I also noticed that the blades were loose on the blade holder. I have also removed the blades to check out the bolts, holder and blades for wear. They all look good, but I would like to know if the blades should be tight onto the holder, or slightly loose on the holder to allow them to spin if I hit anything solid?
Hello Beantin
Yep, if you have pathways, these are great machines.

The blades should be able to spin on their holder for shock resistance.
But they should not be loose.

Hope this helps.
