Suddenly have poor cutting problem

OK, so the last two weeks I've had a terrible time with my mower leaving uneven cuts. Not sure what's wrong. Having to double cut a lot. Never had this problem. Have sharpened blades, cut in short overlapping strips, used a mulcher kit with mulcher blades....nothing seems to alleviate the problem. Even had 2 customer complaints recently. I've read where a lot of you double cut regularly, so perhaps I will need to start doing that. Only thing I can figure out is that I hit something last year and it bent the deck a bit. Maybe it threw off one of the spindles or something. I'ts a 3 year olf Big Dog 42" mower. Any ideas?

Well you can tell if the deck or spindles are out of wack. Put on three straight blades and see how they line up side by side. Are all of your deck belts tight, no slippage?

Does your mower sound or feel different than it did in the past?

sounds like something's bent. Blade, Spindle or Deck. Jack up your mower and align your blades so the ends of the blades are "end to end". Is one higher than the other? If so, replace the blade that's higher, and if that fixes the problem, you had a bent blade. If it doesn't fix it, you have either a bent spindle or deck. If you have a big commercial, thick, welded, steel deck and you haven't hit something big enough to throw you over the handle bars, it may be your spindle. Good luck.

All good suggestions. To best check your spindles, first remove blade belt...then align blades in a row. Wiggle blades to check for up/down play.

Have you raised your deck up some from last year, or earlier this season, and if so, what height are you cutting at? Some decks don't do well above 3"-3.25". Also, mulch kits don't usually leave the smoothest or nicest finish.

Is the deck clean? A dirty deck really messes up the airflow.

recently this problem too. I had one bent spindle. Further, the deck pitch was way out of whack.

For the spindles, turn the blades and see if the tips line up. If the blades don't line up the blades or spindle could be bent. Best to put on brand new fresh blades.

Follow the directions in the owners manual for leveling the deck.

I about guarantee this this will fix your problem.

Check tire pressure too.
