Zennoh zl2201

[terrywhitejr2000]

Hello all I have a zennoh zl2201 tractor, when I start it the hydros work fine. After running it for 15 minutes or so the hydros will not respond. If I turn the tractor off for a while the hydros will work the next time I try to use them. Does anyone have any idea as to what can possibly be going on?

Either the pump is failing or more likely the 3 point control is adjusted improperly and it's overheating the relief valve and causing it to fail.

Thanks where would the relief valve be located? According to the images on the web its attached to the front end loader but I dont have a loader.

What are the chances its just a dirty screen? I have taken the screen out to clean it and upon removal I found it to be very dirty. I have ordered on from my local store but I am told it want be in until late next week. Not sure how it all plays together but I am hoping that this would be the issue.

I also found the hydraulic fluid was the color of chocolate milk not sure if its suppose to be that color.

The relief valve will either in the three point control or close to it, you'll have to give me some pictures of around the rear to figure out your configuration.

Yes a dirty suction screen will play a role in bad hydraulic operations.

Yes that would denote contamination, probably water.
And water and Hydraulics do not play well together!
