🇺🇸 U.S.A. FIRST
Ares Acres proudly supports American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.
FREE & FAST shipping is included for all U.S. customers.
We understand that every day of downtime can impact productivity, scheduling, profitability, and customer commitments. When a spinner disk wears out during spraying season, the cost is not simply the replacement part—it is inconsistent droplet size, uneven coverage, wasted chemical, lost field time, delayed applications, missed weather windows, and reduced operational confidence.
That is why Ares Acres focuses on fast fulfillment, responsive support, reliable sourcing, and practical replacement components that help American drone operators keep their aircraft working when it matters most.
For farmers, applicators, service providers, repair technicians, and commercial drone operators, precision-balanced spinner disks are essential for maintaining uniform, efficient, field-ready spray performance.

🔧 Component Overview
The DJI Agras T40 Centrifugal Sprinkler Spinner Disk is the official OEM replacement for the upper or lower rotating disk that drives uniform chemical and fertilizer dispersion.
These precision-balanced components maintain consistent droplet size and spray distribution, critical for high-volume agricultural applications.
When a spinner disk is worn or damaged, spray patterns can become inconsistent, reducing coverage and wasting product. Replacing only the upper or lower disk with this genuine DJI part restores full spraying performance and minimizes downtime.
Key features include:
- Genuine DJI OEM part – factory-certified for Agras T40 drones
- Position-specific options – Upper or Lower centrifugal spinner disk
- Optimized atomization – maintains consistent droplet size for uniform coverage
- Durable construction – resistant to chemicals, corrosion, and heavy-duty field conditions
- Cost-effective repair – replace a single disk instead of the full sprinkler assembly
Spinner disks live in the most demanding zone of the spray system—spinning at high speed in constant chemical contact. During commercial use, they may be exposed to:
- Continuous high-RPM rotation
- Constant chemical contact
- Herbicide, fungicide, and insecticide formulations
- Liquid fertilizer exposure
- Abrasive particles and sediment
- Flight vibration
- Repeated cleaning cycles
- UV exposure
- Temperature changes
- High-hour daily deployment
Over time, these conditions gradually erode the disk's precision surfaces—and because atomization quality degrades slowly, many operators don't notice until coverage problems show up in the crop.
⚙️ Functional Purpose
The original Centrifugal Sprinkler Spinner Disk is designed to atomize and evenly disperse spray liquids from the DJI Agras T40 centrifugal sprinkler system.
The component helps:
- Atomize spray liquid into consistent droplets
- Maintain uniform spray distribution
- Support accurate droplet-size control
- Deliver even coverage at high flight speeds
- Support heavy-payload application work
- Reduce chemical waste from uneven patterns
- Preserve factory spray geometry
- Restore worn or damaged atomization surfaces
- Support professional spray-system maintenance
- Reduce preventable aircraft downtime
- Maintain commercial field readiness
The upper and lower disks work together as a matched atomization system. Wear on either one changes the spray pattern the whole system produces.
A worn or damaged spinner disk may contribute to:
- Inconsistent droplet size
- Uneven spray patterns
- Coverage gaps or streaking
- Excessive drift from over-fine droplets
- Wasted chemical
- Reduced treatment effectiveness
- Sprinkler vibration or noise
- Unexpected field interruptions
⚠️ Common Replacement Indicators
Replacement may be recommended when operators observe:
- Visible disk wear or surface erosion
- Cracked or chipped disk edges
- Warped or deformed disk
- Inconsistent spray pattern
- Droplet size drifting from expected settings
- Coverage streaking visible in treated fields
- Sprinkler vibration or unusual noise
- Chemical buildup that cannot be cleaned
- Chemical-related material degradation
- UV-related brittleness
- Impact damage
- Damage discovered during cleaning or inspection
- Spray system refurbishment
- Preventative seasonal replacement
- Long-term commercial wear
Common failure causes include abrasive erosion from sediment-bearing mixtures, chemical attack on the disk material, UV degradation, impact from debris, and simple high-hour rotational wear.
Because spinner disks are consumable wear items, many commercial operators replace them on a seasonal schedule rather than waiting for coverage problems to appear in the field—the disk is far cheaper than the wasted chemical and re-treatment costs of a bad pass.

💡 Why This Part Matters
Uniform droplet size and spray coverage are essential for effective crop treatment.
The upper and lower centrifugal spinner disks work together to deliver a consistent spray pattern at high flight speeds and heavy payloads.
Using authentic DJI parts ensures optimal atomization, structural integrity, and long-term reliability, protecting your investment and guaranteeing maximum yield efficiency.
Without properly functioning spinner disks, operators may risk:
- Uneven coverage and treatment gaps
- Inconsistent droplet size and drift
- Wasted chemical on every acre
- Reduced treatment effectiveness
- Re-treatment costs
- Sprinkler system wear
- Unexpected aircraft downtime
- Delayed field applications
- Missed weather windows
- Reduced operational confidence
For practical operators, the value is straightforward:
Balance the spin. Sharpen the pattern. Cover every acre. Keep the aircraft working.
Professional DJI Agras operators understand that spray quality is decided at the disk—the last component the chemical touches before it reaches the crop.
The DJI Agras T40 Original Centrifugal Sprinkler Spinner Disk provides the precision-balanced, position-specific atomization surface needed to restore factory spray performance, protect chemical efficiency, and maintain dependable commercial agricultural operation.
