It's not a wear down, that piece looks like it broke off, it's not a smooth wear surface.Leaves, sticks, even just grass will wear out blades like that in time......2 years is quite a long time for one set of blades! Those Mulch type blades don't have as much material / steel on the "lift" part of the blade to start with so...they will wear out even quicker!
Is it like that on both ends of the blade or just one end of the blade? Both blades? Where I live, the soil is very sandy. It does not take long for the sand to sandblast the tips of the blades and erode the metal away. I use Gator blades (96-319 G3) on my 42 inch Hustler Raptor. The tips move the fastest, so that is where the wear is highest. I can go through several sets of blades in a season. Good luck.Any idea what's causing this on my Troy-bilt 42" rider? These blades were only installed 2 years ago.
There is no gravel on my 1-acre.
I dont loan anything because it always comes back broken. Good tip though.Have you loaned the mower to anyone? Bingo... You may not want to do so again.
Has anyone other than you used the mower, even on your property? Bingo...They may need some training or take the keys away from them...
