Which Side Of The Lawn Mower Blade Is Up
The lawnmower is one of the most useful tools for your garden.
But to get the best performance from it, the blades need to be set correctly.
Blades often get blunt with the wear & tear over time, and you have to replace them to get the best performance out of the lawnmower.
After buying the new blades, a question comes in your mind: “which side of the lawn mower blade is up?”
The blade replacement part is confusing for many people.
That’s what this post is all about.
If the blades are installed incorrectly, then they may damage your lawnmower.
Read on, and you will find which side of the blades to keep up.
How To Know Which Side Of The Lawn Mower Blade Is Up?
When you buy new blades for your lawnmower, you want to install them ASAP. Unfortunately, both sides of the lawnmower are not interchangeable because of the way they work.
Figuring out which side of the lawn mower blade is up can help to finish the job faster and ensure that it works efficiently. Before changing blades, make sure that you are following all the safety standards.
Here are steps to determine the correct orientation.
Look For Stickers
The majority of the lawnmowers will have a sticker showing which side of the lawn mower blade is up. Since the blade may seem confusing at first look, these stickers will help you in identification.
Instead of the stickers, some of the models may have words engraved onto the blade.
Just in case your lawnmower doesn’t have stickers or stamps, you can either purchase them or make your own so that you don’t forget which side should be facing up.
If you are going to put your own stickers, be careful with their placement to not come in the way of other parts.
Find The Cutting Edge
Locating the blade’s cutting edge is the most reliable way to recognize which side of the lawn mower blade is up.
The cutting edge will be sharper as compared to the duller side of the blade. As this edge will be chopping the grass, therefore, it should be facing the ground.
Furthermore, one side of the blade will have a tapered edge, and the other side will be flat.
Since the tapered edge side should be facing the sky, that will show the right adjustment.
Check If The Blades Wobble
Now that you have found out which side of the lawn mower blade is up, it is time to perform the wobble test to confirm that the blades are rigid.
This test will tell you whether if the blades are prone to falling out when you mow or not.
For effective mowing, the blades must remain secure in their place.
Here are the steps that you should follow for this test:
- To start with, hold the mower blade in one hand and deck (referred to the part that serves as a kind of shield and protects you from the exposed blade) on the other hand.
- Now tug the blade and smoothly pull it down.
- Now, if the blade is on the right side (sharp edge facing the ground), it should not wobble.
- If the blade wobbles, you have to correct it. There are two possible reasons here. The first one is that the blade is upside down, and the other one is that bolts are loose and you have to tighten them.
After you have completed this test, you will have a secure and ready to use the lawnmower.
Why Keeping Right Side Of The Mower Blade Up Is Important?
Placing your lawn mower’s blade upside down could cause some severe problems. It will damage not only the mower but also the lawn.
It could likely result in making the blades useless and have to replace them again.
Damage To The Lawnmower
The blades of the lawnmower are made by keeping specific orientation in mind. Incorrect installation of the blades could cause unnecessary wear and tear.
Although the amount of damage will be different for each lawnmower depending on its brand and misused period, here are possible damages that could happen:
- Making the blades dull, which results in making it harder to cut the grass
- Wobbling of the blades
- Decline in lawnmowers effectiveness
- Damage to the undercarriage of the lawnmower
After viewing the list of possible damage, it is better to install the blades with proper care.
Otherwise, it could result in expensive repairs, and in the worst cases, you may have to get a new lawnmower.
Damage To The Grass
Apart from damage to the mower, the wrong installation of blades could result in the grass’s uneven cutting.
A correctly working lawnmower will leave your garden clean and level, much like a fresh haircut.
But, upside down installed blades will do the opposite.
Unless you like a messy looking lawn, the best option is to install the blades properly.
The results can be much more damaging if the lawn is mowed repeatedly with a wrongly fitted blade. Your lawn’s grass may get uprooted, or it may have low lying growths, which hinders its development.
Types Of Lawnmower Blades
Although cutting grass may appear to be straightforward, there are various strategies you can use.
Due to this variation, there are different lawnmower blades, with mulching, discharge, and bagging being the main ones.
Most lawnmowers will work with more than one type of blades.
Still, it would be best if you had an understanding of the differences between them.
Make sure to check the manufacturer’s ratings to verify that they are compatible with your mower or not.
Here is a breakdown of three main choices:
- Discharge – Being as the simple model of the blade, it enables the grass pieces to blow out from the mower’s side. Mostly, these blades have a lower angle, which helps them to keep the suction levels low.
- Bagging – These blades are useful when you have a bag attached to the mower. Because of their higher angles, most of the clippings end up in the bag.
- Mulching – If you are not a fan of collecting the clippings after you mow, a mulching blade is a perfect fit for you. It cuts the grass into little pieces, which allows them to fertilize the lawn.
When To Replace Your Lawnmowers Blade
It doesn’t matter which brand lawnmower you have or how often you mow your lawn, over time, your mower’s blades will get worn down.
So here are a few tips that will let you know that you need to change your blades.
- Ripped Tips – With time, your mower’s blades will get dull, making them tear the grass instead of cutting it. So, if you see that the tips of your lawn look ragged, it is the time to change the blades.
- Rough Patches – After mowing, if you see that some spots in your garden look uneven, it shows that there is something wrong with the blades.
- Recommendation Of The Manufacturer – The majority of the manufacturers recommend changing the blades after 25 years. However, this could vary depending on the wear and tear of the blades.
