Both the yellow and blue flags are 16" long. The blue flag has been inserted into the hole created from this machine to a depth of 9". The yellow flag has only been inserted enough to stand on its own to show you how deep the holes are. This machine injects compressed air into the ground and fractures the soil profile with very minimal surface disruption! This will help our greens drain and promote stronger and healthier turf.
Please visit our facebook page to see the video of this machine. I apologize for my fingertip in the picture!
