Introduction
The example refers to a solid fertilizer spreader mounted on a tractor.

contained in the hopper, the tractor - spreader
unit can become unstable. In order to check the
total stability, the following relation can be applied to calculate the minimum ballasting at the front IF, min ,

The calculation takes into account the rear mounted equipment and the front - rear combinations.
