Robotic lawn mower cutting disc by mdjurfeldt

Last crawled date: 3 years, 1 month ago

This is a robotic lawn mower cutting disc designed for the Liam6 robotic lawn mower, but could be used for any mower with an M8 bolt for the axis.
The ideas behind the design are to:
distribute forces a bit to allow for printing with a lower strength material, like PLA,
allow for the knives (standard robotic lawn mower knives with their M4 screws) to freely rotate around their screws, thereby reducing damage due to mechanical chock,
lower the cutting disc to a level corresponding to a max grass height of approximately 4 cm for the Liam6 design, and,
protect the spinning knives with a cover as in some commercial mowers.
FreeCAD files are included.
Knives, with their screws for free rotation, can, e.g., be found on ebay.
