I just bought a 18/38 with mulching kit. I do not think it is a differnt set of blades. What it looks like to me is a plastic/metal skirt on the leading edge of the deck
and then it flares up and covers the discharge chute. The chute deflector stays attached. Appears to be held on by 4 bolts and nuts. I just recently had a knee replacement however if I was not still hobbling around I think I could put the puppy on myself.

I installed a mulch kit on my Broadmoor, It was a plug, baffles and three blades.

The plug and baffles bolt onto the deck through existing holes. The blades did not appear to be any different than the originals.

It's not to hard to install...it takes a little patience lining everything up and getting them bolted on. I think anyone that's capable of taking off the deck and changing a blade could install the mulch kit easily.

I'm satisfied with the mulch kit's performance.
