In the series about sturdy harvesters, we have now come to the John Deere 1470G – the top of the line harvester in the John Deere range. This time, we managed to find a machine that had been in use less than a week.
John Deere Forestry
John Deere Forestry has a long and interesting history. For us older dudes, here in northern Europe, we still refer to John Deere as ÖSA, or even Kockums. Because the fact is that John Deere Forestry is a conglomerate of many brands.
What happened during the 70’s and 80’s was that the Finnish company Rauma Repola purchased Kockums, Lokomo, ÖSA, Mini Brunett, some more and eventually Timberjack. They all teamed up, first under the brand FMG (Forest Machine Group) and then Timberjack. In 2005 John Deere bought it all, lightened up the green color a bit and threw the Timberjack brand and the dark green color in the garbage bin. That was bald!!
John Deere 1470G harvester
John Deere Forestry is one of the largest manufacturers of large-scale logging equipment. They are by far the largest manufacturer of machines for CTL (Cut-To-Length) Worldwide.
They have five wheeled CTL-harvesters in their range; 1070G, 1170G, 1270G, 1270G 8wd and the 1470G. You can read more about all their forestry ranges here.
As mentioned above, the 1470G is the biggest of the JD harvesters. It´s competing with Komatsu 951, Rottne H21, Ponsse Bear and EcoLog 590 in the same segment.
The owner of this 1470G is the company Stigssons Skogsservice AB (Stigssons Forestry Service inc.). A family-owned company with a long history that spans over generations. Today they have the 1470G, one JD 1510G forwarder and one JD 1910G forwarder that is mainly used for scarifying.
