Jan van Dam (1947) settles as agricultural mechanisation company in a smithy on the Hamsestraat in Opheusden. From the tree nurseries in the direct neighbourhood came the question for specific solutions for this sector. The first own machine was the dirigible CDO-60 tree undercutting plough with the LR-3 cable winch in 1970. Over the course of more than 50 years the company developed into a manufacturer of tree nursery machines. Beside it machines have been imported and sold in the Netherlands and surrounding countries.
