There are different types of mowing blades, and each one of them uses a different mode to cut the grass. Some of the most common blade types are the standard blades which are also called deck blades. There are also reel/cylinder blades, lifting blades and mulching blades. The G3 and G6 are special types of blades called Gator blades, hence their name. These work by combining features from lifting and mulching blades. This way, they deliver optimal efficiency.

The Gator G3 has the capacity to work on lawns that have debris such as twigs from trees, roots and lumps of soil. Aside from this, this blade is an all-weather device that cuts grass even when it is wet. The ends of the blade have ‘teeth’ to be able to lift the grass off the ground so as to perform a cleaner cut. Owing to the sharpness and volume of this blade, it is able to rotate really fast and cut the grass to really small pieces. This way, you do not have to bag it up as the mower spreads it across the lawn to act as manure for the remaining grass.

The Gator G6 uses a similar principle as the Gator G3. However, this blade is able to work in much tougher conditions. Often times, it is used on riding mowers and it has the capacity to fit a 36 inch and 54 inch cutting deck. This blade is better suited for commercial applications, especially in areas that are quite expansive and that have irregular terrain. The Gator G6 can cut through tough grass, wet grass, lawns with a lot of debris and even sandy regions.

The Gator G6 is able to handle tougher terrain than the Gator G3, making it the better blade.
