An industrial or an ag machine should hit 10,000 hours.
A CUT probably 7-8,000 hours
A SCUT like B or BX might hit 5,000
Probably need a decent bit of maintenance & a bit of luck to get there.
Homeowner machines are more likely to rot as they will be to wear out. I do side work with my
L4060 ontop of maintaining my 5 acres. The machine has paid for itself every payment & will be payed off in December. 5 years & I'm only at 800ish hours. So by my guesstimate it has around 40 years of life left.
I'd doubt that machine would make 3,000 hours before it rots, but thats another decade or 2 for most home gamer uses. Plenty of life left if you have some basic mechanical skills for maintenance. Value likely won't drop much over the next 5+ years if you don't abuse it either. Fine & cheap way to figure out if you need more of a machine later down the road.
