Manufacturing of the new H 520 model is not completely trouble-free, as problems are encountered with the grapple operation. Ponsse faces great challenges after about 30 grapples are sold to the customers. Due to these problems, flexibility is required from the employees and work is carried out non-stop so as to repair the harvester head malfunctions. Learning from the experience, Ponsse develops a new harvester head, H 60, at the end of the same year.

The company launches grapple processors and later on grapple harvesters. Several types of grapple harvesters are put to the test at Einari Vidgrén's logging sites, and since a satisfactory model is not found, Einari states: "We'll make it ourselves."
