There are various standards that determine the performance of a lawn mower, and the blade it uses is among them.
Different blades come in various sharpness and shapes, and they will be a major factor in how you cut your grass. The most common blades are mulching and regular blades, which cut grass in different ways.
Mulching Blade vs. Regular Blade – Comparison table
| Mulching Blade | Regular Blade | |
|---|---|---|
| Shape | Curved shape with plenty of bends | Straight edges |
| Airflow promotion | Move air in a circular form, with some pushing the clippings out and the other keeping them in the deck for cutting | Straight airflow that pushes the clippings for cutting and then discharge |
| Functionality | 3-in-1, so they can work for mulching, bagging, and discharge | 2-in-1, so they work for bagging and discharge |
Mulching Blade vs. Regular Blade – How they compare
The main difference between these two blades is their shape; regular blades have straight edges while mulching blades have curved ones. The curved edges serve to increase its cutting surface area, as well as keeping the clippings within the lower deck of the mower. In turn, the blades will cut the clippings further until they seem to ‘disappear’, as the clippings are in very small pieces that are perfect for mulching.
The other difference is in their functionality. While mulching blades promote mulching through their processing of the grass clippings, regular blades will aim to generate lifting of the grass blades into the deck, cut them, then fling them to the discharge area. This leads to their other name which you may hear of, the ‘high lift blade’.
Due to the differences in their design and functionality, mulching blades are meant to prioritize keeping the clippings under the mower, so they will not be as efficient when handling bagging or discharge tasks. The regular blades will be great at bagging and discharge, but they cannot cut the clippings into smaller pieces like mulching blades do. Instead, their blade design allows massive air volumes to pass through the cutting deck, which promotes highly efficient grass discharge.
Mulching Blade vs. Regular Blade – A comparison review
Mulching Blade
Pros
- They are very effective at cutting grass into very small pieces
- Achieve and promote natural fertilization
- They do not have high energy demands, so environmentally friendly
- Make the space cleaner
Cons
- Less efficient in discharging grass clippings
- Unsuitable for tall grasses
Regular Blade
Pros
- It is an efficient discharge method
- It is good for tall grass management
- Easy to replace it with mulching blades
- Lower chances of clogging in the deck
Cons
- You cannot use them in dusty conditions
- They require higher power demands, so you cannot use them often
Verdict: So, which is better? Mulching Blade or Regular Blade?
Mulching blades are the overall winner of this comparison, due to their lower power demands and multipurpose usage. You can use regular blades though if you want to manage taller grass, or if you manage your lawn on an occasional basis.
FAQs
Can I use mulching blades without a mulching kit?
Yes, you do not need a mulching kit to use mulching blades, although it is advisable for the best results.
