UPDATE 11-6-17
After using the Workmaster 50 for a few months since last shop visit. and a issues still plaguing the thing me and the dealer came to terms. We went ahead and swapped it for the 60 and this 50 went to the shop for the last time Friday. I gave it another 20 or 30 hard (but not abusive) hay baling, brush hogging, road grading hours before i gave in and called the dealer. Was it the right thing to do? I will never know.... but all i can say now is that i am completely satisfied with my dealer. He done me right on the swap where it counted $$$$, and tried every way possible to make the process as painless for both of us as he could. In the end i think his Shop did try all they new to do, but they just couldn't squeeze a bad lemon and i have nothing against them. We actually may have fostered a better relationship by getting to know each other a little bit.
So for future reference, If any of you find yourselves with a 2016 Workmaster 50 with a 611tl front end loader on it and the hydraulics start jumping and the gauges start flashing and beeping at you for no reason other than you started it up! Or if you just cannot figure out where that 1/4 gallon of ani-freeze is coming from blowing in the wind every time you rev above 1000 rpms. Send me a line and i will share with you the serial number for the nightmare i had. and hopefully New Holland finds it a home/grave before any of you do.
