Husqvarna Clear Cut Fabricated Deck Mulch Kit, 54 in.

Note: My first and only use of the mulch kit so far was on fallen leaves, not mowing grass. Before swapping blades, I used the discharge plug by itself first. It was easy enough to install and covers most of the opening. The design could fit the opening better, there's a narrow space that's open; it's covered to some degree when you close the discharge flap on top. As I was mulching leaves I could easily see what did/didn't get cut. I slowed the speed down considerably and (as expected) made two passes in most areas. See pictures to get an idea of how much leaf liter was on the ground. I then switched blades, installing the ones that came with the kit and mowed again a few days later. I noticed some improvement but not a lot. Same thing, mowed slow and made additional passes as needed. Final note: This review is based on mulching leaves, not grass. I would anticipate better results with a dry lawn and when the grass isn't too tall. Let's remember the mower deck on most lawn tractors isn't designed to mulch so any positive results is a bonus.

Does not fit exactly and their is a slot on the top that let cut grass fly all over me when I mow.

This fit perfect one the Z254 with the solid steel deck.

I bought the mulcing kit when I bought my mower. Dealer installed it and I use it every Fall. We are surrounded by woods so we get plenty of lfeaves. It turns the leaves into fine debris. The kit comes with mulching blades, a cover for the dischrage chute, and a plate that goes under the deck that helps pull the leaves up and into the blades.
