FourShow 【Cut More Efficiently】 Blade Discs + 6 Replacement Blades Compatible with Husqvarna Automower for G3-P15, 305,310,315,315x,405,410,415x,435,535 AWD Series Separator Robotic Lawn Mower

What It Is

This is a set of replacement blade discs and six spare blades designed for Husqvarna Automower robotic mowers. It’s intended to restore cutting performance when the original discs are worn, bent, or have broken blade retention.

Fitment & Compatibility

• Exact models: G3-P15, 305, 310, 315, 315x, 405, 410, 415x, 435, 535 AWD – plus any model using the same three-blade pattern on a 180mm disc.
• OEM cross-reference: Replaces Husqvarna part numbers 580 77 67‑01 (disc) and 580 78 59‑01 (blades). Not compatible with older models (e.g., 220, 260) or G2‑series discs.
• What to measure: Disc diameter must be 180mm (7.1″). Blade length is 100mm (3.9″). Count your original disc slots – this set has three slots, each holding one blade.
• Check before buying: Verify your current disc has a center hole that matches the drive pin pattern (4‑pin, 90° offset). If your mower uses a different drive system (like a hex shaft), this won’t fit.

Key Things to Know

• Installation is tool-free: Blades snap into the disc slots; no screws or bolts. Push old blades out from the back, slide new ones in.
• Blade orientation matters: The cutting edge must face the direction of disc rotation (clockwise when viewed from below). Installing backwards will reduce cut quality and wear blades faster.
• Quality is decent for the price: Blades are stamped steel, not hardened like OEM. They’ll dull faster but are cheap to replace. The discs are injection-molded plastic – check for flash or rough edges before installing.
• Disc wear is common: If your old disc has cracked slots or a wobbly center hub, replace it. Running a warped disc can damage the mower’s cutting motor.

Should You Buy It

Buy this if you have a compatible Husqvarna Automower and want a budget-friendly way to refresh cutting performance. It’s ideal for owners who replace blades frequently and don’t mind slightly faster wear vs. OEM. Skip it if you need hardened, long-life blades for heavy-duty use or if your mower uses a different disc size or drive pattern.
