Different Blade Types for Lawn Movers

Mower cutter blades are available in a wide range of forms and sizes. Perhaps you’ve wondered why this is the case. The cause for the size variation certainly doesn’t require much explaining. But, for those who are curious about why their mower cutter blades appear to have been hammered into unrecognizable shapes. Here’s why­- numerous lawnmowers have varied aerodynamic functions and have been intended for varied applications.

What Types of Lawn Mower Cutter Blades Do You Require?

Before delving into the numerous lawn mowers blade types, it’s a good idea to understand how a mower cuts grass in the first place.

A blade must be able to drag the grass up through its cutting path in order to function properly at cutting a fairly flimsy edge of grass. It must also create resistance on both sides of the grass so that the lawnmower blade does not slam the grass back down to the dirt uncut.

To do this, blade producers have taken and modified an aviation design. A lawn mower blade features an upswing at the rear of the blade to pull air up through it, similar to how an airplane wing uses wind resistance to produce lift. The grass then follows, rising up for the blade, with the pressure providing some friction on both ends of the blade. This enables the mower blade to cut.

Various angles of upturn at the rear of the blade, of course, yield particular outcomes, and those results can be better customized for various applications.

Deck or Standard Blades

Standard blades, often known as 2-in-1 blades, are arguably the most commonly used in the lawn trimming game. These blades, for the most part, have an aerodynamic design that puts less pressure on the engine that has to turn them. The cutting edge on its front remains flat, while the back edge has a tiny upturn, resulting in a continuous “suck and cut” movement.

These mower blade types are ideal for side discharge and bagging operations as they provide a lot of lift in one direction.

Low Lift Blades

When you want enough lift for the blades to cut your grass but not enough that your sandy lawn is sucked up into the deck, low lift mower blades will come in handy. Why? Because they have a smaller upswing at the back of the blade, they give less lift than other types of mower cutter blades.

They won’t cut your thicker grass as well as a blade with a lot of lift, but they also don’t stir up as much dust. Furthermore, because they generate less drag, they are gentler on your fuel usage as well as the wear and tear placed on your engine.

High Lift Blades

The high lift mower blade creates significantly greater lift due to a more dramatic upturn at the back of the blade. Because it generates so much lift, this type will require a more powerful engine to function well. It may also cost you a little more in terms of petrol. However, it often produces a superior cut in thicker grasses. It’s an excellent alternative for bagging up your clippings because the increased lifting force can propel the clippings up and out of the deck.
