			Go back to post #2. These are Yanmars with PowerShift and multi-speed PTOs that are engine RPM controlled to the final output of 500RPMs at the PTO.You need to figure out which PTO gear is 540 at the rated RPM; but for the ground speed, it depends on how fast you can run through whatever you are cutting and gives you a good cut. The pto speed is independent from ground speed.
Howse Bush Hog is going to be rated at 540 rpms.
