“…There is also a need to decrease silvicultural costs so as to maintain the profitability of forestry amid conditions of decreasing real stumpage values (Uotila 2005), and thus to preserve forest-owners' motivation for forestry (Harstela 2006). Mechanisation is aimed at both reducing the need of labour and attaining cost savings in planting (Rummukainen et al 2002, Harstela 2006, Rantala et al2009). …”

Need to mechanise tree-planting work have recently increased for many reasons. The newest planting and soil scarification device performing work in Nordic forests is the Finnish M-Planter. This study aims to clarify M-Planter's productivity in practice and show how various factors affect it. The follow-up data set covers 607 work shifts, of 13 operators with, in total, five M-Planters. The average productivity figures for the operators were 143 and 169 seedlings per effective working hour during the first and second planting season, respectively. Overall, the measured average productivity was 34.2% lower than that observed in an earlier work study of the M-Planter based on an experimental study design. On average, the operators learned to use the combination of the M-Planter and a base machine more efficiently while their experience in using it increased during the follow-up. Increasing number of stones and stumps as well as a thicker humus layer decreased productivity of the M-Planter. The study concludes that utilisation of the full productivity potential of the M-Planter requires not only good operators but also development of the whole planting service supply chain.

“…Koneellisessa kylvössä yhteen kylvölaikkuun tai muokkausjälkimetrille kylvettävä siemenmäärä annostellaan automaattisesti. Samalla voidaan seurata siemenkulutusta sekä kylvölaitteen toimintaa (Korhonen ja Mänty 1991, Rummukainen 2001. Koneellisessa kaivinkonekylvössä siemenannos suunnataan paljastettuun kivennäismaalaikkuun.…”
