The Holt tractors were a range of continuous track haulers built by the Holt Manufacturing Company, which was named after Benjamin Holt. Between 1908 and 1913, twenty-seven of the first 100 Holt caterpillar track-type tractors were used on the Los Angeles Aqueduct project, which provided a good proving ground for these machines.[1] Military UseThey were most famously used by the British, French and American armies in World War I for hauling heavy artillery: including BL 9.2-inch howitzers and the BL 8-inch howitzer.[2] Around 2000 Holt 75s along with 698 Holt 120s and 63 Holt 60s saw military use during the war.[2] Ironically both the Early designs of WW1 French Renault FT and German tanks A7V were based on Holt tractors. Specification{{Anchor|2 Ton|5 Ton|10 Ton}}There were at least three models used for military purposes: the Holt 75, the Holt 120 and to a lesser extent the Holt 60. The Holt 75 was first produced in 1913.[2] It used two tracks for steering. It had a maximum speed of {{convert|15|mph}} and had a gasoline engine.[2] In addition to US production 442 Holt 75s were built in Britain by Ruston & Hornsby in Lincoln.[2] Production of the Holt 75 was to continue post war until 1924.[2] The {{convert|120|hp}} model had a tiller-type steering wheel at the front that was usually covered. It weighed about {{convert|18000|lbs|kg|sp=us}}.[3] It was developed in direct response to a request for a heavy artillery tractor.[2] The prototype was produced in 1914 with production beginning in 1915.[2] The Holt 60 which saw limited use in the war was introduced in 1911.[4] Literature
