Normally you will start to hear a loud grumbling sound from underneath the mower when the blades are engaged. With the mower shut off, release the tension from the belt for the blades. Raise the deck so you can grab the blades from the bottom. You should not be able to rock the blades from side to side or up and down. If you can then you probably have a bad spindle. You can do this for wach of the spindles to check them all.
