The possible causes of a lawn mower blade spinning but not cutting grass include a damaged or wrongly installed blade, a dull blade, or damaged lawnmower tires. Other possible reasons can be improper tire pressure, a clogged deck, or a broken mower belt.
While there are several reasons this might happen, it is most commonly the result of an uneven deck or misaligned blades. Make sure the blades are facing the correct direction and are not warped. Check the mower spindle and repair it if necessary. Check if the deck is level and if not repair or replace it.
If the engine dies when the blades engage, it could be the result of a damaged safety switch. The first step in assessing the safety switch is to make sure it is plugged in securely. The switch is located underneath the seat, and you may have to remove the seat to reach it.
An unbalanced blade spinning that fast will cause a significant amount of vibration, which will put stress on yout blade shaft, spindle, and even the engine. So if you want to get the most life out of your mower… keep the blades balanced!
Why is my mower leaving a trail of grass on the right hand side? The issue is probably the amount of material that is being cut. The blades turn counter clockwise, so if you try to cut more material than the unit can handle, you will have a windrow of material build up on the right hand side.
Step One: Don`t Mow A Wet Lawn
When there is moisture the clippings will stick to the lawn mower blades and deck making clogs inevitable. This of course leads to large clumps of grass all over the lawn. These clumps may even get stuck in the lawn mower, leaving you no choice but to work out the clogs yourself.
A dull blade can make your lawn appear yellow, brown and raggedy. A dull lawnmower blade may even pull up portions of the grass because it actually pulls on the entire plant instead of slicing through the blades of grass cleanly.
The spark plugs are worn or damaged
If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.
The causes of uneven cuts from your lawn mower are worn or dull blades, incorrect tire pressure, bent blades, or a clogged deck with grass. Also, due to the deck not being leveled, having an uneven spindle, or the belt may be in bad shape or at low speed.
Most, if not all, new lawn mower blades are ready to use right out of the box. They might not seem sharp to the touch and might even feel a little blunt. That is how they were designed, built, and delivered straight from the factory.

There is a jig that you can buy that makes this job SO much eaiser. It is a universal jig that clamps onto the deck and keeps the blade from spinning so you can use a ratchet to remove the nut holding the blade on. One name brand is called a “Blade Hog”. You should be able to find one of these at one of the bog box hardware stores.

I would like to replace the mulching blades on my Sears Craftsman riding mower with regular cutting blades. I can find plenty of sources for new mulching blades, but not cutting blades. My mower is a model 917.259541 tractor and the blades currently on it are part #134149. I want to make sure I get the right size to replace them.
