Agree with Mike S. I use my 4400 primarily on turf but also on hard surfaces such as concrete and macadam. In 2WD the old axle would leave heavy (I mean **HEAVY**) rubber on these hard surfaces whenever the wheel was moved from straight ahead. It was worse in 4WD. I really think that the folks who continue to use the old axles will experience accelerated tire wear. Tires are not cheap. Kudos to my dealer who worked very hard to get me a new axle in minimum time. Kudos to this board for being instrumental in pressuring JD to acknowledge their error and replace a poorly designed front axle. Russ

I installed the 3rd SCV kit ($220.00) on my 4400 in about 5 hours. To adequately access the j-tubes, the seat and cover plates must be removed. A problem which cropped up was that most of the control handles are press fit to the controls and once they are removed they don't fit as tight as they did. Be sure to check the parts bags thouroughly - I got shorted 4 o-rings which held up production for a bit. The instructions and diagrams are adequate but not up to the standard of JD tech manuals. Althought the SCV lever and control line are a Rube Goldberg affair, the plumbing is well engineered and installs easily. I am very happy with the 3rd SCV unit. Good Luck. Russ

I took delivery of a 4400 this last week. Beautiful machine. The mfwd axle has a date of manufacture of 10/06/99. This machine tears up my lawn AND leaves rubber scuff marks on the driveway (concrete) whenever the steering is moved away from straight ahead. The farther the steering is moved towards lock, the more rubber is left on the pavement. My driveway was starting to look like the approach end of O'Hare airport. How is on turf you ask? The turf takes a beating in any turn effort exceeding 'moderate'. My turf is currently in a very dry state (no rain in the past month) and IMHO suffered less damage than if it had been recently watered and soft. The front tires (outside tread) show distinct wear just from 3 or so hours of mowing duty. Tire wear IS an issue. My dealer has opened a work order with Deere to rectify this problem. I understand Deere is attempting to differentiate axle replacements based on type of work performed by the machine - with emphasis placed on turf damage vice tire wear. If I were using my machine more as a loader on hard surfaces, my tire wear would be astronomical. The front tires, judging from the rubber left on (in) my driveway, would not last thru 3 months of daily service. Unacceptable. I would think if there were enough dissatified 4000 owners to band together, a class action suit would be feasible if Deere didn't resolve ALL scuffing problems regardless of type of service. Thanks for the information all.
