I bought a new X300 and the 42 inch mulching kit a few weeks ago.
The installation manual for the mulching kit states that it is very important to only use the mulching blades provided with the kit. However, the mulching blades look exactly the same as the blades already on the mower deck.
Just wondering if it is really necessary to replace the blades or if I can just keep the new blades for use after the current ones wear out. All of this is new to me as I only recently moved out to the country and never had to use anything but a push mower before.
