Transavia Airtruk & Skyfarmer Agricultural aircraft:

The Transavia PL-12 Airtruk is a single-engine agricultural aircraft
designed and built by the Transavia Corporation in Australia. The
Airtruk is a shoulder-wing strut braced sesquiplane of all-metal
construction, with the cockpit mounted above a tractor engine and
short pod fuselage with rear door. The engine cowling, rear fuselage
and top decking are of fibreglass. It has a tricycle undercarriage,
the main units of which are carried on stub wings. It has twin tail
booms with two unconnected tails. Its first flight was in 22 April
1965, and was certified on 10 February 1966.

Design and development:
It was developed from the Bennett Airtruck designed in New Zealand by
Luigi Pellarini. It has a 1 metric ton capacity hopper and is able to
ferry two passengers as a topdresser. Other versions can be used as
cargo, ambulance or aerial survey aircraft, and carry one passenger in
the top deck and four in the lower deck.
The Airtruk is also sometimes known as the Airtruck. Because the name
"Airtruck" was registered by the New Zealand companies Bennett
Aviation Ltd and Waitomo Aircraft Ltd, for their PL-11, Transavia
found another name for their PL-12 ("Airtruk").
July 1978 saw the first flight of an improved model, the T-300
Skyfarmer, which was powered by a Textron Lycoming IO-540-engine. This
was followed in 1981 by the T-300A with improved aerodynamics
