Deere has always built pretty good powershifts. I've got quite a bit of experience working on them in the large row-crops, and they are good units. Just like any type of transmission, proper maintenance and operation tells the tale. If you keep good oil and filters in them, and don't abuse them, they'll run a long time without problems. If you use el cheapo oil and don't change it or the filters often and abuse the tractor, you can ruin one in a matter of hours. They're probably a little more expensive to fix than a quad-range, but quad-ranges can have their own little quirks as well. How hard they are to work on depends on the tractor. The 8-speed powershifts have the clutch pack located in the front of the transmission, the 15-speed versions have it mounted on the flywheel. They're easier to pull and disassemble on the 15 speeds. Both versions require removing the rockshaft housing and either the cab or the cab floor to get to the brake pack. I think you could get one out through the cab floor, but we just pull the cab, as we have overhead hoists and it's just easier to pull the whole thing and have it out of the way. If you have any other questions about the powershifts, feel free to email me.
