Holmac has been a trusted brand since 1969. Their main focus was putting precision into all of their products. They started with putting hydraulics into nursery tools such as the hydraulic shovel. It wasn’t until 1990 that Holmac became a leading international company because they had a wide range of tracked tree diggers. These tree diggers vary based on the size of their rootball cutter. Some rootball cutters range fro 25-80 cm, 25-100, and 50-150 cm. Almost all of their tree diggers have a sideways cutting movement making it easy to get to the narrowest rows of plants. They have many models of tree diggers ranging from the HZC series to the HM series. If you are looking for a tree digger you can trust, trust Holmac to get the job done.
