This wheeled tractor is a Latil KTL 4 which was made beginning in 1934. The French army had procured 163 exemplars. (Photo: German federal archive via Wikimedia Commons; License: Creative Commons BY-SA-3.0-gb)
This Latil KTL 4 of a later production series was photographed during engine maintenance. Observe the Latil inscription on the newly designed radiator and the new shaped mudguards..
Some Latil KTL 4 had two way equipment for the drive on railroad tracks. The permanent lack of locomotives could be partly compensated with the service of such vehicles.
