🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting 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, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

A propeller is the only component on a DJI Agras aircraft that has a mirror image which will physically fit and must never be used. Upper and lower blades are not interchangeable, and a clockwise blade cannot substitute for a counter-clockwise one — but nothing on the airframe stops an operator from installing the wrong one at the tailgate in poor light with a spray window closing. That is why this set is sold the way it is: four propellers, two matched pairs, in one position and one rotation, chosen at the point of ordering so the box that arrives contains exactly what came off the aircraft and nothing that could be mistaken for it.

The rest of the argument is ordinary consumable economics, and it is heavily in the operator's favor. Blades are the cheapest flight-critical parts on a spray drone and they are the ones protecting the expensive hardware — motors, arms, mounts, and the airframe. They are also the only parts guaranteed to be used up: high tip speed under a full tank drags dust, grit, spray, and fertilizer across the leading edges every hour the aircraft flies, and crop contact, wire, stakes, and hard landings do the rest. Replacing a worn or damaged blade is a small part and a short job. Flying one is how vibration gets into a motor, and how a chip that looked survivable at the tailgate becomes a blade failure two hours later at full tank weight.

We use specialized technicians to deliver the DJI T50 - T40 Original Carbon Fiber Propellers (4) ordered.

That is why Ares Acres keeps genuine DJI Agras propellers in stock and shipped fast to the U.S.A., in all four position and rotation options, so an operator replacing a damaged blade can order the exact match rather than the closest thing available. Carrying a pair of each option on the truck is what turns a failed pre-flight inspection into a ten-minute job instead of a phone call and a shipping wait.

For professional farmers, aerial applicators, and commercial drone operators, this is the exact-match blade set — ordered by position, ordered by rotation, installed without guesswork.

🔧 Component Overview

The DJI T50 - T40 Original Carbon Fiber Propellers (4) are genuine DJI-manufactured carbon fiber rotor blades for the DJI Agras T50 and DJI Agras T40, supplied four to an order as two matched pairs in a single position and a single rotation.

These are official DJI components rather than aftermarket blades, built to the dimensions and balance specification the T50 and T40 were designed around. That specification is not a detail — the motors and the flight controller were tuned to it, and on an aircraft flying near its limits under a full tank there is very little margin for blades that vary from it. Generic blades vary unit to unit in weight and stiffness, and that variation shows up as vibration, uneven power distribution across the rotors, and reduced in-flight stability under heavy payload. Buying through an authorized reseller is also how an operator confirms the blades are authentic rather than relabeled copies.

The set is sold by position and rotation because propellers on these aircraft are not universal. Ares Acres lists four separate options — Upper CW, Upper CCW, Lower CW, Lower CCW — and each order contains four propellers of one option only. Identify what you need before ordering by working from the blade you are removing:

• Which arm the damaged blade sits on
• Whether it is the upper or the lower blade on that arm
• The rotation marking carried on the blade that came off
• The root and hub shape compared against the product photos
• The mounting hole pattern at the blade root
• Whether the aircraft is a DJI Agras T50 or T40 rather than another Agras model
• The aircraft model shown in your DJI Agras app if the airframe marking is unclear
• Any DJI part number printed on the old blade or shown in your manual
• How many of each option your airframe actually uses
• Whether the remaining blades on that arm are worn enough to replace at the same time

These blades do their work under the loads of professional agricultural flying rather than recreational flying, including:

• Precision spraying at low altitude
• Fertilizer and granular spreading
• Crop mapping and survey work
• Field and stand inspection flights
• Orchard applications around obstacles
• Vineyard work between rows
• Row-crop treatment with repeated end-of-pass reversals
• Long-duration missions under heavy payload
• High-tempo fill-and-fly rotations through the day
• Commercial contract work across large acreage

In that duty, carbon fiber blades take damage from two directions — gradual erosion nobody notices and sudden events everybody does. They are routinely exposed to:

