The Piper AG Planes - Agricultural Aircraft (1978)
THE PIPER AG PLANES : More airplane for the dollar.
The Piper Ag Planes --
300 hp Brave and 235 hp Pawnee D
These aircraft represent more than 30 years of Piper experience in the design, manufacture and constant refinement of agricultural aircraft.
Piper pioneered the design which has become the universally accepted standard for modern ag planes. Considerations include:
- Low wing configuration for broad swath and a good downwash for proper penetration of chemicals.
- High, rear-mounted cockpit with long fuselage structure ahead for pilot protection and excellent visibility.
- Precise, reliable dispersal equipment for liquid and dry materials.
- Strong, tough, corrosion-treated and easily maintained airframes designed for quick routine cleaning and maintenance.
- Choice of airframes and 1200 hr TBO Lycoming powerplants to meet a variety of application requirements.
- Exceptional handling ease with lively responsiveness essential to ag operators.
And the Piper ag models still do the job better… more cost effectively… than any other ag planes on the market. More Airplane For The Dollar.
The Brave 300 and the Pawnee D incorporate more pilot comfort features than any other ag planes on the market.
Superb visibility, ram-air "pressure" cockpit, well placed controls, absence of cockpit clutter, professionally planned and padded instrument panel, excellent heating and ventilation, wide seat contoured for back support -- these are some of the provisions that are standard in the elevated cockpit.
Constant speed two blade propeller with spinner is standard and a constant speed three bladed propeller is also available.
Piper agricultural aircraft have been in continuous production longer than any other ag aircraft. More than 5500 have been manufactured since 1959, during which time continuous improving and updating has taken place.
In more than 80 countries around the world, Pipers are engaged in precisely controlled seeding, fertilizing and application of solid and liquid chemicals.
They are involved every step of the way in improving, fertilizing, and seeding crops -- controlling insect pests at their various stages of development, brush and weed control, plant disease control and application of pre-harvest chemicals.
Ag aircraft advantages over ground equipment include:
- Better fuel efficiency, as low as 1/20 gallon per acre
- Faster crop coverage, with effective dispersal of solids and liquids; 6/7 acres per minute
- Capability to work when ground equipment cannot due to maturity and size of crops or wet soil conditions
- Thorough coverage without hazard of knocking down crops or compacting soil
- Safety of the carefully controlled and filtered cockpit environment
- Cost effectiveness of intensively used contracted aerial application equipment permitting farmers to minimize or completely eliminate costly ground application equipment.
Agricultural operators, pilots and their customers all benefit from the performance, precision, protection and operating economies built into the Piper models.
Brave 300 -- New and Powerful
The Brave 300 is especially designed for the operator who needs the extra performance provided by a rugged, reliable 300 hp engine with a money saving 1200 hr. TBO.
The powerplant is the Lycoming 6 cylinder, dual ignition engine with Bendix fuel injection and constant speed propeller.
This proven engine, used for many years in a variety of Pipers including the retractable Lance and the load-hauling Cherokee Six, is legendary for reliability and trouble-free operation far from maintenance bases.
In the Brave 300 it provides added performance to the ag operator faced with large acreage to cover and with demanding conditions of terrain and altitude.
You have a choice of 30 and 38 cu. ft. hoppers (225 and 275 gallons), and of quick-change spray systems in high, medium and low volume, plus an all-purpose spreader for solids in your choice of stainless steel or aluminum.
All purpose streamlined spreader, in stainless steel or aluminum, applies dry chemicals at rates from 5 to 200 lbs. per acre.
Brave's powerplant, the world-proved 300 hp Lycoming, is instantly accessible. Cowl is easily removed and spark plugs, oil filter, and air cleaner are all readily accessible.
All controls for power and dispersal equipment are carefully arranged on the left side of the cockpit for easy operation by the pilot. Electric spray valve with control stick switch is available.
Brave's super long range fuel cells-87 usable gallons total -- are standard, and mounted in wing roots and linked to a header tank to operate as a single fuel supply. Tanks are filled with polyurethane safety foam which acts as an infinite baffle and provides maximum slosh suppression.
In the Brave's instrument panel, upper and lower instruments are separated by a large protective roll. Essential instruments -- air speed, spray pressure gauge, tach and manifold pressure gauge -- are in pilot's line of sight as he concentrates attention outside airplane.

Pawnee D 235 - Tractor of the Sky
Piper's popular Pawnee D is powered by a ruggedized 235 hp low-compression Lycoming engine with 6 cylinders and dual ignition.
The fiberglass multi-purpose hopper has a capacity of 150 gallons of liquids or 1200 lbs. of solids. A variety of high and low volume spray systems are offered, in addition to an aluminum spreader.
The nimble Pawnee D is unsurpassed in the ability to disperse chemicals for fields close-in and with small-to-medium acreage- with exceptional economy and efficiency.
The Lycoming engine's 1200 hr. TBO and proven reliability with ease of maintenance are important operators' benefits, too.

Brave 300 -- strongly built, pilot-protective, corrosion-proofed, easy to maintain and repair.
- Quick-change spray system, with high, medium and low volume versions, can apply liquid chemicals at rates up to 19 gallons per acre in variable swath width to 80 feet. Booms mounted aft of wing minimize drag and are in full view of pilot.
- Landing and taxi lights, anti-collision wingtip strobes, navigation and instrument lights are all available in the Brave.
- Aerodynamically clean, full cantilever wing, a carry-through structure that does not interfere with hopper design, features high strength main spar attachment, laminated spar construction and energy-absorbing leading edges and tips.
- Landing gear is rugged and simplified. Large 8:50 x 10 tires and 10" Scott Tailwheel facilitate operations from rough or soft fields. Hydraulic disk brakes (toe operated) are easily and quickly serviced.
- Wire deflector in front of windshield is supplemented by a heavy steel cable which runs back to rudder tip to deflect utility wires. Main landing gears are also fitted with wire cutters.
- Raised cockpit is 38" wide allowing for maximum pilot comfort. Seat is well contoured with lumbar support and ventilation. Seat and canted rudder pedals are adjustable.
- Full shoulder harness with inertia reel permits unrestricted freedom of movement.
- Sealed cockpit area uses filtered "ram air" with positive cockpit pressure to provide excellent ventilation.
- High-mounted cockpit, sloping nose, pageWrapper-around rear window and overhead window give pilot "super" vision. Doors on both sides have quick-release hinges for fast emergency exit.
- Solid one-piece heavy duty cockpit floor is sealed and uncluttered.
- An optional high-volume heater in sealed cockpit area eliminates need for cumbersome clothing on chilly mornings.
- Reinforced fiberglass hopper is available in 30 and 38 cu. ft. versions. Large top hatch expedites loading of solids, and liquids can be loaded through the hatch or the optional side loader.
- Plastic loading door is unpainted and hopper is translucent so pilot sees contents. Exterior sight gauge has been added for convenience during ground loading of liquids. Clear glass window in back of hopper aids pilot in monitoring contents.
