The auger is what meters product out of the hopper — the spinner disk only throws what the auger feeds it. When the auger motor is weak, the whole spreading job goes wrong quietly: the pattern still looks fine from the truck, but the rate is off and the field tells on you three weeks later. Cover crop windows, fall fertilizer, feed drops — none of them wait while you source a motor.

🔧 Component Overview

The DJI Agras T100 OEM Auger Motor is the drive unit behind the spreading system's metering stage. Where the spinner disk controls how far and how wide material is thrown, the auger controls how much material leaves the hopper and how steadily it arrives at the disk. Application rate accuracy lives and dies on this motor.

Mounted at the base of the spreading hopper, the auger motor turns the feed auger at a commanded speed that the aircraft's spreading controller adjusts in real time against ground speed, prescribed rate, and remaining load. That closed-loop relationship is why a tired auger motor is so deceptive — the aircraft keeps asking for more, the motor keeps falling short, and the operator sees a normal-looking spread pattern at an abnormal rate.

This motor is used across the full range of dry-material work:

• Granular fertilizer and dry blends
• Cover crop seed
• Rice and broadcast seed
• Feed products
• Soil amendments and lime-type materials
• Biological and specialty granular products
• Granular pesticides

The OEM Auger Motor helps support:

• Metering accuracy and rate control
• Steady, uninterrupted material feed
• Consistent spread density across the swath
• Prescription and variable-rate execution
• Spreading-system reliability under load
• Hopper emptying without bridging or surging
• Fleet productivity and mission completion
• Long-term spreading-system durability

Spreading duty is the hardest environment on the airframe. Through normal operation the auger motor sees:

• Continuous high-torque duty under a loaded hopper
• Abrasive granular product at the drive end
• Corrosive fertilizer salts and dust
• Moisture, humidity, and washdown exposure
• Vibration from flight and from the spinner assembly
• Frequent start-stop and rate-change cycles
• Wide ambient temperature swings
• Daily commercial deployment through peak season

Built to DJI OEM specification, this assembly is engineered to integrate cleanly with the aircraft's spreading architecture and hold commanded metering rates through demanding commercial workloads.

⚙️ Functional Purpose

The OEM Auger Motor provides the torque that moves product out of the hopper at a controlled rate. It helps:

• Drive the feed auger at commanded speed
• Hold application rate under a full, heavy hopper
• Deliver a steady material stream to the spinner disk
• Support variable-rate and prescription spreading
• Prevent surging, starving, and rate drift
• Maintain even spread density across the pass
• Support accurate product accounting per acre
• Reduce spreading-system fault codes and aborts
• Keep the hopper emptying cleanly to the last load
• Protect downstream spreading components
• Maintain fleet readiness during application windows
• Reduce unplanned downtime and repair cost

A weak or failing auger motor commonly produces:

• Under-application without an obvious pattern problem
• Rate that falls off as the hopper load increases
• Surging or pulsing material flow
• Spreading-rate warnings and system faults
• Product left in the hopper at end of mission
• Longer mission times and wasted flight hours
• Re-treatment costs and unhappy customers

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Auger not turning or turning intermittently
• Application rate consistently below commanded rate
• Rate that sags as hopper weight increases
• Surging, pulsing, or inconsistent material feed
• Spreading-system fault codes or rate warnings
• Motor stalling under load
• Abnormal noise, growl, or whine from the drive end
• Motor running hot after a normal load
• Excessive vibration at the hopper base
• Electrical faults or intermittent motor power
• Fertilizer corrosion at the motor housing or hardware
• Product left in the hopper at the end of a mission
• Findings from scheduled maintenance inspection
• High-hour fleet refurbishment and preventative programs

Field diagnostic: before condemning the motor, clear the mechanical causes — a worn or rounded auger, a failed auger bushing, caked or bridged product in the hopper throat, or a foreign object jammed in the flight. Those account for most rate complaints and they are cheap. Then test under real conditions, not on the bench: this motor can spin freely with an empty hopper and still fall behind under a full one, so weigh a known load, run a measured test strip, and compare product actually applied against the rate the controller reported. A consistent shortfall that scales with hopper weight is a torque problem, which is the motor. Turn the auger by hand with power off and feel for roughness, drag, or lumpy resistance at the drive end. Corrosion at the motor housing is a terminal finding — fertilizer salt wicks in and a corroded motor does not come back. Wash and dry the spreading assembly at the end of every spreading day; nothing extends the life of this component more than not letting product sit on it overnight.

What actually kills these motors:

• Fertilizer salt corrosion at the housing, shaft, and mounting hardware
• Sustained high-torque duty under heavy granular loads
• Abrasive dust and product migrating into bearings and seals
• Running the auger against a jam or bridged hopper instead of clearing it
• Moisture and washdown intrusion with product residue present
• Vibration transmitted from a worn auger, bushing, or unbalanced disc
• Heat buildup on long spreading days in high ambient temperatures

Post-install checklist:

• Work with the aircraft powered down and the battery removed
• Inspect the auger, bushing, and hopper throat while the system is open — replace worn wear parts together
• Seat the motor square and torque mounting hardware to specification
• Confirm the electrical connector is fully seated and the harness is routed clear and secured
• Turn the auger by hand and confirm it rotates freely with no binding
• Run the spreader empty and listen for smooth, even operation at multiple rates
• Perform a rate calibration before the first paid load
• Weigh a known load and fly a test strip; confirm applied product matches reported rate
• Check spread density across the swath, not just spread width
• Wash and dry the spreading assembly at the end of every spreading day
• Log the install and track hours so the next replacement is planned, not emergency

💡 Why This Part Matters

Spreading revenue is measured in accuracy, not just acres. A customer pays for a rate, and the auger motor is the component that delivers it. The spinner disk gets the credit for a good pattern, but if the auger is not metering steadily, a perfect pattern is just an evenly wrong application.

The OEM Auger Motor helps maintain:

• Commanded application rates under full load
• Steady, surge-free material feed
• Accurate prescription and variable-rate execution
• Consistent coverage density across the field
• Clean hopper emptying and honest product accounting
• Fewer aborted missions and fault codes
• Longer life for downstream spreading components
• Maximum aircraft uptime through peak season

Without a healthy auger motor, operators risk under-application, re-treatment costs, missed application windows, damaged customer trust, and a hopper full of product that never made it to the ground.

Meter the product. Hold the rate. Empty the hopper. Spread it right.
