G-164 Ag Cat

From initial production through 1981, Schweizer built 2,455 aircraft under contract. In 1981 Schweizer bought the rights to the design and continued production under the name Schweizer Ag-Cat.Schweizer sold the design to Ag-Cat Corp. of Malden, Missouri in 1995.

G-164 Ag Cat

The Grumman G-164 Ag Cat is a single-engine biplane agricultural aircraft, developed by Grumman in the 1950s.

The Ag Cat was the first aircraft specifically designed by a major aircraft company for agricultural aviation,[2] and the first aircraft designed according to the regulations of Civil Aeronautics Manual Part 8, which had been written especially for agricultural aircraft.

In 1955, Grumman preliminary design engineers Joe Lippert and Arthur Koch proposed the design for a “purpose built” crop dusting airplane as a means of fulfilling a pressing need in the agricultural community as well as the perceived need for Grumman to diversify its product lines. The initial market survey indicated that 100 – 200 of this type could be sold each year. Lippert’s initial proposal was made under the project name “Farmair 1000.”


The first G-164, which was built by Grumman (N74054), was equipped with a Continental W670 Series 6A-16 powerplant. This ship accomplished its maiden flight on May 27, 1957, with Grumman test pilot Hank Kurt at the controls.[2][3] This initial flight test consisted of three short familiarization hops with the take-off weight set at 3122 lbs and the centre of gravity at 31.2%. Flight tests 2 & 3, with test pilot Victor Eble, were accomplished on May 28, 1958, to evaluate the general flight characteristics. A total of 46 test flights were completed by the end of August 1958 with a general finding that this was a well-behaved aircraft with only minor refinements needed before production.

When the decision was made to authorize production, Leroy Grumman suggested marketing the aircraft under the name “The Grasshopper”; however, Dick Reade suggested “Ag-Cat” following Grumman’s naming tradition using the suffix “-Cat” in aircraft names (e.g., F4F Wildcat and F6F Hellcat). Mr. Grumman agreed and the Grumman G-164 became the “Ag-Cat.” 



Ag Cat
The basic model Ag Cat was certified with four different engines: the 220-225 hp (164-168 kW) Continental Motors radial engine, the 240 hp (179 kW) Gulf Coast W-670-240 radial engine, the 245 hp (183 kW) Jacobs L-4M or L-4MB radial engine and the 275-300 hp (205-224 kW) Jacobs R-755 radial engine. A total of 400 of this model were produced.[6]
Super Ag Cat A/450
The G-164A became the main model starting with serial number 401. This model featured a 450 hp (335 kW) Pratt & Whitney R-985 radial engine along with a higher gross weight, increased fuel capacity, larger diameter wheels and improved brakes.[6]
Super Ag Cat A/600
The A/600 incorporated the same improvements embodied in the A/400, but was powered by a Pratt & Whitney R-1340 radial engine of 600 hp (450 kW).

Grumman Ag Cat (1957)

In February 2001, the design was sold to Allied Ag-Cat Productions Inc. of Walnut Ridge, Arkansas. Allied Ag-Cat are not producing new aircraft, although a related company operates a large fleet of Ag-Cats.

The basic airframe incorporates many safety innovations, including a pressurized cockpit to keep pesticides out, air conditioning and a fuselage structure that is designed to progressively collapse in the event of a collision.[4] Lippert and Koch were recognized for their innovation in agricultural aircraft, being awarded the Puffer Award by Delta Air Lines in 1974.

Floats were approved for the aircraft in the early 1990s in Australia
