I purchased the kit for my 60" bx deck, due to the amount of hay the mower was making.
The kit consisted of 2 baffle "plates" for the upper part of the deck, then an additional left baffle plate, and the 3 blades. I think I had about 300 into the whole deal when I was done.
It was a fairly straightforward install, just required alligning the plates and drilling a few holes. Nothing more than a few hrs to finish.
I am pretty happy with the results. It takes the major volume area out of the picture, and really does a nice job of chopping the clippings. I have ran mine thru some fairly tall stuff, and it just walks right thru.
It isn't a super perfect cut, like some are expecting, but its not hack looking at all. If you dont try to go too fast, it does pretty good. I would like to see more lift from the blades, but gators are always an option there.
I will enclose a few pics of the install, and a chunk of grass I mowed... Posts to follow!
