Well i have cooked 3 or 4 of these pro-drives. I do believe they failed from operators being a little extreme. The most sensitive area is the service brakes. Operators tend to rest there feet on the brake peddles which are way more aggressive with them using actual hydraulic pressure instead of a master cylinder setup. This system disintegrates brake pads very quickly, contaminating the system with brake linings. Then it is down hill from there if you don't catch it in time and repair the pads and flush the fluids. Since training my operators to stay off the brake pedals and NEVER use them on the turn row I have yet to lose another one. My 2 cents..... I'm sure there are other failures but mine i believe are from abuse after inspecting them....

And Dangerous!! The guy i was speaking to said he was lucky he had a 40 ft front on otherwise it would have landed on it's windscreen!!! The front dug into the ground about 2 ft. 4 ProDrives in a season (800 hrs) before they traded him out

Ouch this is sounding like the Gm recall BS.. They better figure that out quick, might be why it's kept so secret...

Think the concept is a great idea, and once it's dialled in, it will be popular by all colors

After working on well over 50 prodrive machines the only one I have seen with a failure was one from a neighbouring dealership that did not have the PIPs for the prodrive done. Most opererator complaints were usually fixed with a little training and/or software. But there is always the Friday afternoon ones that slip through the cracks.

My machine maintainence is very strict, so you can delete that theory. I have been driving combines for 22years without a transmission failure so you can delete operator error. Deere took my destroyed pro drive away to investigate and they identified they had a fault, however would not let the fault be known. They were very obliging and quick to act, some might say to keep me quiet. Currently pre season servicing and part of that is going to be pulling the pro drive down and checking bolt torque hopefully We find them loose so I can start something up again because I really believe they have an issue in Aus.

Yes, we have had that exact behaviour. I dare say they are shitting big bessa blocks about a potential class action from many customers as this is a big safety issue. I dare say swoosher, you would have got the subtle mail notice about possible park brake failure on pro drives and try and park on level ground.!!! Someone with reindeere undies told us how to word our letter to JD when trying to get the 2nd new box. We were instructed to keep useing the term "safety issue" and "dangerous". It seemed to work. Got the box.

Bought another JD this year too so not a Deere basher. Just get this **** sorted already.

There is definitely an issue bigswoosher, Have a close friend who had a pro drive failure in an 9770 and know of two other contractors who have had multiple pro drive failures in S series machines. Don't know exactly what happened, but was told 4 bolts worked their way loose and the heads broke off and went through the gearing apparently. Owners are now battling with John Deere to get warranty. Chesterfields in Moree were very impressive in being able to get my mates machine going again quickly , however there is no reason why it wont happen again.

Not a basher either phantom, bought another myself this year. Still just a bit concerned the problem hasn't been solved, so I'm digging at the moment.
Chesterfields Goondi replaced mine and I guess it's because of this type of service that I keep going back to Deere.

Maybe you should sic your dog on Deere, the one in your avatar.
It can feel like a fight like that when dealing with issues like this!

So a friend of mine is just signing the paperwork on two 2010 9770s with around 400hrs today, will probably drive them home (about 80 miles). Is there something they should be checking or doing with Deere before they do this?

Why is there never time and money to do it correctly but there's always plenty to do it again
