3520 / 300cx raise prob

[Chris robinson]

i have a jd 3520 w/300cx loader e-hydro and the loader bucket won't raise up over apprx. 36". it happened once before I loaded it up and took it to my dealer and when I took it off the trlr and cycled it up it raised to max highth , had it serviced and about 6 hrs later it is doing it again. any one experienced the same prob ?

No but it could be due to a bad pump that is performing intermittently?

Disconnect and and reconnect your FEL hydraulic quick connects. Once on my 3320 I had popped one loose running over some brush, and the FEL would only lift a couple of feet and then stop like it hit something. I thought I had broken something for sure. I looked around and saw one of the QCs just barely popped off its seat. Pushed it back on and problem solved.

Welcome to TBN Chris

I suspect Cocre is onto the problem. Slightly unseated QD's are usually the first cause of problems like this. The other is low fluid level-but that would not be intermittent.
