INTRODUCTION
Tractor engines are designed to reach maximum power at PTO speed (1000 rpm), and most tractors are capable of
engine speeds from 10 to 20 percent over PTO speed. A rotor speed of 2000 rpm is recommended. It will be necessary
to operate tractor PTO at approximately 1100 rpm.
The flow control valve controls the feed rate to keep the tractor at its peak power point.
