Kubota zd28 blades knock. When I installed them, and spun them they were fine. When I engage the pot, the left side hits the middle.

Typical deck blades are not timed. But there are some , with cogged drive belt, that have t be timed 90 degrees from eachother.
Customer: replied 1 year ago.
I've tried half a dozen times with different alignments. It starts fine then knocks a few times. I'm wondering if it could be the bell under the deck or something.
Expert:  Curtis B. replied 1 year ago.
You changed the blades and now they hit? Exact same length as the old ones
Expert:  Curtis B. replied 1 year ago.
Your deck is not a timed deck!

I got the blades at the kubota dealership. Part number k5647-34340
Expert:  Curtis B. replied 1 year ago.
Shows to be correct number. Did you compare them to old ones? Could either of the spindles be bent?
Customer: replied 1 year ago.
Seem to be the same size. Not sure about the spindles. How would I check that? The pulley has no slack and belt is tight. It slips slightly if I really try to make it. But not easy.
Expert:  Curtis B. replied 1 year ago.
measure the blade tip to the inner deck, at 90 degree increments, all should be same, if not look for blade that is not on correctly or spindle is bent.
