Tianchen TC-158N Blade replacement disk

thingiverse

I use a Tianchen TC-158N robot lawn mower because I'm just not motivated to mow by hand. This robot comes with two blades that are pretty subpar. You'll never get them truly sharp and they're really loud. So, I started designing some sort of blade holder. This one works best for me. It uses three blades (the standard ones used in Automower, Gardena etc.) per disk. You need two disks for this lawn mower. The disks fit perfectly on the motor shaft. You don't have to make any modifications to your mower; just unscrew the cruddy blades and screw these new ones on. BOM for one Tianchen mower: - 2 printed disks - 6 sharp blades with M4 screws (like Automower) - 6 RAMPA inserts (https://www.schraubenking.at/M4-x-8mm-Rampa-Muffe-Typ-A-Stahl-verzinkt-P003788) to mount the blades There are two versions for blade disks. One is taller and will cut your grass lower. I used the flat one and it works really well. ARDUMOWER Because I didn't like the way the mower behaved (software) and I'm a maker, I replaced the whole electronics and software with an Arduino. If you want to build your own mower (yes, it's possible) or replace the electronics of any kind of robot mower (yes, this is also possible) because it's damaged or doesn't work well, visit www.ardumower.de Here you'll find everything you need like software, examples, tutorials, forum, plans etc.
