What is wrong if my riding lawn mower leaves uneven grass?

Answer by  thattractorguy (2970)

Have a look at the mower deck. You may have hit something with it and bent it or bent a support bracket that attaches it to the mower. If you notice something bent, remove the part and straighten it out. This could also be caused by broken blades. If you see a broken blade, replace it.

Check the mowing deck for level. The springs and arms should lift and lower the deck evenly. Check tire inflation, missing or chunked deck wheels, and cutting blade bearing and belt condition. Don't cut too much per pass, and mow up and down terrain, not across it.

The first thing is to check your blades. Unbalanced or worn blades will not cut evenely. The next major thing is to check your wheel heights. Make sure they are even on the mower and mower case. Then check the underside of the mower for build up. We grass is famous for this.

You might have to adjust the blade on it. That might be what is causing the problem. Or you should take it in to have it fixed. Or go get a manual to help you fix it. Or take it in to the repair shop to have it fixed. best of luck.

You may have bent the spindle mounting surface on the mower deck. Check for a bent spindle shaft. If OK, check if one end of the blade is low and the the other end high. If so then you probably have a bent deck.
