Finish Nailer Repair - Replacing the Driver Guide (Ridgid Part # 79004001022)
Mower blades can be sharpened several times to extend their life and ensure that your grass gets a healthy cut, but they can only be filed so many times before a blade replacement is necessary.
Homeowners can save themselves quite a bit of money performing simple repairs like this one. New mower blades tend to be reasonably priced, and mower blade replacements usually only require the use of a wrench.
For information about matching a replacement mower blade to your mower, please read our article, Lawn Mower Blade Measurements and Types.
Steps to Replace a Lawn Mower Blade
Mower blade mounting designs vary, but the basic steps are usually the same. Most mowers have use a very simple blade mounting design like the mower we use below as an example .
1. Set the mower on its side.
Always set the mower on the side that does not have a carburetor so that the mower's fuel does not leak out.
Make sure the gas and oil caps are screwed on tightly before tipping the mower. 2. Remove the fasteners holding the mower blade on.
This just means removing one nut on our example mower, and this is usually the case for most mower models.
Use one hand to steady the blade when first loosening the nut.
3. Remove the old mower blade.
Make sure to hang on to any mower pieces that help mount the blade, like the retaining plate pictured below.
4. Install the new blade.
Most mower designs will not allow the mower blade to be installed with the wrong side down.
Our example mower blade and its retaining plate are shaped so that the blade can only be installed in the correct position.
It is possible to incorrectly install mower blades on some mowers. And it's always possible to install a blade too loosely.
Vibration and poor lawn cutting will quickly make a poor mower blade installation noticeable. A quick adjustment is all it takes to get back to work in the event of an incorrect installation.
