Raptor Harmonic Vibration

[83ragtop50]

I just purchased a 52" Raptor to cut my 3+ares. I am impressed by the mower, but am concerned about what seems to be a harmonics induce vibration. When I engage the blades there is what ems o be a harmonic that sets up in possible the mower frame. It cycles every 2-3 seconds. Is this typical? I am concerned about nothing?

Balance your blades _very_ carefully. I picked up a 5/8" OD ball bearing and mounted it to the side of my workbench. After balancing to the detection capability of the bearing all my deck wobble and cyclic noises went away.
