The kit is a plastic plug and 3 blades. The install was OK, though it takes some fiddling around to get the peg to fit up that holds the front part of the plug. I didn’t switch out the blades and will do so when the others wear out. Seemed to mow just fine.
Easy to install just use the carriage bolt and nut with a washer to help hold it in place. Works very well on dry grass. No signs of clippings at all. Works well on the wet lawn. Just leaves some clumps when you stop. very happy with this purchase.
