Holmac is the international market-leader due to their broad selection of rootballing machines on caterpillar tyres, distinguished by the size of the lumps that they can unearth respetively, varying in diameter from 25 to 180 cm. Some machines are equipped with a lateral uprooting system with which plants can be uprooted in very narrow channels. Almost all models have caterpillar tyres with a patented broadening and lifting system, making the moving of large plants possible. Furthermore, the transporter on caterpillar tyres, the gutter digger and the pot bearer are widely used in the tree and plant cultivation industry.
