right enough. Don't think a Prox 85 has a lot of computery interlock sensor thingys.
Junk in the hydraulic filter?

We have a valtra do a similar thing and that had destroyed its own pump by swarthing inside
It could just be a blocked suction screen or filter

There's no lever on the side like the old crystals to engage or disengage the hydraulic pump?

Isn’t there a neutral when shifting the pump between 540 and 1000 also?
Been 30 years since I last used one.

Yes depending what the proxima gearbox use

 

[ladycrofter]

The neutral wouldn't explain it partly lifting the trailer I'd try equalising the hydraulics, then pull the filter out. Its a barsteward if anything like mine (Prox 95). But might save a callout.

Why?
My 77 will jump to neutral mid flow

Low oil level was problem

Low oil level was problem

Oh
You were lucky.

Where’s the dipstick?

Was on the seat

Probably just busy and didn't notice it leaking.

In his opening post, I quote
“plenty oil in system”
So not harsh.

He is a livestock farmer and always busy
Don't lambast him as it was working before

Are you sure

 

[celtis man]

Are you sure

I have not got a clue what he does
All I know is the zetor didn't throw a hissy fit because it was short of oil
If that was a leading brand like a fendit you would need a technician out to plug in the lap top and soothe the angst
