One of the most important aspects of this forum is communication. Heretofore, unavailable information to the vast majority of tractor owner's across the country regarding the pros and cons of any particular make/model as well as solutions for any particular issue.
In that manner; a heads up - to other 5000M series owner's. My 2011 5075M is at the local JD dealership for warranty repair of the hydraulic system. The problem is the hydraulic pump will lose the "prime" and will not power the loader, the 3pt, the transmission or the steering until the engine rpm's have been ramped up to 1,700rpms or so for approximately 20-30 seconds. After that, all hydraulic functions are just fine... until you shut the tractor off. Upon restart - you have to go through the fast-idle drill all over again - until the hydraulic pump starts functioning.
If you leave the tractor at idle; it will sit there until the fuel is gone.
The local JD guys have only had it for a handful of days (including the weekend) so, I don't have a definite solution to the problem - yet. They initially figured that the sump filter was either plugged off or damaged. Except... the 5075M does NOT have a sump filter! The hydraulic pump is integral to the filter. They are mounted just in front of the rear axle and share a common housing that allows the hyd pump to pull filtered hyd oil directly from the filter.
I thought the problem was J20C hyd oil. The standard viscosity hyd oil gets just like cold honey - heavy, and thick - with the winter temps. So, I drained it all out and replaced it with J20D - LoVis and a new filter. Even at 45F and a warmed up transmission; the pump wasn't doing what hyd pumps are supposed to do!
So, it was time for the JD shop to work out the problem.
I'll keep you all posted on the outcome.

Shoot, I figured I was in Owner/Operating forum! Wrong address... right town!
