I have a MF31 which is the industrial clone of a 175. Need help to select proper gear to achieve 5 mph ground speed while turning the pto at 540rpm. It has the 3 forward geared tranny. Being an industrial it has 16.9-24 inch tires. I will be broadcast seeding with it. I sold the tractor that used to do the job so this the first time doing it with the 31.
 
if you have a gps you can use the speed indicator to check your ground speed,used mine several times with good results
 
Thanks for the reply. I figured it out thru trial error while using the spreader. 5th gear at 1200 rpm worked best and my lbs per acre was right on.
