FERTILIZER SPREADER
GEARBOX
MODEL LIST
Fertilizer Spreader Gearboxes transfer power from the tractor’s PTO to the spinner discs or agitators that distribute fertilizer, seed, or granules. The gearbox reduces PTO speed, increases torque, and ensures consistent spreading performance. Its durable, corrosion-resistant design withstands harsh fertilizer environments.
JENA supplies a wide range of fertilizer spreader gearboxes for various spreader types. With over 25 years of OEM/ODM experience, JENA provides reliable solutions for agricultural machinery manufacturers worldwide.

FERTILIZER SPREADER GEARBOX OVERVIEW
Functions
- Power transmission & speed control — A fertilizer spreader gearbox transfers PTO input power (typically 540 or 1000 RPM) to the spinner disc or agitator at a controlled output speed. The reduction ratio ensures even spreading patterns, stable disc rotation, and consistent fertilizer distribution across different field conditions.
- Durability & environmental protection — Gearboxes are commonly built with cast iron or alloy-steel housings and corrosion-resistant coatings to withstand long-term exposure to fertilizers—materials that can be highly abrasive and chemically corrosive. High-quality sealing systems prevent ingress of dust, granules, and moisture, protecting gears and bearings from premature wear.
- Load & contamination protection — Many spreader gearboxes incorporate overload safeguards or torque-limiting designs to prevent damage when the disc or agitator becomes jammed by clumps of fertilizer or foreign objects.
Typical Agricultural Applications
- Granular fertilizer spreading — Transfers torque to the spinner disc, ensuring uniform distribution of urea, NPK, potash, and other granular materials across wide working widths.
- Seed, salt, and lime distribution — High-ratio gearboxes support stable spreading of lighter materials like grass seed or heavier, denser products such as lime, commonly used in pasture maintenance or soil correction.
- Orchard & vineyard nutrient application — Compact gearbox designs fit low-clearance spreaders used between narrow rows in orchards and vineyards.
- Winter road maintenance — Some gearboxes are used in salt spreaders for de-icing operations due to their corrosion-resistant construction.
Key Design Features
- PTO interface & spline compatibility — Input shafts are designed to match standard tractor PTO splines and speeds. Correct PTO matching prevents vibration, misalignment, and excessive wear.
- Ratio configurations & output options — Available in multiple gear ratios to achieve precise spinner-disc RPMs. Output shafts may support different disc mounts, agitators, or twin-disc configurations depending on the spreader design.
- Corrosion-resistant construction — Because fertilizer is corrosive, gearboxes typically feature specialized coatings, sealed bearings, and high-durability gaskets to prevent chemical damage during extended operation.
- Agitator & disc drive integration — Some models incorporate dual-output designs for simultaneously driving an agitator (preventing material bridging) and the main spreading disc.
- Serviceability — Accessible fill, drain, and level plugs, along with breather vents and inspection points, make routine service easier in field conditions.
Short Maintenance & Inspection Checklist
- Monitor oil level and condition routinely—most fertilizer spreader gearboxes use 80W-90 or similar gear oil and require checks every 50 hours or as recommended.
- Inspect seals and output shaft areas frequently because fertilizer dust is abrasive and can accelerate seal wear.
- Check disc bolts, agitator mounts, and shaft keys before seasonal use or after heavy workloads.
- Verify overload components (where applicable), and inspect for damage after any blockage or jamming event.
- Confirm compatibility before ordering: PTO speed, spline type, shaft size, mounting pattern, and required gear ratio must match the spreader model.
