“Set up for mulching” That’s they key. True mulching blades are matched to the mulching baffles. That’s why they are sold in kits. Many people overthink things. They hear this and that about Gator style blades, buy them and expect them to perform better than the OEM mulchers. G5 and G6 Gator are high lift and will clog a mulching kit. The G3 is a standard lift blade. Oregon clearly states that Gator blades are for bagging and side discharge.For the last thirty years, since I move into a new house in 1993, I’ve had the same Toro tractor and two Toro Super Recycler mowers. These mowers have all been setup for mulching since day one and do a great job. Two things will cause me problems, but it is my own fault and nothing works 100% of the time. Having to cut when the grass is wet and cutting the grass when it is too long. Sometimes you have to do just that and you live with it for a week. I’ve sold the Super Recycler mowers to two neighbors and at least 2 dozen relatives or personal friends. Not one of them has been displeased with their purchase and one neighbor even got his brother-in-law to purchase one also. Everyone mulches or bags in the fall. Only thing that you must do is keep the underside of the deck clean and blade sharp.
The mulching blades sold with the kits are typically a low lift blade. There is just enough lift to keep the grass suspended for multiple cuts. That’s where the wavy blade design pays off.
A mulching kit isn’t going to perform well on tall or wet grass.
Side discharge with a Gator G5 or G6 in tall or wet grass isn’t going to perform well either. They make a soupy or clumpy mess. A Gator G3 and side discharge is going to give better performance. However, an OEM standard lift or high lift is going to work best for side discharge in all mowing conditions. The same goes for aftermarket standard or high lift blade.
