The Spreading System Reduction Gearbox for DJI Agras T50 (Part Number 00000354) is a high-precision mechanical component designed to act as the power transmission core between the electric motor and the seeder's rotating disc. This gear unit is fundamental for converting the motor's high rotation speed into controlled torque, ensuring that the dispersion of solids, seeds, and fertilizers occurs with absolute uniformity. At Magallan Aerospace Supply, we classify this item as a critical payload component , essential for the robustness of the T50 series spreading system.

Context and Importance in the Aerospace Sector

In the large-scale agricultural drone sector, the solid dispersal system faces severe mechanical challenges due to the weight of the inputs and the need for continuous operation under varying loads. The reduction gearbox is not just a transmission accessory; it is the component that protects the motor against mechanical overloads and ensures that the dispersal disc maintains the necessary angular velocity, regardless of the material density.

For aerial agricultural operations, the integrity of the Reduction Gearbox PN 00000354 is synonymous with operational availability. A failure in this unit immediately interrupts the UAV's seeding or fertilization capacity, generating logistical losses. Therefore, the use of an original DJI reduction gearbox, built to aerospace standards, is essential to prevent premature wear of the gear teeth and ensure mission efficiency.

What it is and how it works.

The PN 00000354 Reduction Gearbox is a modular assembly composed of high-strength helical or spur internal gears, mounted inside a sealed housing. Its primary function is to reduce the input speed (from the spreading system motor) to an output speed optimized for the spreading disc, significantly increasing the available torque.

In operational terms, when the pilot adjusts the dispersion rate on the radio control, the reduction gearbox ensures that the movement is smooth and without torque oscillations. The internal mechanism is factory-lubricated to withstand the high temperatures generated by friction during prolonged flights, maintaining the thermal and mechanical stability of the payload assembly.

Operational Applications in Drones

Seed Dispersal System

It works by ensuring that seeds of different sizes and weights are ejected with the correct centrifugal force, allowing for homogeneous soil coverage without mechanical damage to the seed embryos.

Application of Solid and Granulated Fertilizers

It can handle dense and abrasive materials. The reduction gearbox provides the necessary torque to rotate the disc even when the dispersion tank is at its maximum capacity (50kg in the case of the T50), overcoming the initial resistance of the material.

Dispersal of Baits and Soil Amendments

In pest control or soil amendment operations, the precision of mechanical reduction ensures that the programmed dosage per hectare is faithfully executed by the mechanical rotation of the system.

Technical and Operational Benefits

Operational Reliability: Robust construction that minimizes the risk of tooth breakage under stress, ensuring continuity of service in tight agricultural windows.

Torque Precision: Allows for refined control of the spray disc speed, essential for variable application rates.

Reduced Thermal Failure: Housing designed to dissipate heat generated by internal friction, protecting the seals and the adjacent motor.

Simplified Integration: DJI's original modular design allows for drop-in replacement without the need for complex manual adjustments or external calibrations.

Performance Optimization: Low energy loss due to friction, maximizing the autonomy of the drone's battery dedicated to the payload system.

Key Technical Differentiators

The key advantage of the Reduction Gearbox PN 00000354 is its particulate-proof sealing system . Operating under the solids tank, this part is constantly exposed to dust, corrosive fertilizer residue, and moisture. The original reduction gearbox housing features high-performance seals that prevent contaminants from entering the internal gears.

Furthermore, the materials used in the manufacture of the internal gears undergo specific heat treatments to increase surface hardness, which drastically reduces abrasion wear. This manufacturing standard ensures that the backlash between the gears remains within tolerance limits for much longer than in parallel replacement parts.

Compatibility and Installation Requirements

The reduction gearbox is exclusively compatible with the dispersion system of the DJI Agras T50 drone .

Installation requires partial disassembly of the seeder base unit. It is crucial to ensure that the mounting bolts are tightened to the torque specified by the manufacturer to avoid excessive vibration. We recommend checking the alignment of the output shaft with the dispersing disc before the first flight after maintenance.

Important Technical Guidelines and Considerations

Due to the abrasive nature of solid inputs, it is vital to clean the exterior of the gearbox after each operation. Fertilizer residue accumulated in the housing can cause external corrosion or compromise the rubber seals over time.

Signs of wear, such as excessive metallic noises or abnormal vibration in the dispersion system, indicate the need for immediate inspection of the gearbox. Never attempt to open the sealed gear housing unless you are an authorized technician, as loss of the original lubrication can cause catastrophic failure within minutes of use.
