Engine Horse Power not as advertised

[85Hokie]

So….lets see if I can do a better job…..on my question!
checking used Kubotas both equipped AC cabs.
2019 M4-071Delux has a PTO HP advertised and operater manual documented at 60.
535hours on this tract dashboard.
2021 M6000-HST has a PTO HP documented at 51.8.
237hours on dashboard.
Apparently when the M4-071 was tested using a water dyno tester at the PTO shaft it only produced 46HP at maximum rpm.
So….what is the true PTO horsepower???
Is it worth while to do a dyno test before a used tractor purchase?
Hopefully I asked my question correctly.

you keep say M6000....... as pointed out - no such animal!!!!!!! There is a MX6000.......... yes that little M makes a difference.

data on that :

On the 2019 M4-071Delux if your not getting close to 60HP then there is an issue with the engine or the clutch.
Or there is an issue with the dyno or the guy running it.
