That is very strange. Must have something to do with the 52" deck. I have been using them since 2008 on a 60" xfactor deck. Kind of blows my mind TBH. The blades are almost identical to the oem blades. Only difference is the oem has a slight hump in the middle and less cutting surface.
This is a customers overgrown jungle. The grass was damp with dew and pretty tall here. They need to get the beds cleaned up. They treat the lawn but could care less about the beds.
This was right after we had almost 2" of rain.
Right after we bought our house. The lawn was way overgrown here. I did double cut this to clean up a little debris laying on top.
