How to Change and Sharpen Your Kubota Lawn Mower Blades

Replace your Kubota lawn mower blade every year. A blade that wears quickly because it is exposed to excessive dirt, rocks, and gravel will need to be replaced more often.

THE BLADES MUST BE REPLACED

Regardless of whether you are using your Scag for residential or commercial use, it’s imperative to check the blades every few weeks. This is to make sure they don’t need to be replaced. If you use your mower professionally, you must replace the blades every few months. Changing the blades once a year is enough when you are mowing at home. Replacement of blades is crucial because damaged blades can cause problems with the entire mower, burn out the engine, and pose a safety risk.

Here’s how to replace your mower blades:

• The first step. The mower deck should be raised to the highest position.
• The second. Hold the cutter deck in place by inserting the lanyard pin in the uppermost cutting height position.
• The third. Make sure the blades do not rotate. With Scag’s Blade Buddy tool, blades can be held more securely.
• The fourth step. The bolt that holds the blade in place must be removed by removing the nut.
• The fifth. Remove the cutter blade, bolt, and spacer from the spindle shaft. If you want to remove the blade bolt from the spindle, you’ll need to raise the front of the mower slightly.

What lawn mower blade size should I use?

Sizing your lawn mower blade involves checking the length, width, and location of the center hole. When choosing the right lawn mower blade for your mower, keep in mind the distance between the outer holes and the thickness. The length of your current blade should be measured diagonally from one tip to the other tip.

Most lawn mower blades are between 16.75 inches and 22 inches long. Even if your original lawn mower blade is 18 inches long, most lawn mowers can accommodate 21-inch blades. It is not recommended to install blades that are smaller or shorter than the originals.

BEFORE MAINTENANCE, PREPARE THE FACILITY

Make sure you are properly prepared before starting any maintenance on your Scag mower. To ensure your safety, make sure you:

• Ensure that you wear the appropriate protective gear, including gloves, safety glasses, and boots.
• In an open area, park the mower on level ground.
• The parking brake should be engaged.
• If you need to work on the blades, use jack stands to provide proper support.
• Remove the mower’s keys to prevent accidental starts.

When Should Mower Blades Be Sharpened?

To decide when to sharpen your blades, it is recommended that you do so about every 20 to 25 hours. The frequency with which you mow and the length of time it takes you to complete the task determines the frequency with which you need to sharpen your blades. Repeat this process five to ten times before you need to replace your blades. You can extend the lifespan of your blades even more with high-quality blades!
