  • Comes with sharp cutting edges
  • Suck up grass very well and mulches them
  • The output is much smaller pieces of leaves
  • High quality steel material manufactured in USA
Cons
  • Can’t be used for bagging

Maxpower mulching mower blades are awesome when it comes to using your mower at variable settings to mulch both grass and leaves especially in the case of Husqvarna mowers.

Notably, the curvy wings of these blades are what convert the leaves into dust. The mulched pieces of leaves are much smaller which decompose easily into the grass and add nutrients to the lawn.

The robust design of these blades cuts the grass in such a way that it hits the cutting edge, again and again, this way it is converted into small pieces.

The body of these blades is made to suck up grass firmly just like a barber is giving a haircut. It holds the blades tightly in the upright position and then cuts them into pieces in a repetitive circular motion.

Markedly, the compatibility of these blades with the shaft of the mower is also great, especially for 42-inch deck-size mowers. It has a five-star hole that makes it easy for the blade to mount on many mowers.

Additionally, the cutting edge is made of high-quality metal that is sharp and long-lasting. You won’t need to sharpen them right after the purchase.

Most importantly, the installation and sturdiness of these blades are great. They are easy to install and sturdy enough to counter any stress during mowing.

One noticeable thing to mention here is that they aren’t high lift or bagging types which means you can skip them if you don’t want to mulch. Because you can either do mulching or bagging at one time using any lawnmower.


Oregon G5 Gator Mulcher Blade for MTD and Cub Cadet Mowers

9.5/10 Avg. Score

Pros

  • Extended cutting edge to mulch effectively
  • Repetitively cuts the leaves and grass
  • Good suction power
  • Thick and long-lasting material
  • Easy to install on spindle
Cons
  • A bit heavy, engine must be in good condition to work with this blade

The best thing I observed about this Oregon G5 mulcher blade is the cutting edge which is made of fused tungsten carbide material. Additionally, it is extended than normal on the body of the blade.

An extended cutting edge means the overall blade will have more cutting area than it does normally.

It helps the mower to come in contact with leaves or grass more frequently which results in much smaller pieces of leaves coming out of your mower.

Another thing about this Oregon G5 mulcher blade is its sharpness.

Please note that a mower’s blade doesn’t have to be razor-sharp. These mulcher blades are sharp enough to cut any shoots coming on their way.

Uniquely, the perfect width and length make it better to mulch leaves in just two passe using your MTD or Cub Cadet.

If you are mowing on hard soil or some thick plant shoots these blades won’t bend. Instead, they will serve the purpose due to the high-quality metal they are built with.

The metal is thick which makes these blades a bit heavy. You may observe a little more noise from the engine but that’s what a true Gator sounds like right!

Instead of five, these blades are six stars which makes them the perfect fit for many mowers.

Try to use a mulch plug if your mower substrate (spindle) allows it, it will make the fitment easy.

Mowing on in a thicker grass field these blades works equally as they do on mulching leaves.

Lastly, I would say these blades are by far durable material in the market yet keeping their performance output more than 80%.

But this blade has a bow-tie hole which is made for easy fitment on many mowers.

Unlike other blades, the design of this blade is also different in the way that it has broader curvy metal flaps.

Together with great mulching performance, this blade also improves your wash port because this blade mulch leaves to much smaller pieces, so you don’t have any clumps attaching to the mower deck or chute.

Compared to the earlier G5 mention, this blade is good at high lift which means you can also use them for bagging leaves or grass.

The corner of these blades where the serrated teeth are located are broader that keeping the grass into play. These corners help anything coming towards them in a rotational motion so the cutting edge can do their work.

More to mention about the metal fins of these blades that must be towards the deck. After installation, you will clearly observe less noise, smooth engine running, and the magic of the fins that suck up grass like a vacuum.

Noticeably, these blades are wider, thicker, and longer which is the heredity trait that these blades get from Gator blades.

Being nice and sharp material, these blades really chop up leaves into dust on your lawn.
