Today you are going to read the complete How to Change Riding Mower Blades? – An Expert Guide on 2024 [Essential Information]. Now that spring has arrived and the weather is warming up, your grass has also probably is beginning its growing season. So, it’s time to get the lawnmower out of the garage or shed and begin seasonal lawn care. Before beginning your lawn maintenance, you’ll want to get your lawn mower in tip-top shape to facilitate lawn care.

It is fundamental that you verify if your lawnmower blades are sharp enough. This will make it easier to cut your grass and at the same time, reduce the stress on the engine of your lawnmower. It will likely run faster and smoother with new sharp blades.

With sharp blades the health of your lawn will be aided. If the blades are dulled, you won’t get a clean cut. The mower will probably resort to pulling on the grass blades, perhaps tearing them and even damaging roots.

Control your actual blades to see if they need to be sharpened or replaced entirely.  If there is wear on the blades or any type of visible damage, you’ll need to change them. If you change your blades, you’ll be doing your lawn and your mower a favor.

Here is the Process of How to Change Riding Mower Blades

Move your mower onto a flat surface, asphalted or concrete, and park the mower. Turn your mower off and lock the brakes so that it cannot move. If necessary, block the wheels as well.

Locate the spark plugs and disconnect them. The spark plug wire must not be on the plug to prevent an undesired ascension of the engine.

You now need to raise the lawnmower deck to its highest level. With the mower raised you will achieve the best access to the blades.

It is necessary to raise the entire lawnmower now so that you have enough space to use tools underneath the mower.

Since a riding lawnmower is a heavy piece of machinery, you will need to raise it and block it so that there is no risk of it falling while you are working.

Concrete blocks, large solid pieces of wood, or anything that offers no risk of breakage, or movement might be used to prop it up. However, for the maximum amount of safety, a tractor lift, or a mower lift are the ideal tools for raising your mower.

Place the mower or tractor jack into place on the surface. Many mower jacks will have a strap to connect to the outside tire. Secure the strap and use the jack pump to lift the mower into position.

Use a wrench, that is the correct size, to remove the mandrel bolt or nut on your lawnmower. You may need to block the blades so that they don’t turn while you are removing the bolt. A cheater pipe is one option for blocking the blades.

With the correct wrench, turn the bolt counterclockwise until you can remove the bolt from the shaft. Now the blade should drop off.

Should your blade seem to be blocked on the shaft, you may need to pry it off or work it back and forth a bit until you have loosened it enough to slide it off.

If you have not already acquired the new blades for your lawnmower, you can take one of the old blades to a lawnmower supplier or a hardware store and find compatible blades to install. Many mowers only use one long single blade while other models use two. Each brand and manufacturer will have a specific design.

Make sure to consider features the blades may have when purchasing and select blades that best meet your lawn care needs. Some examples include heavy-duty blades or mulching blades.

Consider what’s available and what is best for your lawn. When selecting your new blades, make sure they match the details, the length, offset, etc. should match to fit correctly on your mower.

Now place the new blades onto your mower. Look to see if you have placed the blade with the correct side up. If the blades feature an offset, the center will be positioned higher up than the blade ends.

The blade must fit completely onto the spline. This is necessary for you to ensure that the new blades will not incur damage when the bolts to secure them are tightened. Also, you can visit How to Remove Deck from Craftsman Riding Lawn mower

Finally, tighten the bolts that will secure your blades into place on the mower. Your lawnmower may come with specific torque indications from the manufacturer.

Take advantage of the fact that you have raised the mower to check out the rest of the deck and its parts like belts, tensioners, pulleys, or any other important parts. Now lubricate any parts of your mower that have grease fittings, especially the mandrel bearings.

Once you have finished with lubrication, slowly lower your mower from its raised position with extreme care, especially if you have used blocks or various materials that it is raised up onto and if you have used something other than a mower or tractor lift to raise it from the surface you are working on. This movement will be much easier and safer if you are using a tractor or mower lift.

Some Final Considerations

If your model of lawnmower has two blades and you are replacing one blade, you should be replacing both for a cleaner, smoother cut. Make sure the pulley does not turn when you are turning the bolt to loosen it.

If necessary, get someone to hold the pulley still with grips or locks but never use your hands to avoid accidents. You can also block blades from turning by placing a wood block between the deck and the blade while you are loosening the bolt.
