Riding Mower technique question. Am I just doing it wrong?

[turbofiat124]

This was what my yard looked like back in the summer with bent blades. I had hit something a few weeks prior. Then hit something again and started hearing this awful racket.

I remember running over a shepherds hook my daughter threw in the yard before I could stop and think that was what wrecked my blades.

What irritates me the last time I mowed, my yard is starting to look like this again! I don't think I've hit anything but I think I need to level my deck or adjust wheels on my deck.

Check your spindles and make sure tight and not broken.

I did inspect them before putting the blades on and they seemed fine but they could have had a hairline crack and eventually broke.
