    2011 John Deere 85D. What could cause diminished power in drive motors/tracks?

    I have been noticing the speed and power diminish on the drive motors/track over last few month on my 2011 John Deere 85D even on full RPMs and power mode. Everything else seams to work ok and no problems with the engine or other hydraulics. Would the problem be something in the actual drive...

    Considering doing EGR Delete of 2011 John Deere 85D excavator. Good or Bad idea?

    I am considering doing EGR delete on my 2011 John Deere 85D excavator (Isuzu AU-4LE2XYSA-O1 engine) Is it a good or bad idea, and if I do, would it require a re-map or would the ECM be able to re-adjust the air/fuel mixture on its own after the delete?

    Can't switching axil/thumb operation from foot paddle control to right control stick buttons on 85D

    Hey mg2361 thanks again for the response. It is a swing wag... I just didn't describe it in the right words. So you are saying the only fix is to replace, huh? That sucks.. I just bought the machine, so not sure if it has been greased every 500 hrs, but if the amount of excess grease found on...

    Can't switching axil/thumb operation from foot paddle control to right control stick buttons on 85D

    ah.. I see.. Hey wondering if you may know regarding this... So, the left and right rotation on my excavator is little wobbly/loose. I mean like when I rotate and then stop, it kind of has that wear-wobble. And it's fine for general work, but for something precise like stacking up a retaining...

    Why does my AC pump turns on and off in my 2011 John Deere 85D, cooling not satisfactory.

    Why does my AC pump turns on and off in my 2011 John Deere 85D, cooling not satisfactory.

    Any one knows why does my AC pump comes on and off every 10-20 seconds or so regardless of what ac setting I have it on (even on coldest setting) resulting in not so cold air inside the cab? (2011 John Deere 85D) After the AC is turned on, right away the relay would click and the pump would...

    Can't switching axil/thumb operation from foot paddle control to right control stick buttons on 85D

    mg2361 thank you so much for your advice and especially for the instructions and the schematics that you attached.

    Can't switching axil/thumb operation from foot paddle control to right control stick buttons on 85D

    Thanks for a response. I really wish I could get my hands on those schematics. I looked all over the internet for those, but can't find anywhere. Unfortunately the only John Deere excavator dealer in my area is PAPE Machinery, and let me tell you, they have not been helpful at all. I had to buy...
