All the Performance – low emissions. The original Först ST6 just got better. Wide hopper at the mouth, 6” x 8” capacity infeed, robust all-steel construction and delivering a phenomenal performance yet only producing 24hp from the Kubota 1505 engine. The blades catch onto the materials and pull them through the drum which produces a nice square chip that will quickly rot down. The swivel head allows you to direct the waste where you need it. The large intake allows kinked branches and, in some cases, whole plants to be fed in with little or no preparation.
