[Upgrade] Knife Discs + 7 Pieces Blades Compatible with Mammotion YUKA Mini Series 500 700, Lawn Mower Robot Blade Disc, Lawn Robot Rotary Disc

What It Is

This is a replacement/upgrade set of rotary disc blades for Mammotion YUKA Mini Series robotic lawn mowers (models 500 and 700). The kit includes 7 blade discs and 7 matching blades, designed to improve cutting performance or replace worn factory parts.

Fitment & Compatibility

• Exact models: Mammotion YUKA Mini 500 and YUKA Mini 700 only. Not compatible with YUKA 1000, 1500, or other Mammotion series.
• OEM vs aftermarket: This is a third-party upgrade—not Mammotion OEM. Check your mower’s disc mounting pattern (center hole diameter and pin layout) against the included discs. Measure your original disc’s outer diameter; this set should match the factory 10 cm (approx. 4 inch) disc.
• Deck size: Fits the standard YUKA Mini deck (no deck modification needed).
• Blade count: 7 blades per set—exactly what the YUKA Mini uses per full disc replacement. If your mower has 6 blades per disc, this set won’t work.

Key Things to Know

• Quality variance: At 4.1 stars, some users report the discs are slightly thinner or the blade edges dull faster than OEM. Inspect for burrs before installation.
• Installation: Simple—remove old disc, swap blades (use included screws if provided), hand-tighten. No special tools, but check that blades spin freely after tightening.
• Common gotcha: Blades may be slightly longer or thicker than factory. If they rub against the mower body or deck shroud, you’ll need to trim or file them down.
• Durability: Not recommended for heavy-duty use on thick, wet grass or rocky terrain. Expect to replace blades more often than OEM in abrasive conditions.

Should You Buy It

Buy this set if you need a budget-friendly replacement for worn YUKA Mini 500/700 discs and blades and are willing to do a quick fitment check and occasional blade swaps. Skip it if you require exact OEM durability, run your mower daily on rough terrain, or want guaranteed no-mod installation—stick with Mammotion factory parts.
