calibrate in the following manner:
a) Set out two markers 88 feet apart.
b) Select the proper gear and adjust the throttle speed to give the following travel time as

NOTE: You cannot adjust the throttle much, as you need to maintain 540 RPM PTO speed. (A plus or
minus 20 RPM could be tolerated.)
1 MPH will travel 88 feet in 60 seconds
4 MPH will travel 88 feet in 15 second
