Gator 3-in-1 Mulching Lawn Mower BladesMade of strengthened steel

If you are looking for blades that will do an excellent job at cutting your grass and mulching it up, you are going to be home and dry with the Gator 3-In-1 Mulching Lawn Mower Blades which are built for performance.

Key features

  • Works as a 3-in-1 blade
  • Made using hardened steel
  • Austemper treated for extra strength
  • Each has a length of 17 3/8 inches

Oregon has been one of the largest industry players for a long time, and they are counted among the most reliable companies where mulching blades and other equipment are concerned. Strength, performance and durability are largely what they are known for, and the Gator 3-In-1 Mulching Lawn Mower Blades do not fall short of expectation.

For starters, they work as 3-in-1 blades that can deliver three functions. The first is grass cutting and clipping, and the other is bagging. Perhaps what they are mostly known for is the mulching function that allows them to put back the grass clippings into the lawn to decompose and act as manure.

For this reason, they are made with teeth that are jagged and that are curved upwards, a characteristic that allows for the clippings to be cut to a fine consistency. In addition, they are jagged, allowing for a larger cutting surface area so that you can cut larger surfaces faster.

Strength is also one of this blades’ features, and they are austemper treated for this reason. This makes the steel on them so much stronger and tougher, allowing them to cut through tough grass, twigs and stems with a good deal of ease.

Seeing as they are quite heavy, your Cub Cadet would need to be a high powered one. Low power mowers find it difficult to spin the blades, resulting in slow speed and low momentum. You may also cause an unnecessary strain on the mower if they are too heavy.


  • Come with 3-in-1 function
  • They are strong and durable
  • They come as a set of three
  • The edges are serrated and also curved upwards


  • These blades are heavy, making them ideal for lower power mowers


Mulching is an exercise that is heavily dependent on the strength and integrity of a blade, and the Gator 3-In-1 Mulching Lawn Mower Blades are well equipped to handle the job. Seeing as they come as a set of three, they can be used on a riding mower that has a wide mowing deck.

What I like most about these blades is the fact that they come already sharpened, meaning that you will have no need to sharpen them yourself.

On the down size, this blade is not suitable to use in wet conditions, and this is largely because it makes extremely fine clippings of the grass. When mixed with rain water, these clippings make a pulpy mess that can be hard to mulch and get rid of. For this reason, you might want to find replacement blades that can be able to work in the rainy season, and save these for those drier conditions and for thicker vegetation.


  • Made to be strong and hardy
  • Comes already sharpened
  • Ideal for extremely thick vegetation
  • Has a large cutting surface

Build Material

Mulching is a labor intensive activity, and it calls for tools that are strong and durable. Be certain to get blades that are made using strong material that will allow them to work without sustaining damage easily.

Type of serration

A serrated blade that has upward turned edges makes for a better tool since it creates a larger cutting surface area. Flatter blades are unable to do as good a job.
