Couldn't agree more stam, people read too much into hours. It's the same with cars/trucks.
It's the care and maintenance it's received through its life that really counts.
I've had trucks with 4000hrs and 3 years old that were beyond economical repair due to neglect but looked after machines 15 years old with 16k hrs plus and still run like a Swiss watch and capable of working all day every day because they have been maintained properly, to excess even.
