This shows the hydraulic feed with "Smart Feed" feed rate controller pausing the feed to ensure optimum flywheel/engine rpm. This is the same machine that in our other video, shows the unit rotating 360 degrees to allow for the operator to feed from any location for maximum efficiency, safety and production speed. ask how you can get an entire fleet of ECHO Chainsaws, pole pruners and blowers for your tree service crew for FREE!
