About half to 3/4. . The entire side yard on one side, the entire back yard and a portion of other side and portion of front . One was a massive white pine and other was a 125 year old Oak both close to house. In order to get to them they had to drive all over the lawn with Kaboda and chippers . Their truck got stuck in mud at one point. It was excruciating for someone like me to watch unfold to their lawn . And then it never snowed so I had to look at it from Feb - early May .
