There's been a bit of a change in regards to the anti-blow out baffles. After several months of testing with a few different configurations we've decided that due to the varied conditions through out the U.S. and Canada we would introduce a 2nd baffle type.
In our testing a second baffle called a "lip" baffle performed very well in many of the southern grasses. The "anti-blow out" baffle actually performed better on the northern grasses especially in dry conditions such as fall and during leaf removal season. For this reason we moved the "lip" baffle into production ahead of the anti-blow out baffle. This allows us to get the baffles needed down south to market where it may be utilized sooner.
Both baffles will help with leaves. The "lip" baffle is pictured above and the "anti-blow out" baffle will simply lower the bottom edge of the flow control baffle (std. on all current decks) by about 1/2".
I think its probably important to know what the baffle benefits and what it may hurt.
The baffle is great for thin sparse grass or in dry conditions and leaf clean up when dust and chasing leaves can be an issue. In these applications it will generally improve the quality of cut. In some cases rather significantly.
On the other hand Fred, who did most of the testing of the baffle, tells me that in thick lush lawns the baffle may actually hurt cut quality.
As long as you use the baffle as it is intended you should be in good shape.
