EarthScope: Mowing Hay

Image

Station M49A is located in the corner of a pasture field. Just before 2:00PM EDT(18:00 UTC) a friend mowed the hay in that field. What does a large tractor and mowing machine look like on a seismograph as it goes around and around the field, slowly getting farther and farther away? (I think you can see it.)
