810B-8X8 by Timberjack: four-cylinder engine rated at 81 kW, built in 1999 as an eight-wheel-drive forestry machine for timber extraction.
Timberjack was a forestry-equipment manufacturer whose brand became part of John Deere Forestry in 2000. The 810B-8X8, an eight-wheel-drive forwarder, still belongs to the independent Timberjack era and falls into the forestry tractor category, which SpecCodex records within tractors.

The 810B-8X8 is powered by a four-cylinder engine of 3,990 cm³ displacement, delivering 81 kW. At a length of 8,450 mm, a width of 2,660 mm, an unladen weight of 10,500 kg and a permissible gross weight of 21,000 kg, this is a large, eight-wheeled forestry machine for timber extraction, with a payload capacity in the order of ten tonnes.
Eight-wheel-drive forwarders like the 810B-8X8 carry felled and delimbed timber on a load bed between the front and rear modules to the extraction route, rather than dragging it along the ground as a skidder does. The large gap between gross and unladen weight reflects the substantial log payload typical of this machine class. Oscillating axles on both the front and rear modules keep the wheels in contact with uneven forest ground.
On a used forestry machine of this size and age, the condition of the articulation joint between the front and rear modules and of the hydraulic loading crane matters most, since both assemblies bear heavy strain during forestry work on uneven terrain. The frame and axles should also be checked for cracks and wear.
