I'm hoping this is because the small front roller seems to be seized solid and just flattened the longer grass in front of the blades. The roller seems to be solid steel, about 2" diameter and have a shaft that has an allen key at each end of the roller and then nuts to hold it in the frame.
Is anyone familiar with these? Are there any warnings about what not to do? I'm a bit scared of undoing something vital and ending up with small rollers (I'm too polite to mention the other type of bearing) all over the floor.
We haven't attached the ride on roller seat yet as it seems to go terribly fast for something that needs to do tight u-turns.
