The Woodland Mills auto lube system easily attaches to the HM122, HM126 and HM130 sawmills. This unique system will automatically turn the blade lubricant on when the throttle is depressed and turn it off when the throttle is released. With this innovative feature, you will never need to remember to manually turn the blade lubricant on or off again and saves the operator multiple steps on each cut made. Less steps equals more cutting! Patent Pending
