Logbear - Model F4000 -Forwarder

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.
