I am considering to buy a HM122, if I can get it shipped to the Yukon @ a reasonable rate. A key question is - which engine shall I go with? My logs mainly will be spruce around 15" and poplar maybe 20" max. Is it worthwhile to go with the bigger engine or will I just waste gasoline? I will run the mill a few days a year only - if I need boards to fix up or enhance my cabin.
