What do i need to do to fix my lawn mower by myself?

Question

A few weeks ago i hit a stump in my back yard, the lawn mower cut off immediately,now it is really hard to start it. When it runs it is really weak,when i go through thicker grass it starts to rattle and slow down and sometimes cuts off. If it cuts off from the thick grass the lawn mower locks up so i can't start it. The pull string won't move. So I let it rest then i go and turn the blade and then i am able to start it, but it takes for ever to start.What do i need to do to fix it

Answer 1

most likely your crankshaft is bent.. it is cheaper to buy a new one....

Answer 2

you have bent the shaft or sheared the square key between the flywheel and crankshaft.

Answer 3

You bent the shaft or the blade. If it's the blade you can buy a replacement blade for it. But it actually sounds like the shaft is bent, it'll be cheaper to buy another mower. You have to watch where you are going, I know you have power in your hands and you think you can go over anything, but you can't.
