Replacement disc for Yarbo M1 mower deck. Mulches and cuts reasonably well and self clears debris.
Printed from PETG at 100% infill.
A couple of things my 70 yo brain forgot mention ;)
The size of the stl model maybe smaller than is optimal. I printed mine at 205 mm but a 206 mm x 22mm is available.
I have added the size 206 mm
The last file is 225 mm. It has two plastic blades added to the struts. The reason it is bigger than stock is I was going to anneal it for additional strength. Unfortunately, my bigger printer is giving me trouble so I have not been able to print, anneal or test. That said feel free to give it a try but annealing it or reduce it to 215mm X,Y and 20mm Z axis. first. It SHOULD work.
