Stability of the tractor-spreader unit (Appendix A EN 14017)
Introduction
The example refers to a solid fertilizer spreader mounted on a tractor.
Due to the machine's mass and products
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,
which enables obtaining a weight on the front axle equal to 20% of the tractor's tare:
The calculation takes into account the rear mounted equipment and the front-rear combinations.
