0

Logbear F4000 Forwarder is developed to meet the demands from todays first thinnings. It is very agile, and with the carrying type tracks driving can also be made succesfully from swampy areas. The tracks also ensure driving in deep snow at wintertime. Size of the machine is related to the wood amount from a first thinning, which in Scandinavia is on level of 40 m³ /ha. Loading space is 1.9 m² meaning a. 5.5-5.8 real cubic meters/load with a. 4.5 m long wood. Tracks are carrying type made from special components from Finland. The developement work has created a relatively light track with exceptional long life time to a low price. For areas with extremely deep snow 70 cm or more and especially in hilly terrain there are tracks with snowbars.
