Question Push mower dies when blades touch grass.

Hey all,

I have a troy-bilt self-propelled push mower. It was working fine until I hit a decent size rock (~5 inches). After that, it will start up fine, but once the blades touch the grass...it acts like I am trying to mow 8 inch grass blades that are soaked with water.

The mower keeps wanting to die.

So my question I hope is obvious..."Does anyone have an answer to help me fix my mower?"

Thank you!

Blade is most likely bent and one side is lower digging into grass.

Remove spark plug and tie safety handle allowing you to spin blade freely. Take a visual mark inside deck housing and spin blade. I will bet one side is much lower. Even though mower is starting fine I would check flywheel key, may be partially sheared. Lastly while spinning blade look at crankshaft to see if it is bent.

Good luck