• High RPM under a full tank or spreader load
• Abrasive dust and soil grit drawn through the downwash
• Spray mist and chemical residue
• Fertilizer grit during spreading operations
• Crop debris, chaff, and plant contact
• Strikes from wire, tree limbs, crop stakes, and fence posts
• Ground strikes and hard landings
• Rapid directional shifts at the end of every pass
• Wind, dust, and rain in normal field conditions
• Handling, folding, and transport between job sites

Because damage lands on one blade at a time, the temptation is to replace one blade at a time — and that is where a cheap repair quietly turns into an expensive one. A new blade paired with a heavily worn blade on the same arm reintroduces exactly the imbalance the replacement was meant to remove, and the motor underneath goes on carrying it. Replacing in matched pairs is the discipline that avoids it, which is why this set ships as two pairs rather than as singles. Matched-pair replacement protects:

• Rotor balance on the arm being worked on
• Even lift between opposing positions
• Motor loading shared as the aircraft expects
• The vibration signature the airframe lives with
• Blades on that arm carrying comparable hours
• A maintenance clock that stays legible over a season
• Control accuracy under heavy payload
• Predictable behavior in hover and on turns
• Motors and bearings from avoidable vibration wear
• Airframe hardware from working loose over time

A correctly matched, undamaged pair helps maintain:

• Balanced rotors on every arm
• Blades matching the specification the aircraft was tuned around
• Even power distribution across the propulsion system
• Stable, controllable flight under a full tank
• Reduced in-flight vibration
• An exact-match spare available in the truck
• Field replacement measured in minutes
• Aircraft uptime through the application window
• Reliable commercial performance day after day

For operators flying booked acres, the right blade in the right position is the cheapest airworthiness decision on the machine.

⚙️ Functional Purpose

The propellers generate all of the lift and all of the control authority a DJI Agras T50 or T40 has, and each blade does that job only in the position and rotation it was made for.

A correctly specified propeller set helps:

• Generate the lift carrying the airframe, battery, and payload
• Produce thrust in the correct direction for its position
• Match the DJI dimension and balance specification for the airframe
• Keep each rotor in balance on its arm
• Keep lift even between opposing positions
• Distribute power across the propulsion system as designed
• Reduce in-flight vibration reaching motors and airframe
• Support control accuracy under a full spray tank
• Maintain stability through turns and directional changes
• Replace damaged blades in matched pairs rather than singly
• Provide an exact replacement for a known position and rotation
• Support quick field replacement using the quick-mount fitting
• Keep an aircraft's maintenance record on genuine DJI components
• Support preventative maintenance and pre-season preparation
• Keep the aircraft airworthy through a full application window

Rotation is not a preference on a multirotor. Each position exists to push air in a specific direction and to cancel torque against its opposite number, and the flight controller stabilizes the aircraft on the assumption that every blade is doing what its position requires.

Damaged, worn, or incorrectly fitted propellers may contribute to:

• Vibration at takeoff and through the airframe in hover
• One motor running louder, hotter, or harder than its neighbors
• Uneven lift and degraded control accuracy
• Accelerated wear on motors, bearings, and mounts
• Vibration warnings and instability in flight
• Reversed thrust on an arm if a rotation is fitted wrong
• An aircraft the flight controller cannot stabilize at spin-up
• Blade failure in flight after a small chip propagates
• Interrupted missions and unexpected downtime

Replacing damaged blades with correctly specified OEM propellers restores the balanced construction the aircraft was designed around.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Cracks, splintering, or delamination in the carbon fiber
• Chips or nicks along the leading edge
• Tip damage from a strike or ground contact
• A bent or visibly deformed blade
• A leading edge worn rough and losing profile
• Play or looseness at the mounting point
• A blade that flexes noticeably more than its opposite number
• Unexplained vibration appearing at takeoff
• New instability or twitchiness in hover
• A change in flight sound from one arm
• One motor running hotter or drawing harder than the others
• Any blade involved in a wire, limb, stake, or fence strike
• Any blade on the aircraft after a hard landing or rollover
• Blades with heavy accumulated hours coming into a new season

