The Major Differences Between Mulching Blades And High Lift Blades?

Mulching blades have been designed for chopping down grass pieces into mulch, while high lift blades tend to eject the cut grass pieces out of the chute or into a collection bag. They are the best blades when it comes to cutting grass that is wet or too tall without clogging the lawn mower.

Mulching-type blades were designed to be more curved to mulch grass pieces finely. It also circulates the cut pieces around the deck so they get chopped down. In comparison, a high lift type blade is rather straight-edged because its purpose is to create suction for forcefully ejecting cut grass. Its blade does become deeply curved at the end.

One crystal clear way of distinguishing between the blades is how their back edge slants upwards. In a mulching-type blade, the curve at the end of the back edge is very smooth and gentle, whereas there are two such curves on either side of the back edge in lift-type blades. These curves are commonly referred to as wings and are responsible for directing the air pressure upwards. 

Specs Regarding Mulching Blades

The specs that distinguish mulching blades are the three-in-one cutting blades, the ability to mulch the grass that is cut, and to fertilize the lawn, too. These blades also need low power, and they are eco-friendly ones that don’t harm the environment.

These blades can cut grass, convert it to mulch and then either spread it on the lawn or collect it in a bag. You can run these blades on low power and fertilize the lawn. A blade designed for mulching is naturally longer when its deeply curved shape is considered. This is necessary to facilitate its purpose of chopping grass even after it has been cut. 

– A Three In One Cutting 

Mulching-type blades were designed to be a better and more useful version of the regular blades used by the mowers, the way that they have three in one blades, is something that is unique and a known trait to signify them. You can cut the grass or convert it to mulch with these blades and even bag them after mulching. 

So, you can convert the grass into mulch as you mow and have it spread across the lawn. Alternatively, you can collect the mulched grass and use it someplace else, like a compost bin. Performing a three-in-one function is why these blades provide a much better cutting efficiency and speed than any other blade.

This takes a lot of time, and the result still needs to be better than that from a blade. This blade is for you if you want to collect ready-made mulch without working for it. 

Mulch created by mower blades is much finer and better than that created by hand. Being so small, it decomposes faster and acts as a rapid source of natural fertilizer for grass. When added to the compost bin, it acts as the perfect source of nutrients for the greens component of the pile.

– Ability To Fertilize The Lawn

This is the only blade that allows double lawn care in the form of mowing and fertilizing simultaneously. With the mulch as you go setting in place, you convert the mowed grass into mulch and then spread it all over the lawn on the move, this, on its own, is a matter of fertilizing. 

A mower distributes clippings in the lawn in such an even and fine manner that we never could by hand. The mulched grass clippings over the grass then act as a form of fertilizer that then breaks down rapidly to give food to the soil. 

– Need Low Power

You can even attach mulching blades to lawn mowers with lower horsepower and weak engines. Most electric-powered mowers that are in vogue these days fall into this category. 

They cannot provide adequate engine power for high lift or gator blades. These blades will run on relatively lower power, even with a powerful mower like Honda hrx217k5vka, because this is how they are build and this is an amazing feature that they have. The result is that you end up saving power and fuel while also staying environmentally friendly, which is actually less anxiety causing for your work.

With a mulch blade, you can mow your lawn and use those clippings immediately without adding to the landfills.

However, you should remember that almost all people nowadays are too busy to wait for the ideal time to cut the grass, so that you can cut grass under all kinds of circumstances with these blades, basically, the company has looked the matter through and taking it into consideration, they have placed this aspect into hands.

– Provides An Extra Lift To The Grass

Look carefully at your high lift blades and notices the tiny upturned wings on their back edge. A high-lift blade, while longer than standard blades, is shorter than the mulching one because its shape has to be kept straight for aerodynamic purposes.

These wings are responsible for creating the high air flow for which these blades are famous. On the other hand, the air suction that it has is one which would be able to erecting the grass blades and making it easier to cut grass. 

What the air suction does, in addition to its job, is that it has a strong enough to expel the clippings from the mower or within a collection bag. The latter would sum up to the fact that the grass mowed is completely wet or too tall, it will not clog the mower deck.

Sure, they will also run on battery-powered or even low-powered gas engines, but mowers with a lower horsepower will have a hard time running these blades. This will only cause the engine to over-exert itself, along with undue pressure on the mower’s internal machinery. 

You need a strong gasoline-powered engine with much higher horsepower to benefit from high-lift lawn mower blades. Not only will this keep the mower in good condition, but it is the only way to experience these blades in full glory.
