Grumman G-164 Ag-Cat

Ag-Cat B
The Grumman Aircraft Corporation designed the G-164 Ag-Cat in the middle of the l950s but only built two aircraft, the first, N74054 (#X1) being flown on 27 May 1957, as later that year Grumman contracted the Schweizer Aircraft Corporation of Elmira, in New York State, to build 100 aircraft. The first of these, N10200, was flown on 17 October 1958 and the Grumman G-164 Ag-Cat was certified by the FAA in the restricted category in January 1959. The engine for the prototypes and early production aircraft was the Continental W670-6N seven-cylinder radial of 220 hp. Because of its lighter weight than other engines, the longer engine mounts were cowled and gave the Ag-Cat a length of 24 feet and six inches. The wing-span was 35 ft8 in.
The first twenty-odd aircraft had flat fuselage side panels, rather than the more familiar ribbed panels. These early model aircraft were fitted with 215 US gallon hoppers.
The G-l 64 was also certified for the 220-225 hp Gulf Coast W670-240 (a modified Continental tank engine) and the 245 hp L4M or L4MB, 275-300 hp Jacobs R-755. Once with operators, some aircraft were converted to the 450 hp Pratt & Whitney R985 or the 600 hp R-1340, the latter readily recognised by extremely short engine mounts. Aircraft in the serial range 301-400 were built new with a 300 hp Jacobs R755 and an aluminium hopper of 245 US gallons installed. Nearly all of these aircraft were fitted with an enclosed canopy, which were also retrofitted to earlier aircraft.
Production of the G-164A Super Ag-Cat, with the P&W R-985 and a 300 US gallon fibreglass hopper, began in 1966 with number 401, N895X. The R-1340 engine was also fitted to these aircraft. Production of the G-164A ended at number 1730 with N6894Q.
In 1974 Grumman American announced a new model Ag-Cat. The wingspan had been increased from 36 feet to 42 feet 3 inches, but the hopper size remained at 300 US gallons and the new model was introduced with the 450 hp R-985 and, again, the R-1340 was later fitted. The recognition feature of the G-164B was the broad cord fin and rudder. With the R-985 installed the length of the G-164B is 25 feet, 7 inches. N88348 (#1B) was the first G-164B completed and over 800 were manufactured before production ended. The G-164B was certified under the A model banner.
In 1976 a stretched version, the G-164C, was flown and put into production. This was followed by the many turbine conversions.
Grumman American introduced in 1978 the Ag-Cat C duster, powered by a 600-hp Pratt & Whitney radial. It carries a 500-galIon hopper - the biggest dustbin available in any production agplane. In February 1976 the Super Ag-Cat C was flown, and in November 1977 was certificated; it has a deeper and longer fuselage accommodating a 500 US gallon hopper.
The factory PT6 turbine conversion kit weighing in some 230 kgs lighter, is around 10 to 12 knots faster and the PT6 power will enable a full load of 1500 litres to be carried for most operations. Fitted will be a three bladed Harztell prop, providing for a quieter operation and a reversing capability if ever required.
Although the Grumman Aircraft Engineering Company designed the Ag-Cat, built the two prototypes and marketed the type (subsequently through its subsidiary Grumman American Aviation Company), Schweizer Aircraft Corporation manufactured all the production Ag-Cats. Schweizer built 1400 aircraft between 1959 and 1975 and, with the exception of the engine fitted, the appearance of Grumman’s Ag-Cat hardly changed. In 1978 Gulfstream American bought Grumman American, and in 1979 a dual trainer Ag-Cat was shown at the Paris Air Show, although this was apparently designed and manufactured by some other company.
By 1979 Schweizer had produced 2,455 Ag-Cats at its Elmira, New York factory: 1,730 G-164As, 659 G-164Bs, 44 G-164Cs, and 22 G-164Ds - Super Ag-Cat Cs with a PT6A turbo-prop.
In 1981 Schweizer bought the Ag-Cat manufacturing and marketing rights from Gulfstream American, and produced an improved G-164B known as the Ag-Cat B-Plus and powered by either a 450-hp R-985 or a 600-hp R-1340 Pratt & Whitney nine-cylinder radial.

A Hershy FatCat modification widens the fuselage and raises the top wing some 8 inches.
Some have been powered by a Walter 601-F-II turbine engine delivering 750 hp using a five-bladed propeller, or the 600 hp Polish PZL 3S radial, and at least one has been equipped with two Lycoming TIO-540s, in separate Piper Seneca cowlings, mounted side-by-side, in the nose.
Ethiopian Airlines sc Company's Agro Aircraft Manufacturing division produced the Ag-Cat Corporation Ag-Cat G164B Turbine under the name Eshet for distribution and operation in Ethiopia and African countries except Algeria, South Africa, and Tunisia.
Admas Air Service in Ethiopia has produced over 10 Grumman Ag-Cats under licence from Schweitzer.
