Just what are the perks you can expect to experience if you install a mulching blade on your mower? Here are a few of the main ones. Why? Well, mulching involves cutting the clippings much finer, and the longer cutting edge helps the blade to accomplish this. The actual cutting edge on a mulching blade is quite a bit longer vs a high lift blade. This is another noticeable difference between mulching blades and high lift blades. This part of the blade is responsible for generating the lift the steeper the curve, the greater the lift generated. Both are curved upwards (as mentioned, this is how the “lift” effect is created), but this curve on a mulching blade is much more gentle, while on a high lift blade, it’s a much steeper curve. When looking at mulching blades vs high lift blades, you’ll notice a pretty big difference on the back edge of the blade. A High lift blade by contrast is typically very straight on the cutting edge side, as it’s designed to be as aerodynamic as possible to generate the “lift”. This also increases the surface area of the cutting part of the blade to aid in the mulching process. Curved Blade vs StraightĪ mulching blade is more curved in its design, as this helps to generate the increased deck circulation required for mulching. If you were to compare a mulching blade vs high lift blade side by side, here are the differences that you’d notice right away. Mulching Blades vs High Lift Blades: What’s the Difference? A high lift blade features a much more severe upward curve that generates more suction in the deck and enables the clippings to be discharged from the deck with more force. What differs between the 3 variations is the angle of that curve. You see, within the 2-in-1 category, you have regular blades (which offer medium lift), as well as low lift blades, and then high lift blades.Īll of these different variations have the same basic design that features a curved back edge, which is what creates the “lift”. But it’s the “high lift” that differentiates them from other types of mower blades. Your options are limited to either bagging clippings or discharging them, hence why they’re known as 2-in-1 blades. High lift blades CANNOT offer you the mulching function.
“ What are high lift blades and do they allow you to mulch?” is what I asked the local mower shop owner many years ago. Related Article: Can You Put a Mulching Blade on Any Mower? An Overview of High Lift Blades It features a curved blade to encourage increased circulation of grass clippings in the cutting deck, and a longer blade edge to cut them into a fine mulch. And it’s that last function that its design is (unsurprisingly) geared towards. You can bag your clippings, discharge them or mulch them. 8 Mulching Blades vs High Lift Blades: Summing It Up A Bit About Mulching BladesĪ mulching blade is also known as a 3-in-1 blade because it offers you 3 different cutting functions.
