I have a Statesman 42" rider, an oldie but goodie. I use it to mow in season and pull a Cyclone Leaf Vac (great product, hands down) in the fall, so the blades get worked. I sharpen them(mulcher, so 2 lg and 2 small) 3-4- times a year, and it's no biggie, until the last time. I try to replace the blades as I found them each time.

I removed, sharpened and re-installed the blades as I always do. I balance them a bit crudely, but it's never been a problem. This last time, after a big leaf season, I took my compressor and blew leaf bits out of pullys, above the deck, etc.

The deck, once I engage the blades, really goes wild with a shimmy and such. I removed, checked balance and replaced the blades, and got the same problem.
Do I just need to replace the blades, since they've been sharpened so much?

What can you suggest, experts? I am a contractor, so if it's not bricks or wood, get myself in trouble real fast!

Well, are you getting the blade onto the spindle correctly? If you do not get it on correctly with the * shape, you will have vibration. Also, a worn belt can cause this problem. And the spindle bearings can be in bad shape and cause this also. Then there is always the possibility of you having a broken spindle assembly at the mounting points, or bolts missing that hold the spindle assembly to the deck. And even though a blade appears to be "balanced" it can still be bent and cause vibration.

Great advice, my friend. Installed a new belt today, and the rock n roll is no more!

Thanks,
