You can hear it’s electric⚡️ ~ 15 years ago they used to be hydraulic but nowadays it’s almost 💯% electric (electromechanical), at least in the developed countries… They are run from 3-phase electrical power into a high voltage inverter that runs a high voltage motor. The motor and often also the inverter are cooled with normal tap water. Most of these are developed and manufactured in Europe. I think Pentruder was the first ones. ruclips.net/video/lx6qDbZbcxk/видео.html Then there’s Husqvarna Construction Products that has brought their industrial design and mass manufacturing capabilities. ruclips.net/video/jLG2iPVb-kQ/видео.html Except for big blades, there are also wire and saw sword blades. All of the cutting material is diamond-coated.