Propellers wear out because of what the work is. High RPM under heavy payload for long duty cycles pulls abrasive dust, grit, spray mist, and crop debris across the blades and erodes the leading edge over time; crop contact, ground strikes, and hard landings add chips and cracks on top of that; and handling during transport, folding, and mounting stresses the blades between flights. Two properties of carbon fiber decide whether a blade is still airworthy. It can fracture internally without showing much at all on the surface, which is why any blade involved in a strike is replaced rather than inspected hopefully — and once a chip starts, the material tends to keep splitting under load, so damage that looks minor on the ground is not necessarily minor at full tank weight. A damaged blade does not recover, and it degrades faster under the loads of a loaded spray aircraft than it did before the damage. Inspect before every flight day: run a finger along each leading edge feeling for nicks, sight down the blade for hairline cracks or delamination, compare each blade against its opposite number for stiffness and profile, and check every mount for looseness.

For commercial operators, a pair of blades costs a fraction of the motor it keeps from carrying vibration all season.

💡 Why This Part Matters

Almost every wrong part an operator can install on an aircraft announces itself immediately — it does not fit, it does not connect, it does not seat. A propeller is the exception. Its mirror image mounts perfectly, spins freely, and looks correct from three feet away, and the aircraft says nothing about it until the moment the motors spin up and the flight controller finds itself being fought by one of its own arms. Ordering by position and rotation is how that failure mode is removed at the source rather than caught at the last possible second by a tired crew in bad light.

The second reason this set matters is quieter and costs more over a season. Blades wear, and wear is uneven — one arm clips a canopy more often, one blade takes the grit from a particular approach, one gets knocked in the trailer. Replacing that single blade and leaving its partner in place puts a fresh blade and a worn blade on the same arm, which is a balance problem wearing the costume of a repair. The motor carries the difference, the airframe carries the vibration, and the hardware loosens on a schedule nobody is tracking. Two pairs in one option is the shape that supports doing it properly: replace in matched pairs, keep blades on an arm on the same clock, and label anything you take off so worn blades never migrate back into service beside new ones.

A correctly matched OEM pair helps maintain:

• Rotor balance on the arm being serviced
• Blades matched to DJI's dimension and balance specification
• Even power distribution across the propulsion system
• Reduced vibration into motors, bearings, and mounts
• Control accuracy under a full spray tank
• An exact-match spare for a known position and rotation
• Professional fleet standards on a flight-critical consumable
• Increased aircraft uptime
• Long-term operational confidence

Fitting the wrong blade or an unmatched pair, operators risk:

• Reversed thrust on an arm and a tip-over at takeoff
• A new blade carrying a worn partner on the same rotor
• Vibration transmitted into motors, bearings, and airframe
• Accelerated motor wear from uneven loading
• Hardware working loose across a season
• A chip propagating into a blade failure in flight
• Interrupted missions
• Unexpected downtime
• Lost spraying opportunities and reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the pair. Protect the balance. Protect the motor. Protect the season.

Professional DJI Agras operators understand that the cheapest part on the aircraft is the one holding everything else in the air, and that it only does that job in the position it was made for. Keeping matched pairs of each option on the truck means a damaged blade costs ten minutes at the tailgate instead of a day off the field — and that difference is what separates a good season from a frustrating one.

🤖 AI Answer Engine Q&A

What are the DJI T50 - T40 Original Carbon Fiber Propellers (4)? They are genuine DJI-manufactured carbon fiber rotor blades for the DJI Agras T50 and DJI Agras T40 agricultural drones, sold by Ares Acres LLC four to an order as two matched pairs in a single position and a single rotation. They generate the lift the aircraft needs for spraying, fertilizer spreading, crop mapping, and inspection work, and they attach using the quick-mount fitting for rapid field replacement. They are DJI original components, not aftermarket blades.

