Dropped the blades off my LT1-46 to get ready for the fall leaf mulching season and I find the blades now have an "S" notch for the spindle instead of a star pattern.

A search for my usual Gator blades comes up short. Looking like it's back to the factory blades.

Has anyone else found any aftermarket blades yet?

Thanks! Now are they actually a better harder blade too? Because if mine are like the ones on the brothers 2020 ZT2 50in, they were soft as butter. The Oregon I put on my old mower still look new at 100hrs

For a ZT1 54 I wore out the oem blades in a little of 4 hours. The costs for S blades I looked at were around $90 a set.
Then I researched converting to Star from S as for price and availability in my area.
3 spindles that are exact size match, shaft, pulley size, and bolt pattern. under 70$ (see below) a set of 6 point star compatable to MTD $33
