Five out of six blades evaluated fell short of the Exmark original mower blade specification in one or more of the following key areas:. Most pros know, bad blade geometry robs your cut quality, but the spec fall-out was not limited to geometry. Looking even closer, we found that even the quality of the metal had been cheapened.

Most lawn mower blades are reverse threaded which is also known as right-hand threaded. This means you will remove the nut and bolt that holds the blades on by spinning the blade off counterclockwise.
If the mower blade bolt seems to be stuck, you can place a block of wood on the head of the bolt and hit the block with a hammer. This will shock the bolt and sometimes loosen it enough to help you remove it.
You may have a blade set up that uses a bolt and washer to secure the blade to the Exmark spindle. If you have a more current higher series Exmark deck you will be using a splined busing through the center of the mower blade.
Install the splined bushing if used on your blade assembly into the center of the blade along with the blade bolt and washer into the spindle. Secure the blade bolt until it is finger tight.
It can be frustrating to find the cut of your Exmark mower not cutting like it did when it was new. It may be leaving an unlevel cut, a strip of uncut grass or just make your lawn appear bad overall. I can help! Remove grass and debris from the underside of the deck and in the discharge deflector.

When it comes to purchasing replacements and sharpening the blades, how should you begin?
You can usually tell when this is happening by a heavy buildup of grass on one side of the blade but not the other. Excessive vibration as you mow can also indicate your blades need to be balanced. Sharpening your mower blades should be done anywhere between 8 and 25 hours of mower use. Personal mowers need sharpening only once or twice a season, but professional mowing companies will need to work this in much more often weekly or bi-weekly.
Cleaning the blades after each use provides you with an opportunity to examine blade edges for nicks, dents, dings, and other signs of damage. We recommend OEM replacement blades for a number of reasons. Our team is available to help with troubleshooting, installation questions, and other issues related to mower maintenance.
Additionally, any damage to your mower caused by generic blades may no longer fall under warranty.
