Drag Chain Distance Per Rev
The length of the drag chain per turn of the drag shaft.
To figure the drag chain length, you can either:
ll Multiply the diameter of the drag shaft by 3.14.
l Mark the belt and measure the distance the mark
moved after one revolution of the drag shaft.
If these numbers are not correct, you will have issues
calibrating the spreader. If any of these settings physically
change in the implement, they need to be adjusted in the
FM-1000 integrated display to maintain accuracy.
