I had two Bobcat excavators 341 and a 337 that both had over 4000 hrs on them when I sold them 5 years ago. My brother-in-law has the 337, and it still is running strong pushing 5000 hrs. Both of them have Kubota Diesels in them.What are typical figures(hours) for example the 26hp 3cyl in the ZTR mowers? Assuming one stays on top of PM's. I've got 510hrs on mine(2008) probably just broke-in good.
