Air Tractor vs Cessna: At a Glance

• The Air Tractor AT-802A carries an 800-gallon hopper and 9,249 lbs of useful load — nearly four times the capacity of the Cessna AgTruck’s 200-gallon hopper.
• The AT-802A is powered by a Pratt & Whitney PT6A-65AG turboprop producing 1,295 SHP, while Cessna’s ag aircraft relied on piston engines in the 285 HP range — a fundamental difference in power class.
• Air Tractor, Inc. is the world’s leading manufacturer of purpose-built agricultural aircraft, and their lineup is engineered specifically for high-production aerial application — not adapted from general aviation designs.
• Hopper capacity directly determines how many acres you cover per load, making the AT-802A a significantly more productive platform for large-scale operations.
• Cessna’s AgTruck and AgWagon remain in service across smaller operations, but production of Cessna ag aircraft has long since ended — a key factor when evaluating parts availability and long-term support.

When you need to move fast across thousands of acres, the aircraft you choose makes or breaks your season.

The Air Tractor AT-802A and Cessna’s agricultural aircraft sit in entirely different performance categories, and understanding exactly where those differences lie helps operators make smarter fleet decisions. Whether you’re evaluating a first ag plane purchase or scaling up an existing operation, the specs tell a clear story. Air Tractor, Inc. has built its reputation as the global leader in purpose-built agricultural aviation, and the numbers behind their flagship AT-802A back that up convincingly.

The AT-802A Outguns Every Single-Engine Ag Plane on the Market

The Air Tractor AT-802A is the world’s largest single-engine agricultural aircraft. That’s not marketing language — it’s a specification fact. With a maximum takeoff weight of 16,000 lbs (7,257 kg) and an empty weight with spray equipment of just 6,751 lbs (3,062 kg), the AT-802A generates a working load that no comparable single-engine platform can match.

Cessna’s ag aircraft, including the AgWagon and AgTruck, were competent machines for their era. But they were designed and produced by a general aviation manufacturer that adapted existing airframes for agricultural use. Air Tractor builds aircraft from the ground up for one purpose: aerial application. That distinction shapes every specification on the page.

Air Tractor vs Cessna: Engine Power and Performance

Engine choice is the single biggest performance driver in any agricultural aircraft, and the gap between these two platforms here is substantial. The AT-802A runs a turboprop while Cessna’s ag line relied on piston power — a fundamental difference in how these aircraft perform under load, in heat, and across long operational days.

Air Tractor AT-802A Engine: P&W PT6A-65AG at 1,295 SHP

The AT-802A is powered by the Pratt & Whitney PT6A-65AG turboprop engine, producing 1,295 shaft horsepower at 1,700 RPM. It drives a Hartzell HC-B5MP-3F/M11276NS five-blade propeller, engineered to convert that power into productive thrust at low altitudes and working speeds. Turboprop engines in agricultural aviation offer a decisive advantage in torque response and reliability over piston alternatives, particularly when operating fully loaded in high-temperature field conditions. For those interested in exploring further, consider learning about safe and reliable aircraft chartering.

Cessna AgTruck Engine: Continental Tiara 6-285 at 285 HP

The Cessna AgTruck was fitted with the Continental Tiara 6-285, a horizontally opposed piston engine producing 285 HP. For smaller field operations and lighter application rates, this engine was adequate. However, piston engines in ag aviation face real limitations: they lose power output in high-density altitude conditions, require more maintenance intervals, and simply cannot deliver the torque-on-demand that a turboprop like the PT6A-65AG produces at the moment you need it most — at full load, low altitude, pulling out of a run.

Cruise Speed and Working Speed Comparison

Speed in agricultural aviation is measured in two ways: how fast you transit to the field, and how efficiently you work over it. The AT-802A’s 1,295 SHP engine gives it a significant cruise speed advantage, enabling faster repositioning between loads and reducing total operational hours per job. The Cessna AgTruck, constrained by its 285 HP piston engine, operates at noticeably lower transit and working speeds — which compounds into fewer acres covered per day at scale. For those interested in learning more about aviation and aircraft performance, you might want to explore aircraft chartering options.

Rate of Climb and Takeoff Distance Head-to-Head

Rate of climb matters in agricultural aviation because you’re operating at low altitudes, often near obstacles like tree lines, power lines, and terrain features. The AT-802A’s turboprop power delivers a climb performance that the AgTruck’s piston engine cannot approach, particularly when the aircraft is loaded to maximum gross weight. In real field conditions, this difference directly affects safety margins and turnaround efficiency on short or obstacle-adjacent fields.

