Re for OAS-forests:
I use Rottne 2004, before FMG 0470 from 1991(!), but in CZ are about 10 Vimek 404. The 404 are using in first thinnings, in 20+ years old forests. The average tree is started at 0,3 m3. I know one company from South Bohemia, they has two 404 (now maybe 3). One is the first 404 in czech and its model T. Maximum average tree is 0,14 m3 and the second machine is version T3 and there is max. 0,19.
Small scale machines, like Vimek, Malwa, Novotny or Entracon are very popular here, because low impact, but if you are in hard terrain and long distance you have half money. This machines are reuquired by small forest owners, but also big owners and companies.Extra put emphasis is on thin branch road, typically 2 metres. Its frequently condition in contracts for thinnings in 40 years old forests. In total, machines used in Sweden for thinning 9 tons load, are often for foresters so big and they wanted machines like Vimek etc..
Re for Rickard_e:
Condition in Czech depend where you are. In mountains are steep slopes, where you can logging yust by horses, skidders and cableways. On highlands you can cutting by harvesters or forwarders. Im working in highlands, there are many places, where are steep slopes and wetlands, but not in swedish scale. Also stones are here, but in small areas. In total, Sweden looks much harder, especially for forwarding.
What is harder in Czech in my opinion is the sorting of timber. We are working in thinning from 20 to 80 years old forests. So we cutting 2, 2,5, 3, 4, 5, sometimes 6 m long pieces of timber. 2 m is the pulpwood, rest is roundwood, sorting by diameter. Also pulpwood can be sorted by diameter. So sometimes you can have two sorts from 2m, two from 3m, three from 4m etc..
