RCK48-15BX MMM Mulching Kit ?

Hello there, new guy here.

Hoping someone could help me out, I am looking for a Mulching Kit(if there ever was such a thing)for my RCK48-15BX MMM.

Any help would be appreciated.

So far I have been using regular blades with the side discharge and have been satisfied, except for having to avoid discharging the grass into the flower beds and having to go back over a few heavier buildups of visible clippings in the yard.

Maybe when fall comes and I have to mow over the leaves I will find the side discharge and regular blades wont do anymore ?

FWIW, mulching blades that fit my deck seem to be readily available and I could make my own discharge block off plate if necessary.

I have seen pics(like below)and info on kits available for other decks/models but not my RCK48-15BX.





Thanks for your time, below is a pic of my tractor/BX1500.

Thanks for the pics etc.

I wound up ordering 70000-72900 which came with 70000-25040 blades.

Took under a week to get, and a hour or two to install.

Ran the mower to make sure it sounded good.

Will try and mow some grass next week.

Peace.

A few more pics.
