The '''Ford Model TT''' is a truck made by [[Ford Motor Company|Ford]].  It was based on the [[Ford Model T]], but with a longer wheelbase, and a heavier frame and rear [[axle]], giving it a rating of {{convert|1|ST|lk=on}}.

==Production==
When the first three units were produced in 1917, the Model TT was sold as a [[chassis]] with the buyer supplying a body. The price was $600.  Starting in 1924, the truck was available with a factory-produced body. By 1926 the price had dropped to $325.{{sfn|Gunnell|2003|page=6}} In 1925, a hand-operated windshield wiper was added.{{sfn|Gunnell|2003|page=37}}

===Military production===
In his ''World Encyclopedia of Military Vehicles'', author Pat Ware writes that: "During World War I, the Model&nbsp;T was ... standardized in the "light" class. The first truck, using a long-wheelbase chassis designated Model&nbsp;TT, was launched in 1917. Although Ford ... was a pacifist, he was ... happy to supply the US Army with more than 12,000 of these vehicles,..."<ref name=WareEncy>{{cite book |last=Ware |first=Pat |title=The World Encyclopedia of Military Vehicles |year=2010 |publisher=Lorenz Books |isbn=978-0-7548-2052-9 |page=234}}</ref> and: ''"There was no civilian production of the Model Ts between 1917 and 1918."''

Further on, Ware writes: "The Model T was widely used by the US and British armies during World War I as a staff car, ambulance, van and cargo truck, even as an artillery tractor, for which application the truck was fitted with twinned rear tyres."<ref name=WareEncy/> Many remained in service into the 1930s.

Below are the numbers of Model T trucks produced each year, not including Canadian production.<ref>{{cite web |url=http://www.mtfca.com/encyclo/fdprod.htm |title=Ford Production |publisher=Model T Ford Club of America |access-date=2015-03-25}}</ref>

==Drivetrain==

The rear axle of the TT has a [[worm drive]]{{sfn|Gunnell|2003|page=6}} and [[Crown gear|crown wheel]], unlike the Model T's crown wheel and [[pinion]]. The worm is located at the end of the drive shaft and above the crown wheel. The wheelbase of the Model TT is {{Convert|125|in|mm|0}}, compared to {{convert|100|in|mm|0}} for the Model T. It was often equipped with an accessory [[gearbox]], such as the [[Ruckstell]] or Jumbo gearboxes, which allow the truck to have intermediate gears between low and high, useful for hill climbing.

The Model TT was very durable for the time, but slow when compared to other trucks.<ref>{{cite web
