The bearings for the front wheels on the mower completely rusted away, so decided to make new ones. Unsure about the exact mower model, so please measure your old wheels before printing these.

Diameter: 90mm on center, 80mm on outside edge
Width: 46.2mm

Parts needed for each wheel:
1x wheel
2x 608ZZ bearings (Sealed skateboard bearings)
1x locking clip for a 8mm shaft (I recommend "Push-On External Retaining Ring", example partnumber 92133A109 from McMaster-Carr)
Grease (for lubrication and rustproofing)
Glue for waterproofing the caps
Optional:
1x cap for outside of wheel
2x split cap for axle side

Bearings should be a press fit, I used a bolt to pull them together in the wheel.
The stock caps can be reused, both on inside and outside of the wheel. I have not yet tested the caps attached here.
