I personally think this should be a feature with a specific tool you can buy/find (like a chainsaw, as you say), and it would give more purpose to the woodchipper to be able to clean up the debris after, but the more you chop, the more one of the anomalous radar pings goes from ambient and interesting to scary and malicious (I'm sure those who know which one I'm talking about would agree it would fit- maybe even start to overpopulate the map or grown in size/shape)
