Yes that model comes up as 2019 model.
Okay that pulled it up showing it using the standard 17.27" blades point center star blades. Now the IPL does not show a mulching plug but the 54" Fab deck plug probably will work and it is PN 631-08129.
What CC show mulching blades are a version of the Oregon Gator blades which cutting edge is easy to sharpen. But I would lean more toward the 3n1 blade PN942-05067 for enclosed operation. Harder to sharpen but not impossible.
