The Yacaré armored tractor.

[Badner]

During the second World War,deprived from Lend-Lease equipment due to her policy of neutrality, the Argentine acquired over 100 tractors from private sources and modified them as armored artillery tractors. These were International H.35,wheeled tractors which according to a report of the U.S. Military Attaché in Buenos Aires, were fitted with tracks.

The Yacares were distributed to several artillery groups throughout the nation., for the 105 mm guns and howitzers (one would tow the barrel of the gun, and the other the gun carriage) well as some of the Oerlikon mod. 1938 20 mm L.70 light A.A. shown in that photo from MILITARIARG...I wouldn't put too much importance to that article from Zona Militar. It doesn't even give the Yacaré's specifications...

Other pics of the Yacaré. Note the 7,65 mm. Madsen light machines guns, obviously these were aviation models. A U.S. Military Attaché reports states "the cart beyond this vehicle gave it an agricultural look."

The Yacaré (South American Alligator)- On September 1943 the Argentine Ministry of War acquired 30 wheeled tractors from the Argentine branch of International Harvester Company (which imported and assembles these vehicles locally) and was instructed to hold another 110 more, which were intended as artillery prime movers. These tractors consisted of two separate types: the W.30, with a power rating of 24/30hp fitted with cast=steel wheels and the W9 model, which had a power rating of35/45 hp equipped with rubbwe tires. Due to the war-inspired shortage of rubber, these tractors were fitted with caterpillar threads and modified for their new role. A U.S. intelligence report dated 25 April 1944 states that the engines had been fitted with apparatus to increase speed, and that great maneuverability was achieved. One of these was publicly displayed at the 4 June 1944 exposition. They were fitted with a pair of Madsen 7,65 mm machine guns. This photo illustrates some of the YacarΘs exhibited during the 9 July 199 parade.

A drawing of the Yacaré. Though the source erroneously refers to the armament as Madsen 11,35 mm machine guns, these were aviation weapons and employed by such types as the Curtiss Hawk 750, the Northrop 8A-2 and Martin 139AAs of he Argentine Air Corps. The armament carried by the Yacarés, as we have seen were aviation-type Madsens 7,65 without a shoulder stock.
