Latil H14 TL10

The Latil H14 TL10 is an all-wheel drive agricultural and forestry tractor produced by Latil and later Saviem from 1947 to 1962 through various evolutions. It was replaced by the Saviem TL21/22/23 range.

History
In 1947, Latil unveiled its H14 TL10 agricultural and forestry tractor, mounting the H14 engine, a slightly modified H1. By 1949, it was sold in the United Kingdom as a multiporpose tractor (adding tractor unit for road and off-road) with the name H11 TL10.

In the 1950s, TL10s equipped with a winch had some military use by engineering corps of the French Army.

In 1957, after Latil was integrated into the Saviem company, a minor evolution of the TL10, the H14 TL12R, was introduced. In December 1960, the company unveiled the H14 TL12, a cheaper variant of the TL12R without trailer brake (which meant it could only be used as a towing tractor and not as an agricultural one).

Technical details
The main engine used for the tractor is the H14, an evolution of the pre-World War II H1 with a direct injection system licensed from Gardner. It is a inline-four diesel engine with a 108 mm bore and a 152 mm stroke, giving a displacement of 5,585 cc (earlier version) and 5,569 cc (later version). Its power was between 65 PS at 1,500 rpm (earlier version) and 85 PS at 1,850 rpm (later version). As an optional, earlier TL10 versions could be equipped with a similar petrol engine codenamed as M14.

The British version had a different engine codenamed as H11 by Latil and supplied by Meadows, the 4 DC-420. It is an inline four diesel with a bore and stroke of 130 mm, giving a displacement of 6,902 cc. Maximum engine power was 70 bhp at 1,900 rpm and its torque 233 lbft at 1,000 rpm.

The gearbox is a 4-speed unit with a transfer case giving 8 forward speeds and 2 reverses. The gearbox output shaft is connected to the front and rear axles, making the tractor on permanent four-wheel drive. Levers in the cabin are connected to the differential system to lock the drive on any axle.

The tractor has a four-wheel steering system, with the steering drop arm connected to the stub assemblies of both axles, giving it a turning radius of 15 ft. The H14 TL10 and the H14 TL12R were available in a "navette" version, with a panoramic cabin, double driving positions with two vertical steering wheels and reversed gears.

The tractor's wheelbase is 2.4 m and it weighs over 3 tonnes. It has air brakes. Suspension is by straight leaf springs.

Later developments
As the company marketed the H14 TL12, it also introduced the TL20, a simpler version with mechanical instead of air brakes, a 3-speed instead of four-speed gearbox, and a redesigned grille.

In October 1961, Saviem unveiled a new range of tractors with various design changes: the TL21, TL22, and TL23. The TL21 was an agricultural and forestry tractor, the TL22 a towing tractor and the TL23 a prime mover of 24 tones gross combined weight. The first has mechanical braking and the others air braking. All of them are powered by the F 120.51 engine,  an inline-four diesel engine with a 110 mm bore and a 120 mm stroke, giving a displacement of 4,561 cc. The maximum power of it was 100 PS at 2,500 rpm.

In 1962, the licence for the tractors' production was sold to the Creusot-Loire conglomerate, which marketed them as the Latil Batignolles.
