As if some of us didn't already feel old enough, Yanmar has just announced the 50th anniversary of the YFW500D - the world’s first tracked carrier equipped with a Yanmar diesel engine.

Created in 1971, the YFW500D was officially the world’s first tracked carrier. The initial model used the undercarriage of a Yanmar rubber crawler combine harvester, adding a cargo box to enable it to transport materials on soft ground. The pioneering model was then the  first in a long line of products from Yanmar, each of which developed to meet specific market needs.

Yanmar is marking the milestone by renewing its commitment to developing high-performance products and solutions that offer reliability and value for customers.

Pictured here, the 1971 original above and a more recent iteration below - both splendid looking machines.
