This is the sawmill I spent 10 years of my career with. You'd be surprised how much power this "carriage has". 3/8" sawkerf!!! Yes, hard to believe. 3/8" waste every cut we made in that old growth douglas fir. They don't run to much anymore, extremely hard to get the bigger fir logs for clears. I "offbeared" from this 440 volt beast!!!!! Look carefully, there is a horizontal saw there also. Each one on seperate motor, maximum size of cut 12X 16. Maximum log length 40 feet.
