I have a 2011 5083 with large loader, and 595 JD backhoe with 60 some hours on it now, I have owned it for 3 months, and it has spent 5+ weeks in the shop due to hydraulic issues. JD replaced every major component and it still has issues, hydrualic fluid is white because of the foam, growling when it gets warm. Initially it seemed as if they had identified and corrected by putting an anit-cavitation device on it.
We identified the problem the day it was delivered, dealer said it was probably air, run it. I continued to complain and they sent someone out to look at it, he agreed that the backhoe was not running correctly and he heard the growling. This is all before the 5 weeks in shop and parts swapping.
I have had it back for about 2 weeks and noticed an issue again, dealer came out yesterday and said it was 3 gallons low on fluid, but not sure where it went since we have not seen any major leaks. They filled it and the hydraulic fluid is still foamy and it still growls when it gets warm.
JD Corp has indicated verbally to dealer that they will cover 2 months payments and extend warrenty by 6 months. That is great, but machine is still not running right
