(this is my disclaimer

... I have a 121S, which has the 3-blade set up... so I may be speaking out of my rear in regards to the 122R you guys have, but trying to be helpful... it could be entirely different!)

Yep, I love working on the thing.. but I didn't want to remove the deck, wasn't sure how on quick glance. I have a mower lift due to the black clay soil we have. I clean the underside frequently enough to need a lift.. comes in very handy. For the mulcher kit, make it easy on yourself and lay it out BEFORE you try to install it. You'll notice Kubota made them fit in a certain order... some of the parts 'stair-step' into each other. You'll also notice there are a few predrilled holes in the mower deck that will provide support bolt holes to hold onto the mulch kit.. Good luck!!!
