It is a beast! Im not a fan of the steering contrals. You pull down one lever to engage the drive, and other handles control the right/left clutch/brake. It would be a better design to have the right/left levers to be engage when squeezed. Not disengaged when squeezed.

The flail mower does the job. I'm glad I got it. When the mower was delivered one of the tires was flat. I have trouble keeping air in it. Other than the flat tire I've very pleased.
