By adding a cargo box to the undercarriage of a combine harvester, Yanmar created the YFW500D, the world's first Tracked carrier. The YFW500D was powered by a Yanmar diesel engine and could transport materials on soft ground where trucks and dump trucks could not enter.
The YFW26D had a large loading capacity of 3 tons and was equipped with a 17-horsepower Yanmar vertical water-cooled three-cylinder diesel engine that enabled it to run quickly on slopes. The tough steel crawler made it a favorite of worksites.
A rubber crawler that achieved a speed of 11 km/h, about twice the speed of conventional crawlers. The high-speed YFW25R carrier also featured the industry's first reverse seat and was the prototype for the C30R model.
Equipped with a 64-horsepower Yanmar vertical water-cooled fourcylinder diesel engine, the YFW40R was launched in pursuit of not only running speed and power, but also comfort and used a large rubber crawler to reduce operator fatigue in a highly maneuverable HST. This model was the prototype for the C50R.
A compact carrier with a width of only 950mm built tough to work hard on construction sites. Until the YFW8R, tracked carriers had their driver’s seats mounted to one side or the other. But with the YFW8R, for the first time in the industry, the seat was placed in the center making it easy to get on and off from both sides and provided better visibility. This model was the prototype for the C12R.
The C6R was a 790mm wide mini carrier specially designed for civil engineering and suitable for urban renewal in densely populated residential neighborhoods and narrow alleys. With the power and sturdy design of a construction machine, it was used for a wide range of tasks from civil engineering work to landscaping and forest road work in narrow areas where small pick-up trucks could not go.
