Centrifugal Twin Disc Spreaders
These systems utilize rotating discs with adjustable vanes to throw granules over wide areas. They offer high productivity and versatility for diverse granulated materials across varied working widths. Advantages include high speed and wide coverage. Limitations involve sensitivity to wind and granule quality, requiring frequent calibration to maintain pattern symmetry.
Pneumatic Boom Spreaders
These machines transport fertilizer via air streams through tubes to individual outlets along a boom. This ensures precise placement regardless of granule weight or weather conditions. Advantages include unmatched accuracy and reduced overlap. Limitations are higher mechanical complexity, increased maintenance requirements, and limited working widths compared to high-end disc systems.
Pendulum Spout Spreaders
A single oscillating spout moves side-to-side to distribute material. This legacy technology provides a simple, cost-effective solution for smaller farms or specialized horticultural applications. Advantages are simplicity and low cost. Limitations include narrow working widths and lower capacity, making them less suitable for large-scale modern broad-acre farming.
