  • Page 76: Product Setup Guidelines

    L3030G4 CNH Spread Pattern Header NOTE: SGN and Crush Strength together determine spread width. General Rules: A small product with low crush strength will have limited spread width capabilities. Spinner RPM must remain lower to keep from pulverizing the soft product, limiting your overall spread width. Additionally, a smaller product has less mass than that of a larger product, and in this case is another limiting factor for overall spread width.

  • Page 77: Crush Test

    Crushing strength can signifi cantly increase with particle size. 1. Figure 1 - Place individual granule on solid, smooth surface. 2. Place New Leader crush strength tester over granule, open end fl ush with surface. Ensure marker is next to handle.
