FourShow Replacement Blades for Mammotion LUBA & Yuka, 36-Pack Review

Our Verdict

If you own a LUBA or Yuka this is the volume blade option, and the reason to keep a stock is UF/IFAS's instruction that blades be replaced every six to eight weeks during the growing season to maintain cut quality. On a machine that cuts every day, a blade past its life tears grass continuously rather than once a week — which quietly cancels the clean-cut advantage that makes robotic mowing agronomically worthwhile in the first place. Thirty-six blades with the plastic washers included covers roughly two seasons. Two honest marks against it. At a 4.3 Amazon average this is the weakest-rated blade set here, which for a commodity part is worth noting rather than shrugging off. And Mammotion's own blades are the fit-certainty alternative on a $2,200–$3,300 machine. We rate it 4.0 on that basis, not because it fails — it is the sensible bulk choice, just not the flawless one.
