Tractor speedometers?

Not very under load because of tire slip, unless it's new enough for radar or GPS. Plus tire size, even differences between brands affects it some. I have a speedometer on my phone

I?ve went from 15.5.38 tires to 18.4.38 tire and according to just the free speedometer on a smart phone app I haven?t picked up any speed at all . I have not tried it without an implement in the ground so I guess I really didn?t think about wheel slip

Your app ain't too smart. Any circumference change is changing ground speed. Check the tools button on your app to see if there's an adjustment bar. If not you need to find another app.

I can?t find one that will work with slow speed very well . I have a hand held gps that will measure speed but it was dark so I didn?t try it yet