Payload and Hopper Capacity: Where the Gap Is Enormous

If engine power is the performance story, hopper capacity is the productivity story. And on this metric, the comparison between the AT-802A and Cessna’s ag aircraft isn’t close — it’s a 4-to-1 difference in single-load capacity that reshapes the economics of every job.

AT-802A Useful Load: 9,249 lbs With an 800-Gallon Hopper

The AT-802A carries a payload of 9,249 lbs (4,195 kg) with an 800-gallon hopper — the largest hopper capacity of any single-engine agricultural aircraft in production. That volume means fewer reload stops per field, less fuel burned on repositioning flights, and a single pilot covering ground that would otherwise require multiple smaller aircraft. Air Tractor engineered this capacity specifically to give operators the ability to do the work of several smaller planes with one aircraft and one pilot. For those interested in safe and reliable aircraft options, exploring Air Partner could be beneficial.

Cessna AgTruck Hopper Capacity: 200 Gallons

The Cessna AgTruck was equipped with a 200-gallon hopper, which was a reasonable capacity for the smaller-scale operations it was designed to serve. For operators working smaller fields or applying products at lower volume rates, the AgTruck performed its role. But at 200 gallons per load, you are making four reloads for every single load the AT-802A completes. Over an eight-hour operational day, that reload gap translates directly into lost productive hours and higher cost-per-acre numbers. For those interested in a deeper understanding of the aviation industry, safety compliance is a non-negotiable aspect worth exploring.

What a 4x Capacity Difference Means Per Day of Operation

The math here is straightforward but the operational impact is significant. If an AT-802A completes five full loads in a working day at 800 gallons each, that is 4,000 gallons applied. A Cessna AgTruck operating the same day would need twenty loads to match that output — twenty ferry flights back to the reload point, twenty pump cycles, and twenty additional takeoffs and landings. Each of those cycles burns time, fuel, and mechanical wear.

For large-scale row crop operations in corn, soybeans, or cotton, this capacity difference is often the deciding factor in aircraft selection. A single AT-802A can realistically replace two or three smaller piston-powered ag aircraft on the same job, which changes the entire cost structure of the operation. That is exactly the productivity model Air Tractor designed the AT-802A around.

Airframe and Design Philosophy

Beyond raw numbers, the design philosophy behind each aircraft reveals just as much about their real-world suitability for professional aerial application. How an airframe is conceived — and by whom — shapes everything from structural load limits to cockpit ergonomics under a full day of repetitive low-level work.

Air Tractor: Purpose-Built for High-Production Agriculture

Air Tractor, Inc. builds every aircraft in its lineup with a single operational context in mind: high-production agricultural aerial application. The AT-802A fuselage, wing design, and landing gear are all engineered around the demands of low-level, high-cycle ag flying. The cockpit layout prioritizes fast visibility and control accessibility during application runs. The airframe is built to handle the structural stresses of repeatedly carrying maximum gross weight loads across short, repetitive flight cycles — something general aviation airframes were simply never designed to do at this intensity.

Cessna AgWagon and AgTruck: Legacy Designs From a General Aviation Manufacturer

Cessna’s agricultural aircraft, including the AgWagon 188 and AgTruck, were adaptations of the Cessna 188 airframe — a platform that started life as a general aviation design and was modified for agricultural use. Cessna no longer manufactures these aircraft, which means the existing fleet is aging, parts availability is increasingly limited, and there is no factory support pipeline for operators who depend on these airframes. For smaller operations with lower annual hours and existing familiarity with the platform, they remain serviceable. For operators building or growing a professional ag aviation business, the support ecosystem simply is not there.

Stall Speed and Low-Level Handling

Stall speed and low-level handling characteristics are critical safety and performance factors in agricultural aviation. You are flying at treetop height, at low speeds, with a loaded aircraft, making sharp turns at field edges. The margin between efficient operation and a dangerous situation is directly tied to how the aircraft handles in this environment.

• Low stall speeds allow tighter, more controlled turns at field boundaries without losing lift.
• Predictable stall behavior gives the pilot warning and recovery time in low-altitude situations.
• Wing loading affects how the aircraft responds to gusty or turbulent conditions during application passes.
• Control authority at low speeds determines how precisely the pilot can maintain swath alignment over the crop.
• Structural integrity at gross weight ensures the airframe handles repeated pull-up maneuvers without fatigue issues developing prematurely.

These factors are not just performance metrics — they are the daily working conditions of every agricultural pilot. An aircraft that handles predictably and confidently at low speed and low altitude reduces pilot workload and increases the accuracy of every application pass.

The AT-802A’s large wing area and high-lift design give it favorable low-speed handling characteristics despite its significant gross weight. The aircraft was designed to be flown at maximum load close to the ground repeatedly, all day, every day of the season. That design intent is embedded in every aspect of its aerodynamic profile.

