I have a friend who is still running his D8H commercially. He says parts are still available; aftermarket if not Caterpillar, and used parts are still plentiful. Undercarriage as always is expensive and difficult to find used in good condition. The D8H is a good tractor, I think that if it checks out go for it. π
Happy 'dozing,
