vibration

I have a Craftsman ZTS 7500 with a 26hp Kohler engine. I was cutting grass yesterday and it just started vibrating. Can anyone tell me what would cause this? Thanks

What is vibrating?
Does it do it when the pto is on or off.

If only when the pto is on then check the blades. Could be loose or have something on them. Take the belt off and spin the blades see if they wobble or make noise.

I am not sure what is vibration, but you can feel it when blades are engage or not.

Broken crank or bearing cap (perish thought), flywheel loose. Engine mounting to metal chassis. Let's hope it's loose blade (s).

Ok so we know it is not the deck or the blades. Let's start easy and check the engine to frame bolts. You will have to get under the mower to get to them. There will be 4 of them. If just one of them is loose or will vibrate. While you are under there check the pulley on the engine see if it is loose.