AT-802A Stall Speeds at Maximum Gross Weight

At its maximum gross weight of 16,000 lbs, the AT-802A is engineered to maintain controlled, predictable flight characteristics through the low-speed regime that ag pilots work in constantly. The combination of the PT6A-65AG’s immediate torque response and the aircraft’s high-lift wing design gives pilots the power and aerodynamic support to recover quickly from any low-speed deviation during a working pass — a critical safety margin when operating ten feet above a crop canopy.

Low-Level Maneuvering Demands in Crop Dusting Operations

Crop dusting and aerial application are among the most demanding low-level flight environments in aviation. Pilots execute hundreds of tight 180-degree turns per day at field boundaries, often with obstacle clearance measured in feet rather than hundreds of feet. The AT-802A’s power-to-weight ratio at working weights gives it a decisive edge in climb rate out of these turns, which directly reduces exposure time near obstacles and allows faster re-entry into the next application pass. The Cessna AgTruck, with its 285 HP piston engine and lighter but less powerful configuration, simply does not have the same energy reserves available at the bottom of a turn.

Operational Range and Fuel Capacity

Range matters in agricultural aviation because fields are rarely next to the airstrip, and ferry time is unproductive time. The AT-802A’s operational range of 610 miles at economy cruise means it can reposition across large geographic coverage areas without refueling stops, giving operators flexibility to take on contracts across a wider service radius. Combined with its 800-gallon hopper, the AT-802A is built to spend the maximum possible portion of its flight hours doing productive work over crops — not flying back and forth to a fuel truck. For those interested in understanding more about aviation safety, safety compliance is a crucial aspect to consider.

AT-802A Range: 610 Miles at Economy Cruise

The AT-802A delivers a range of 610 miles at economy cruise, giving operators genuine flexibility in how they deploy the aircraft across a working season. That range means a single aircraft can cover a large geographic service territory without being anchored to one reload base, and it opens the door to contract work across regional boundaries that smaller, shorter-range piston aircraft simply cannot reach efficiently.

AT-802A Operational Range Summary

🛩 Economy Cruise Range: 610 miles
🛩 Max Takeoff Weight: 16,000 lbs (7,257 kg)
🛩 Hopper Capacity: 800 gallons
🛩 Engine: P&W PT6A-65AG — 1,295 SHP
🛩 Propeller: Hartzell HC-B5MP-3F/M11276NS
🛩 Empty Weight (with spray equipment): 6,751 lbs (3,062 kg)
🛩 Useful Load: 9,249 lbs (4,195 kg)

Turboprop engines like the PT6A-65AG are also considerably more fuel-efficient per unit of work performed compared to piston engines operating at similar output demands. When you factor in the AT-802A’s capacity to carry four times the product per load, the fuel cost per acre applied drops significantly compared to operating a smaller piston-powered aircraft across the same acreage. The AT-802A burns more fuel per hour in absolute terms, but it covers dramatically more ground during that hour — and that is the number that actually matters to a professional operator’s bottom line.

For operators running seasonal contracts across large row crop regions — think the Mississippi Delta, the Texas Coastal Plains, or the Central Valley of California — the combination of 610-mile range and 800-gallon capacity means fewer logistical constraints, fewer support crew deployments, and more acres billed per day of operation. That operational efficiency is a direct revenue driver, not just a performance footnote. For those looking to enhance their skills, aerobatic pilot training can provide additional expertise in handling complex flying conditions.

Fuel Capacity Comparison and Cost Per Acre Implications

The Cessna AgTruck’s 285 HP piston engine operates at a fraction of the AT-802A’s power output, which means a fraction of the fuel burn per hour — but also a fraction of the productivity. When you calculate cost per acre applied rather than cost per hour flown, the AT-802A’s turboprop efficiency and high hopper capacity consistently produce lower operating costs at commercial application scales. For small operations covering a few hundred acres per season, the Cessna’s lower fuel burn may be locally relevant. For anyone working thousands of acres under tight application windows, the AT-802A’s economics are simply more favorable at scale.

Which Aircraft Fits Your Operation Best

The honest answer depends entirely on the scale and intensity of your operation. If you are managing large-scale commercial aerial application contracts — covering thousands of acres per season, working under tight weather and calendar windows, and needing to maximize acres-per-day — the Air Tractor AT-802A is in a completely different league from any Cessna ag aircraft. Its 800-gallon hopper, 9,249 lb useful load, 1,295 SHP turboprop, and 610-mile range are designed specifically for high-production professional operations. The Cessna AgTruck and AgWagon served their era well, but they are legacy piston platforms that are no longer in production, with an aging parts supply chain and performance ceilings that reflect their general aviation origins. For operators building or scaling a serious ag aviation business today, the AT-802A represents the standard against which all single-engine ag aircraft are measured.

