Tires Speed accuracy with different tires

[thcri]

The speed is only part of the equation for spraying and putting on fertilizer. Example fertilizer spreaders tell you where you should be on speed but the type of fertilizer can change that. I have found that with my spreader and tractor the best thing to do is to use low range and go as fast as the tractor can go in the low range. I usually end up with just the right amount of fertilizer that I want to spread. I know I am no where's close to what the spreader says to use as far as speed.

I did use my GPS to determine what speed I was at in each range just for my own information.

Since radar was mention, a lot of larger Ag Tractors use ground speed radar to tell them actual speed. This is mostly use for planting and applying fertilizer etc.
