 Factors to Consider When Purchasing the Best Mulching Blades

When looking for mulching blades, you should have a clue of the product that you are looking forward to working with on your riding or push mower. Here are some of the factors to put in consideration.

  • Number of pieces

In case you are looking to upgrade the blades on your riding mower, then you have to buy a kit with the correct number of blades. Most riding mowers have two to three blades, and all should be replaced with identical blades for maximum mulching performance.

There are two reasons why you shouldn’t replace only one mulching blade.

     1. Mulching blades are much heavier compared to standard blades, therefore installing blades with different weight blades will interfere with the mower’s output. One blade tends to be run slower than the other. This can result in disordered mowing and unpleasant experience for the user.

2.You won’t see the advantage of better mulching or airflow, as the standard blades will still bring about clumping.

  • Length of the mulching blade

Having the right length mulching blade for your mower is important. Mowers and all of their constitutes are drafted particularly for a specific length of the blade. Installing a very-small blade will provide less than maximum results in three ways:

1.Your bagger will be inefficient because of the lack of airflow that a small blade provides.

2. you will have work extra hard because the cutting area your mower can cover is smaller.

3. For multi-blade mower decks, you will be missing small strips of grass altogether, the lawn will end up looking like a mosh pit with several Mohawk haircuts.

On the other hand, very large blades will slow your mower down in case they even fit under the deck. You are might cause more clumping as well due to the lack of space under the deck that the larger blade creates also because of the slower speed of the mower. Furthermore, a very long blade can be dangerous.

The good thing is most lawnmowers label their cut size on the side of the mower, so check your model first before purchasing the right length and the best mulching blades for your mower. The other option is referring to the owner’s manual under the replacement parts area.

  • The durability of the mulching blades

Mulching blades happen to be more durable than standard mowing blades because of their design and thickness. That is for commercial machines with belt-driven decks and riding mowers. However, push-mowers with direct-drive shafts have a durability issue. Here’s why:

  1. For belt-driven decks, blades are normally attached to spindles, which are then fastened to pulleys. A belt links all the pulleys while also being fastened to the drive pulley on the motor. When a thick mulching blade hits an object, it will probably slip a bit on the belt. The blade may bend, but the mower itself will be intact.
  2. For direct-drive mowers, like standard push mowers, blades are attached directly to the mower’s output shaft without a pulley or belt. This allows the smaller motor to spin the blade very fast, but it does not provide any fail-safe competence. A standard blade will bend if it hits a rock, leaving the mower undamaged.
  • The weight of the mulching blades

Mulching blades are heavier than standard mower blades. They are thicker, and the design of the more hostile lift angle needs more material by default. Due to this, they may cause your mower to run slower. Mower users with older riding mowers may find that their mower wants to stop when engaging the deck. The accelerated inertia of the mulching blades provides more defiance than the mower was drafted for.

While this is an essential evil in the mulching process, you may evade blade-induced bogging if you halt the mower before engaging the cutting deck. This will decrease the amount of strain on the engine and eventually, the blades will be up to speed, the machine should function without sputter or complaint.

  • Mounting options of the mulching blades

There are different mounting hole styles on the current’s mowers. The most common ones are the six-point star, universal fit, bow-tie, and five-point star. The part where the blade attaches under the mower deck is drafted for one of the shapes we have listed above. The installation is easy if the blades match the spindle (where the blade attaches). The simplest installation methods happen to be the five-point and six-point stars, as they just require the user to detach one bolt. However, universal kits are not consistently the best choice since they are not drafted specifically for any particular mower, but they do take the assumption out of which blade is appropriate for your mower.

  • Value of your money

Although the cost of the mulching blades should be the last thing to consider, it is good to purchase the product that is worth the value of your money. Some mulching blades can be priced so high but when it comes to performance, you end up being disappointed. However, there are those mulching blades that are rightly priced and the performance is worth it. Therefore, you should make the right decision.

Conclusion

 A well-maintained lawn is necessary for a beautiful looking home. If you wish to make your lawn look decent and neat, then you need to apply the process of mulching to spread fine debris and grass cuttings again into the lawn. This will add a protective layer to the lawn. Furthermore, having the best mulching blades will make your lawn mowing experience much more effective as well as ensure great growth across your lawn.
