Hi all

We currently have 3 S680's which are 1 season old and 2 of these combines are on their third pro drive gear box each. The gearbox seem to seize and the wheels lock.

When the pro drive gear boxes were inspected bolts appear to have worked loose and gone between the gears locking everything up.

This has been the case on each occasion and john deere don't appear to have a solution at this stage so we are told.

Has anyone else experienced this issue?

I can post pictures tomorrow to better explain the situation if that helps

S690 broke pro drive in first year at about 150 eng hrs. Something broke teeth off gears in there. I never did ask what they found out. It seemed to be a bit of a secret?? Got a new box from another machine, (not one box in spares in AUS that year):mad::mad: They mucked with this box for ages (months) as it was noisey and very clunky on gear changes. Finally got another brand new box after much much complaining and its all good so far. Other pro drive in 9870 has 5500 hrs on it and is still good. But I much prefer the old style hydro.

I was quizzing my dealer about this a while back when looking at a S680 and he said they have had a handful of failures, all of them have been machines doing alot of road work while towing comb trailers. I'd be interested to know if that rings true for those that have had failures?

No. Not the case for us. Machine is trucked everywhere.

The pro drive issue has been going on since the pro drive came out years ago, most of failures have been park brake or the bolt failure and bits going through other components. It's disappointing that there are new machines still having the same problem. Deeres fix when fails mentality is going to be their demise. Good comment Don 9,8,7...., regrettable but so many of the machines out there seem to be like that :(

One of mine popped at 450hrs and this machine had not done any roadwork, high respected Aus technician witnessed it all. Lost gear case pressure at first, could not solve myself so called on the tech. He tested all pressures and diagnosed as a faulty sensor as it was only 2psi below threshold. Spaced and fixed the low pressure warning, went for a test drive 20 minutes later she locked up. We removed the drive face plate 2 bolts had worked lose and gone through the system. Changed out the drive and up and running again within 15hours. Spoke to the tech again at the end of harvest, he worked on 5 others, all the same.

It's all good if your lucky enough to be covered by warranty and your on your way back to the shed when it fails but it just [email protected]!/ me when things are out of warranty and it's a common failure and they tell you your on your own, mean while your having to hire other machines or giving away work. The worst thing about the Ag industry is it all has to be done yesterday so we don't have time for the fix when fails crap, if your product has a fault don't keep it a secrete get some preventative maintinence procedures in place so it's not a freaking surprise for the guy who staked his lively hood on your product, that goes for all manufactures not just Deere. A mates 9870 just **** the water pump looks like a new motor, I started investigating it seems to be very common so at 2000 hrs replace your water pump on Deere machines easy fix instead of replace the motor at 2300hrs :(

I have never every heard of a John Deere Pro Drive break, ever. They are 100% reliable 100% of the time. Its the red guys that are making this up.

How is that Don? Thought I would give you your FJ fix for the day. Lol

Can anyone tell me how I can put up a picture so I can shed some more light on the issue.

whilst we do a bit of road travel all the issues we had were really on the first farm they worked at

Notice EVERY failure listed on here is from Australia? That's interesting....
Really bugs me when people make excuses for stuff....

You called that one Don, although he is VERY predictable.:rolleyes:

FJ don't you trust other people to answer the JD questions? Maybe some of us want to know when people are having issues so we can avoid it ourselves.;)

You are as predicable in making fun of me I guess as I am of giving you positive feed back from a tremendous amount of seat time and a ton of other owners.
Just trying to reel you back in FJ.;)

I do appreciate your knowledge on here.:)
