Engine speed will be the same 2200~2400 rpm 'PTO speed' regardless of which pto gear you choose. Look for the ticmark on the tachometer somewhere between the standard 2000 and 2500 rpm marks.
You probably know this but - only the Japanese Yanmar tillers (and maybe some other Japanese brands) are able to run at the higher pto speeds. American implements for small tractors are all designed for 540 pto rpm maximum and running them in a faster pto gear is dangerous.
But based on Winston1’s engine rom’s to obtain 540 pto rom’s, you could reduce engine wear and fuel consumption by reducing the engine rpm’s yet still generating the 540 pto setting required for the US build implements.
