When we first introduced the patented GP, it was the only forestry tool to combine the versatility of a grapple with the functionality of a processor. Everything from handling, sorting and loading to delimbing, measuring and cutting could be handled by just one machine.
Building on the GP’s solid foundation, ProSeries introduces innovative new features that improve reliability and efficiency in several critical ways. From more precise measuring with its new measuring wheel design, to the advanced control technology of the new Forester Control System, the GP ProSeries arrives with several significant upgrades.
