Wood-mizer LT70

Cutting 16 foot 4x4s out of cottonwood. This mill is 11 years old(2003) with over 8000 hours on the meter. It cuts like the day I got it and gives me very little grief as far as repairs go. I made several modifications over the years(air debarker in/out control, hydraulics work in any position as opposed to just either end, and replaced the pulley on the 190 amp alternator with a smaller one to get more hormones when the mill is at idle(hence the squeeking in the video). This mill has supported me and my family for 11 years( main source of income). After running it all these years. the only fault I can find with the unit is I wish that the up/down and hydraulics were faster. The 8 cuts I made in this log took around 1 and 2/3rds minutes yet the log was on the mill for at least 5 minutes.
