Which Way Do Mulching Blades Go On: Best Tips And Guide

Mulching mower blades are important in keeping your lawn healthy and looking great, but it can be unclear to know which way to put them on. So, which way do mulching blades go on?

Mulching blades should have a bevel that faces toward the ground. It will ensure they can properly chop leaves and other debris into small pieces.

Our guide will walk you through the process step-by-step, making it easy to get the perfect cut every time.

What Are Mulching Blades?

When it comes to growing a plant, you need to consider many things, such as the type of plant, the climate, and the soil. One other important factor is mulching.

It is an eco-friendly technique that helps dispose of grass clippings and leaves in a way that benefits the plant.

Mulching blades often referred to as 3 in 1 mower blades, are a type of blade that is designed specifically for mulching.

They have enhanced cutting edges and can transport grass clippings toward the deck, where they mow multiple times before dropping back down. This process cuts the lawn and returns vital nutrients to the soil, which the plants can use.

They are an ideal option for lawns that are mowed every three or four days as they provide a consistent and even cut.

However, when used on overgrown grass, they can cause clogs beneath the deck and clumps of grass on the trimmed lawn. So, it is important to keep your lawn well-groomed and only use them when necessary.

If you see your tree grow incorrectly, such as the calathea leaves curling, rattlesnake plant brown spots, or peacock plant leaves turning yellow, it may be a sign of a lack of nutrients.

If you’re looking for a way to improve your plant’s growth, consider using these blades regularly. Mulching is an excellent way to keep your plants healthy and return vital nutrients to the soil.

When it comes to these blades, there are a few things you need to take into consideration before making a purchase.

One of the most important factors is figuring out which way they go on. It may seem like a small detail, but it can make a big difference in the overall performance of your lawn mower.

There are three different methods that you can use to figure out which way mulching blades turn.

Method 1: Check Its Symbols Or Letters

They come in various shapes and sizes, but all have one thing in common–they need to be installed correctly.

You can tell which way they go by checking the symbols or letters embossed on the blade. The side marked “bottom” or has a product number should be facing the ground when the lawnmower is in use.

Method 2: Check Its Shape Design

There are metal flaps at its rear, which are curved upwards. They have a slight upwards curve, and some types have less bend.

When fitted, the flaps’ tips and the bend’s protrusion should face the cutting deck’s interior. It will ensure that they are working properly.

Method 3: Find Its Edge Bevel

To install it correctly on your lawnmower, you must identify its bevel. The slope is responsible for cutting and is located at its edge; it has to face the ground while the lawnmower is in the cutting position.

To find the bevel, examine the cutting edge and look for a slant or angle on this edge. Once you have found it, make sure it points downwards before installing the blade on your lawnmower.

How To Know If Mower Blade Is Upside Down

There are two ways to determine if a mower blade is upside down – by rotating it or observing the cut’s results.

Method 1: Rotate It

If you’re on the right side of the mower, rotate the blade counterclockwise. If you’re mostly on the left side, rotate it clockwise. Its sharp edge should be leading. If it is, then the mower blade is in the correct position. If not, you need to turn it over.

Method 2: Observe The Results Of The Cut

If you’re paying attention when you mow the lawn, you’ll quickly see that the mower blade is turned upside down.

It is because everything is contained within the cut. To get a superior cut, you should use a new or a sharp one in the right position. However, if it is in the wrong way, it will significantly reduce the efficiency of the cut.

If you notice your grass being chopped to bits rather than a neat cut, it’s likely because the blade is oriented incorrectly. It is something you should correct right away!

Installing a mulcher blade on your lawn mower is a great way to add nutrients back into the soil while mowing.

Not only does this help your lawn look healthier, but it can also improve the overall health of your soil over time. Here we will show you how to install it on your lawn mower in just a few simple steps.

Step 1: Prepare The Mower

Before you begin, it’s important to take some safety precautions. First, disconnect the ignition system wire from the ignition system.

Then, flip the lawnmower on its side so you can reach the bottom of the cutting deck. Be sure to keep the carburetor with the air filter component on the top side to avoid oil from seeping in.

Step 2: Inspect The Mulching Blade

Now it’s time to take a look at the blade. When the mower is upright, its edge with the phrase “bottom” or a product code should face the ground.

If there are no markings, you can check its bevel. When placed, the beveled section should point away from the floor. The mulching blade mower must also be bent away from the soil.

Step 3: Attach The Mulching Blade

Now it’s time to attach it to the lawn mower. Start by placing the center hole of the blade over its spindle.

Then, place the washer over it, followed by the nut. Tighten the nut by hand until it is securely in place. You may need to use the accessories provided with the replacement blade.

Step 4: Secure The Blade

To prevent the blade from twisting as you adjust it, insert a small wood block between its tip and the mowing deck’s frame. Wear heavy-duty industrial gloves to protect your hands as you tighten them.

Step 5: Finish Up

To finish, use a ratchet to tighten the nut. The nut is typically 5/8-inch in size. Check that the nut is tight and the blade is not wobbly.

Tighten the nut around 70 to 90-foot pounds if you have a ratchet wrench. Finally, remove the wooden block and turn the mower over. Reconnect the ignition system wire, and you’re all set!

What’s The Difference Between Mulching Blades And Regular Blades?

There are a few main differences between mulching and regular blades.

Firstly, mulching mower blades are designed to cut grass clippings into tiny pieces, while regular ones fling them into the discharge chute.

It is because mulching ones generate a revolving air stream that sends the clippings back toward their body once they’ve been cut, which helps them chop the clippings into progressively smaller bits.

Secondly, mulching lawnmower blades are less efficient in discharge and bagging mode than standard ones because they are designed to hold clippings underneath the mower deck instead of throwing them out immediately.

Finally, regular blades are more likely to block if not properly maintained, while mulching can handle more substantial amounts of grass clippings without issue.

So, a mulching blade is the better option if you’re looking for one that can handle more and chop grass clippings into smaller pieces. A regular one will suffice if you’re looking for a tool to do the job without fuss.

Are Mulching Blades Better?

It depends on your intended use. They may be better when providing a natural fertilizer in the form of mulched grass clippings and leaves.

They also help to absorb soil nutrients and retain them in the leaves, which can benefit plants like striped calathea or grass.

Furthermore, mulching is an eco-friendly technique to dispose of grass clippings, as it helps to return vital nutrients to the soil.

However, when used on overgrown grass, they can cause clogs beneath the deck and clumps of grass on the trimmed lawn. Therefore, it is important to be mindful of how often they are used to avoid potential issues.

Can I Use Mulching Blades With Side Discharge?

You can use them on a side-discharge lawnmower to chop the grass into smaller parts. It is a better approach to delivering the soil with nutrients.

The chopped particles will exit the side discharge and can be collected or allowed to grow on the lawn. When using them, it is important to point the blade of the mower inward, so it does not clump beneath the deck.

Using standard lawnmower blades will be more effective if you have a lot of long grass. Tall grass requires regular ones due to its thickness and unevenness. After cutting the tall grass, sweep it up with a lawn sweeper.
