Log Lathe LL-41
Productivity According to manufacturer's web site:

These numbers can be converted to 13-25 logs (20ft/6m) per 8 hours ~~  1 log takes 19 to 36 minutes to be processed
Productivity depends on logs quality, experience of operator and how fast logs are load/unload to the lathe. In average skilled operator will spend 20-40 minutes per 20 ft (6m) log including loading, turning down to necessary diameter, grooving, notching, kerfing and unloading. 20-40 minutes per log can be interpreted as 12-24 logс per 8 hours.

LL-41 is able to remove up to 6 cm (2.5")inches of wood layer on log radius what is 12 cm (5" per log diameter)

 Work of horizontal mill cutter.