Frequently Asked Questions

Here are direct answers to the most common questions operators ask when comparing Air Tractor and Cessna agricultural aircraft.

Is the Air Tractor AT-802A the Largest Single-Engine Ag Aircraft Available?

Yes. The Air Tractor AT-802A is the world’s largest single-engine agricultural aircraft currently in production. With a maximum takeoff weight of 16,000 lbs, an 800-gallon hopper, and a useful load of 9,249 lbs, no other single-engine ag aircraft in production matches its working capacity. Air Tractor, Inc. built the AT-802A specifically to fill this role as the flagship high-production platform in their agricultural lineup.

Is Cessna Still Manufacturing Agricultural Aircraft?

No. Cessna discontinued production of its agricultural aircraft line, including the AgWagon 188 and AgTruck, years ago. The existing fleet remains in service with various operators, but there is no new production, no factory support pipeline, and parts availability continues to diminish as the fleet ages. Key considerations for anyone still operating a Cessna ag aircraft include:

• Replacement parts increasingly sourced from used aircraft and third-party suppliers
• No manufacturer support or airframe updates available
• Aging airframes with potentially high cycle counts on structural components
• Continental Tiara engine parts availability becoming progressively more limited
• No factory-backed avionics or equipment upgrade pathways

For operators still flying Cessna ag aircraft, transition planning toward a purpose-built platform like the AT-802A or another current Air Tractor model is a practical long-term consideration, not just a performance upgrade discussion.

Cessna’s agricultural aircraft made real contributions to the industry during their production years. The 188 series introduced many pilots to aerial application and served smaller operations across North America and internationally. But the platform’s limitations — piston power, modest hopper capacity, and general aviation design origins — were always present, and without manufacturer support, those limitations compound over time.

The contrast with Air Tractor’s current position is significant. Air Tractor, Inc. is an active manufacturer, continuously refining its agricultural lineup and supporting operators with factory resources, dealer networks, and purpose-built parts supply chains.

What Engine Does the Air Tractor AT-802A Use?

The AT-802A is powered by the Pratt & Whitney PT6A-65AG turboprop engine, producing 1,295 shaft horsepower at 1,700 RPM. It is paired with a Hartzell HC-B5MP-3F/M11276NS five-blade propeller. The PT6A family of engines is one of the most proven turboprop platforms in aviation history, with a reliability record and parts support infrastructure that gives operators confidence in long-term operational dependability.

The PT6A-65AG variant is specifically calibrated for agricultural aerial application demands — low-altitude, high-torque, high-cycle operations across long working days in demanding environmental conditions. This is not a general aviation engine adapted for ag use; it is a platform matched to the specific stress profile of professional aerial application work.

How Does Hopper Capacity Affect Productivity in Aerial Application?

Hopper capacity is one of the most direct productivity multipliers in aerial application. Every reload cycle — the ferry flight back to the airstrip, the pump cycle, the takeoff, and the transit back to the field — is time and fuel spent not applying product. The larger the hopper, the more acres you cover before that cycle interrupts your work.

The AT-802A’s 800-gallon hopper means that at a typical application rate, a single load covers a substantial acreage block before requiring a return. At four times the capacity of a 200-gallon platform like the Cessna AgTruck, the AT-802A completes one reload cycle for every four that a smaller aircraft must complete to cover the same acreage. Over the course of a season, that difference accumulates into a significant productivity and revenue gap between the two platforms.

Can a Cessna AgTruck Handle the Same Jobs as an Air Tractor?

For small-scale operations covering limited acreage at lower application intensity, the Cessna AgTruck was capable of performing standard aerial application work within its operational envelope. It was never designed for, and cannot replicate, the high-production output of the AT-802A on large commercial contracts.

The Cessna AgTruck operates with a 285 HP piston engine, a 200-gallon hopper, and a maximum takeoff weight of approximately 4,400 lbs. Against the AT-802A’s 1,295 SHP turboprop, 800-gallon hopper, and 16,000 lb gross weight, the performance and productivity gap is not incremental — it is categorical. These are fundamentally different classes of aircraft designed for fundamentally different scales of operation.

That said, the right aircraft for any operation is determined by the actual demands of that operation. A small family farming operation covering a few hundred acres with modest annual flight hours has different requirements than a commercial aerial application company working across multiple states on large commodity crop contracts. The Cessna AgTruck was a legitimate tool for the former. The AT-802A is engineered for the latter — and for operators whose ambitions and contract volumes are growing, it represents the most capable single-engine platform available anywhere in production today. For those interested in expanding their aviation knowledge, exploring aircraft chartering can offer additional insights.
