Landing: | is the location where the yarder is positioned to receive the logs |
Outriggers | are the hydraulic feet or pads put out by the yarder to level the operating base and securely set the yarder in place |
Tower | is the crane like raised tower which the cables operate from to provide height for extraction of logs. |
