Does anyone have any advice on fixing metal contamination in the HST system.  I know the best way is to get a completly new tractor.  Because that is most likely not going to happen what parts /components need changing? I imagine because it is an HST there is a ton that will need to be done.  In your experiance how well does Deere handle this problem?  Have they admitted that they have a problem here?  I fully expect to get brushed off by the dealer saying that it is a normal amount of metal even though my friends with tractors say otherwise.  Thanks all in advance for the advice.
