Which Way Do Mulching Blade GO ON?

Mulching blades vary somewhat from regular lawnmower blades. You can choose from the following techniques to determine which way mulching blades go on and which way it should be fitted.

Design and Metal Flaps

The mulching blade has a bend in its shape or design. You’ll see that the blade is flat in the center and gradually curls up to the edges. While other brands’ bends may not be very noticeable, they do have what appear to be metal flaps that were carved into the back of the blade and twisted upward.

Blade components known as edges, wings, or bevels may also be referred to as metal flaps. Some mulching blades have serrated teeth and a sharpened edge on these components. Following the installation of the blade, the points of those wings or the bend’s protrusion must face the interior of the mowing deck.

Cutting EDGE

Recognizing the mower’s cutting edge is the most accurate and efficient way to determine whether the blade is up. Particularly when contrasted to the duller side, this edge will be significantly sharpened. Given that it will be chopping grass, the cutting edge should really be facing the grass. Tapers should also be present on the blade’s ends. If the blade is positioned correctly, this ought to point upward.

Cutting edges cannot always be switched out. In actuality, they shouldn’t be utilized in a lawnmower unless such center hole and length of the instruments are the same measurements as the original one. On a mower, using the incorrect blade might result in a whole new set of performance problems. Mower blade edges frequently deteriorate over time, growing dull and decreasing cutting capacity. Be sure to maintain your blades sharp to prevent a bumpy lawn.

Changing Crank Shift Direction

Verify the mower’s shaft’s direction of rotation. Where you attach your blade is on the crank shaft.

The simplest way to verify is to switch off your lawnmower and partially pull the “Starter Pull Cord” to see how the shaft travels. Since the shaft moves predominantly clockwise, the sharp edge should be towards the direction of shaft motion.

The shaft and blade will both rotate in a clockwise direction when you look at the rotary motion from the drainage chute, which is located on the correct side of your mower’s deck.

Model Number

This approach, in contrast, works much better at determining which direction a mulching blade is moving. Look at the blade‘s two sides and check the bottom for a model number or the term “bottom,” which may be imprinted there. Whether it is a word or a number, the written side must be towards the ground when it is installed.

Wobble Test

The wobbling test is the last step to ensure that blades are stable in the mower after they have been adjusted or replaced. This quick stress test will show you how well your blade will efficiently mow and if it is prone to falling out while you are using it.

Hold the mower blade in one hand while holding the deck in the other .  Gently drag the blade down by giving it a tug. If the blade is on the proper side and the sharp edge is towards the ground, it shouldn’t sway. Make sure that it is on the blade shaft if it wobbles. You may accomplish this by using a wrench to tighten the fastening bolt.

Your lawnmower blade will indeed be safe and ready to use after the wobbling test is finished. Reposition your lawnmower’s wheels, and you’re ready to go.

Check Bevel

Last but not least, look at the bevel, which is a component of the cutting edge of the mulching blade. The component that really cuts is the bevel. When the lawnmower is in its vertical mowing position, it should be on the top of the blades or the side that will be looking away from the ground.

What Happens When You Place Your Blade Incorrectly?

The incorrect mounting of your lawn mower blade may harm both your mower and your grass. Blades are designed to be used on a specific side and using them on the incorrect side frequently causes internal mower damage.

Mowers that do their job well leave lawns appearing tidy or even, much like a new haircut. The grass is cut inconsistently when the blade is mounted backward because there is no sharp edge to cut the grass. It is essential to position the mower blade on the correct side unless you love choppy, untidy grass.

In addition, problems with the system may arise when a section of a working machine is looking in the wrong direction. In this instance, harm may manifest itself in a number of ways. For instance, damage to the structure to the mower’s bottom, blade damage, and decreased overall lawnmower effectiveness.


As a conclusion, whichever approach you select from the above list to determine which way the mulching blade go on, the mulching blade should be fitted so that the cutting edge should be installed downward or facing the ground and the flaps or teeth edge should be upward or facing the deck after fitting. Above importantly, keep in mind that a lovely lawn doesn’t just appear.
