The photographer asked wiki contributor Johannes Maximilian for information about this truck and is grateful for the information provided:

• The grey tractor is a Pampa T01, mostly referred to as the Pampa, a legal Argentinian version of the Lanz Bulldog D1506, built in the 1950s under licence by Industrias Aeronáuticas y Mecánicas del Estado. It has a 10.3 litre Akroyd engine (hot bulb engine, two-stroke), producing either 55 or 60 PS. Increasing power output is really easy because these engines produce a ton of torque; it is very likely that the actual power output is much higher. The gearbox of the Pampa is a 3×2 speed gearbox, and it even has a reverse gear (early Lanz Bulldogs did not have a reverse gear because the two stroke engine does not have a fixed direction of rotation). I am sure that this Pampa was repainted, the original paint colour is orange.
