We have two floaters with scales and a dry fert box with scales.

What is the point of a scale if it is off?

They get used while moveing on all three rigs.

One is used while moving to adjust the application rate, the others are for double checking loads and acres covered.  

All the feeder wagons I have seen get turned on and left on until done with chores.  

Could send johnny up here, got a real nice terragator he could run starting on Monday with the scales turned on!!   LOL
