History

1937 British-assembled KTL for roads with modifications, marketed as Traulier. Latil 4X4 (in front of a row of portaloos in Bedfordshire) mfd 1937 first reg in UK sep 1987 3686cc.JPG
1937 British-assembled KTL for roads with modifications, marketed as Traulier.

The Latil KTL tractor was introduced in 1929. [1] In October of that year, it was presented in the United Kingdom [2] and, by early 1931, it was being imported into the country. [3] By 1932, it started to be assembled locally [4] under licence by the British company Shelvoke and Drewry [5] with some minor modifications. [4]

From 1932 onwards, the KTL was tested by the French military as a replacement for the earlier Latil TL tractor for towing the 105 L 13 canon, as the previous tractor was considered too slow. In 1934, The  military finally commissioned the K TL4, a KTL with extended wheelbase, which was still slow for that usage. About 163 were built. [6]

In 1934, another KTL-based vehicle with extended wheelbase, the G TL3 prototype, was tested as a hauler for the 75 CA anti-aircraft gun, but it had a high centre of gravity and a narrow track relative to its wheelbase, which made it lack stability and off-roading capabilities. In 1937, the design was definetively abandoned. The French military adopted another Latil model, the Latil M2 TZ, and various trucks, among them the Berliet GDLS 30. [7]

Technical details

The main engine used for the tractor is the K, [6] an inline-four petrol engine with a 90 mm bore and a 130 mm stroke, [8] [9] giving a displacement of 3,308 cc. [6] [10] Its maximum power is 40  bhp (41  PS ; 30  kW ) at 1,900 rpm. [10] Its fiscal power is rated at 13 CV. [8] [9] As an optional, the KTL could be equipped with not specified  diesel and gasifier-running engines. [11]

The gearbox is a 3-speed manual unit with a transfer case [12] giving 6 forward speeds and 2 reverses. [6] [10] [12] The differential system can lock the drive on any axle through a lever next to the driver's seat. [13] The tractor has a four-wheel steering system. The wheels could be mounted with retractable spuds for improving grip on some surfaces. [12]

For commercial use, the KTL was offered in two versions: agriculture/forestry tractor [8] and road tractor, [9] which mainly differ on bodywork and hauling equipment. [8] [9] They can haul between 5 and 10 tonnes, depending on version. Both have the same dimensions: a (main) length of 3.73 m (12.2 ft) a height (without roof) of 1.941 m (6.37 ft), a width of 1.79 m (5.9 ft), a track of 1.493 m (4.90 ft). [8] [9] The wheels have the same size both on front and rear: [1]   36  in (91  cm ) x 6 in (15 cm). [8] [9] [10]

The tractor's wheelbase is 2.3 m (7.5 ft). [8] [9] Its weight (without equipment) is over 2 tonnes. [10] It has drum brakes. Suspension is by long straight leaf springs. [10] [14]

K TL4 and G TL3

The K TL4 is a version of the KTL with a wheelbase extended to 2.7 m (8.9 ft). For military use, it was offered in two versions: a tractor for cannon on pivot and an ammunition-carrying tractor with extended bodywork. Both have a length of 4.7 m (15 ft), a height of 2.5 m (8.2 ft) (with roof) and a track of 1.5 m (4.9 ft). They differ in width: the cannon on pivot version is 2.1 m (6.9 ft) and the ammunition-carrying is 2.22 m (7.3 ft). The K engine in military configuration delivered 36 PS (36 bhp; 26 kW). The payload is 950 kg (2,090 lb). The tractor's top speed is 35 km/h. [6]

The G TL3 had a wheelbase of 4.3 m (14 ft). [15]

Latil JTL

The Latil JTL is a similar contemporary tractor with the J engine,  an inline-four petrol unit with a with a 85 mm bore and a 130 mm stroke. Its fiscal power is rated at 11 CV. [16]

The tractor can haul the same as the KTL (5 to 10 tonnes). It was offered with the same variants. [16]
