Husqvarna Mulch Deck Cover, 42 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.

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.

Works great! For my needs I completely removed the stock spring loaded chute before installing the kit. And, as suggested by somebody in a previous review, I installed a strip of self-adhesive 3/8" thick foam weatherstripping to the back edge of the new cover where it meets the deck, sealing it to the deck to prevent any of the cuttings from blowing out. I drilled that edge about midway so I could install a 1//3" self-tapping screw to ensure the seal is tight. This is a HUGE improvement! Without the seal, small amounts trimmings escape and settle in among the pulleys and towers and whatnot, eventually building up enough to be problematic. But that simple tip makes a great difference. Perhaps the manufacturer will include a seal with the kit. Overall, I'm very satisfied with the results!
