Worked as expected.
Arrived quickly. Fit very well on mower. For the price I wish the bolt's for it came with it but they did not. So keep that in mind when you order.

I had removed the deck and made several repairs to holes in the deck then I replaced the spindle and spindle mount. Then remounted the deck, connected the belts to drive pulleys and I was back mowing my four acres with a machine that runs better than new. Thank you
