Right now (2000, P216012 HiVac), I have the Ninja Blade with the bag shoot attached, but it has the plug in it. I do push over grass, so I have to actually make two passes (St Augustine) each time to get 100% cut. As stated in previous post, I am replacing the 6.0 Briggs with the Honda, going to leave everything else equal so that I can compare. Then l'll remove the bag shoot and install the mulch cover, then I'll swap the ninja blade for the 99-121 I just ordered. One change at a time.
(The Briggs has a knocking rod after 20years so I just wanted to try a Honda)
