another 5103 question

[deerefan]

I was @ Stonehams, a site for JD things and info, and I noticed they had the 5103 rated at 46 engine 38 pto horsepower. I bought the tractor with the impression it was 50 engine, 42 pto horsepower. Which is it? Do they take different measurements to obtain their figures? /forums/images/graemlins/confused.gif

<font color="green"> JD</font>'s site states:
Advertised PTO HP (kW) @ Rated RPM 42 (31.32) @ 2400
Advertised Engine HP (kW) @ Rated Speed 50 (37.29) @ 2400

Those are the numbers i usually refer to. Just don't get why there are so many numbers floating around!
