John Deere 4650 stops moving

[archerivo]

Hello everyone,

I have following problem. I have a 4650 John Deere, it was driving normaly until one day as I was driving the red STOP lights on and the yellow warning light, and the traktor stops moving. The engine is working but the power steering stops working and the traktor doesn`t want to move forward or backwads. And the only way to get it working is to stop the engine for 1-2 min. and when i start it up again everything is normal for about 5-7km.

After I changed the transmission oil and filters it is better than before, but for max 10km and stops again. Is it possible the filters to get dirty again for a week from the change?

Is it possible a mechanical or electric valve to open somewhere on the oil circuit and to stop because of that?

Thanks in Advance
Ivaylo

It`s a 4x4 Powershift. When i opened it, there was a lot of litter inside, I cleaned it and put the plastic one and the new filters. After that I put new oil in.

On a PS trans you need to check pressures in all gears.