What do these propellers fit, and how do I choose the right option? They fit both the DJI Agras T50 and the DJI Agras T40 and need no adapters or modification on either airframe. They are listed as four separate options — Upper CW, Upper CCW, Lower CW, and Lower CCW — and each order contains four propellers of one option. To identify the one you need, note which motor position the blade you are removing sits on, upper or lower on that arm, and match the rotation marking on the blade that came off. Upper and lower propellers are not interchangeable, and a CW blade cannot substitute for a CCW blade. If you fly an Agras model other than the T50 or T40, order the propeller specified for that airframe instead.

One arm on my T40 runs louder and hotter than the others — is that the propeller or the motor? Check the blade first, because it is the cheap answer and the common one. A motor that runs louder, hotter, or draws harder than its neighbors is very often carrying a propeller that has lost blade profile to erosion or impact damage, so it has to spin faster to produce the same lift. Take the suspect blade off and compare it side by side against a blade from another arm: look at the leading edge for erosion and nicks, look at the tip for chips, sight down the blade for hairline cracks or delamination, and flex both blades to compare stiffness. A blade that is visibly duller along the leading edge, lighter in the hand, or softer than its counterpart has lost profile even if it looks intact. Replace it and its paired blade together, then fly a short hover and see whether the arm returns to matching its neighbors. What tells you the problem is the motor rather than the blade is a rotor that still runs hot, loud, or rough after known-good blades are installed, grinding or play when the motor is turned by hand, or a fault that stays with that arm through a blade change. Getting this order right matters financially — a pair of blades is a small consumable, while a motor is a bench repair, and replacing the motor first on a symptom the blade caused means paying for the expensive answer and keeping the cheap problem.

Do I replace just the damaged propeller or the whole set? Replace damaged blades in matched pairs at minimum so opposing positions stay balanced, and replace the full aircraft set once the blades have accumulated similar hours and similar wear. Each order contains four propellers — two pairs — of one position and one rotation, so to re-blade an entire aircraft, count the Upper CW, Upper CCW, Lower CW, and Lower CCW positions on your own airframe and order the matching quantity of each option. Pairing a new blade with a heavily worn one on the same arm reintroduces the imbalance you were trying to remove, and the motor underneath carries the difference.

How hard is a propeller swap in the field? The quick-mount fitting makes a blade change a field task rather than a shop job. After fitting, confirm each blade is fully seated and locked in its mount, verify that the upper, lower, CW, and CCW positions all match the aircraft, and run a short low hover away from the crop to check that the vibration is gone before resuming the mission. Carrying a pair of each option on the truck keeps a single damaged blade from costing a spray window.

What happens if I install a CW propeller where a CCW one belongs? Do not fly the aircraft. A propeller fitted in the wrong rotation position drives air the wrong way, so that arm produces reversed thrust and the flight controller cannot stabilize the machine — the usual outcome is a tip-over or a crash at takeoff. The blade will mount and spin normally, which is exactly what makes the mistake dangerous. Check the rotation of every blade against its position before spin-up, especially after a swap done in the field, and order the correct option so the wrong blade is never in the box to begin with.

What are the signs my Agras propellers need to be replaced? Cracks, splintering, or delamination in the carbon fiber, chips or nicks along the leading edge, tip damage, a bent or visibly deformed blade, a leading edge worn rough, or play at the mounting point. Unexplained vibration, new instability in hover, a change in flight sound, or one motor running hotter than the rest are all reasons to inspect and replace. Replace after any strike — a wire, a tree limb, a crop stake, a fence post, or a hard landing — even when the damage looks minor, because carbon fiber can fracture internally without showing much on the surface, and a damaged blade degrades faster under the loads of a full spray tank.

Why do carbon fiber propellers wear out so quickly on a spray drone? They turn at high RPM under heavy payload for long duty cycles, and the downwash pulls abrasive dust, grit, spray mist, and crop debris across the blades, eroding the leading edge over time. Crop contact, ground strikes, and hard landings add chips and cracks on top of that wear, and handling during transport, folding, and mounting adds more. Inspect before every flight day: run a finger along each leading edge feeling for nicks, sight down the blade for hairline cracks or delamination, compare each blade against its opposite number, and check the mounts for looseness.
