The TL.37 was an Italian military artillery tractor of World War II. It was manufactured by SPA (Società Piemontese Automobili), an Italian car maker that was a subsidiary of Fiat.

Development and history

Several, self-propelled gun variant TL.37's

While the Pavesi P4/100 artillery tractor was popular and was produced in large numbers, it was considered bulky and the suspension inadequate for rough terrain and Spanish roads. A request by the Royal Italian Army was placed in 1935 for a new artillery tractor with the specifications that it have four-wheel drive, accept either solid rubber or inflatable tires, a crew of six, be able to climb a 60 degree slope, and have the capacity to tow up to 100mm artillery pieces at 40 km/h across rough terrain. Fiat-S.P.A. met this call with the TLa (Trattore Leggero per artiglieria). In 1937 the TLa competed against a design from Breda Meccanica Bresciana and won, so was adopted and renamed the TL.37 with production beginning in October 1937. 24 units were sent to Libya for extended testing in 1938, towing Cannone da 75/27 modello 06 guns and 100-round ammunition trailers, where performance was found to be satisfactory. On 1 March, 1942, 1,021 tractors were in service with 1,021 on order. By 30 April, 1943, 2,267 were in service with a further 479 on order. In 1941 captured units were evaluated by n troops, who considered the TL.37 as the best artillery tractor being used in North Africa.

Hungary purchased an unknown quantity of TL.37s, and after the Italian Armistice in 1943 they continued to be used by German forces as well as the Italian Social Republic. Post–war, it was in service until 1948 with the Italian Navy.

A self-propelled gun variant was also built, with a Cannone da 75/27 modello 11 fitted at the rear. The TL.37 was also the basis for a general–purpose truck, the Fiat–SPA AS.37, and two armoured cars the Fiat–SPA S37 (Fiat-SPA Autoprotetto S37) and the Fiat-SPA AS43.
