Timberjack is a manufacturer of forestry machinery for both cut-to-length and whole tree logging, and was a subsidiary of John Deere from 2000 to 2006.
Timberjack was founded in Woodstock, Ontario, in the 1950s by Wes Magill and Robert Simmons, who designed an articulated four-wheel drive tractor with a winch at the back.
John Deere purchased Timberjack and continued the green, black and yellow paint scheme.
Other well known forest machine brands, which have been incorporated into FMG-Timberjack were Swedish Kockums, ÖSA and Bruun System as well as Finnish LOKOMO.
In December 2000 John Deere bought Timberjack from Metso Corporation (formerly Rauma-Repola) for $570 million which also included the purchase of a separate company, Waratah, a leading manufacturer of heavy-duty harvester heads.
