This is a replacement hardware kit for EGO Power+ 21-inch mowers, combining the drive fan, center flange bolt, washers, support bolts, and lock nuts needed to secure the blade assembly. It’s designed for routine blade swaps or fan replacement, not for blade sharpening.
Fitment & Compatibility
Check your mower’s deck size first – this kit fits only 21-inch EGO Power+ mowers (not 20-inch or 56V models). Verify your mower’s model number against EGO’s list: LM2100, LM2101, LM2102, LM2110, LM2111, LM2130, LM2135, LM2140, LM2142, LM2150, LM2155, LM2160, LM2161, LM2162, LM2165, LM2166, LM2167. If yours isn’t listed, measure the center bolt hole diameter (should be ~5/16”) and fan height (about 2.5”). This kit replaces OEM part numbers 3403110001-K, 5640226002, 5650705002, and 5630351002. Cross-reference your old parts to confirm.
Key Things to Know
- Quality: OEM-grade steel bolts and nylon-insert lock nuts resist corrosion and vibration loosening. The drive fan is reinforced plastic – inspect for cracks before reuse.
- Installation difficulty: Easy – requires a 13mm socket and torque wrench. Tighten the center bolt to 35-40 ft-lbs; support bolts to 25-30 ft-lbs. Over-tightening can strip the blade adapter.
- Common gotcha: The drive fan is directional – the curved fins must face the deck. Install it backward and the mower will vibrate excessively or overheat.
- One-time use: Lock nuts should not be reused. If you’re just swapping blades, buy a separate nut kit unless the fan is damaged.
Should You Buy It
Buy this if you’re replacing a damaged drive fan or need all hardware for a complete blade assembly rebuild on a compatible EGO 21” mower. Skip it if you only need bolts – a generic flange bolt and lock nut set costs half as much. Good value for a full OEM-matched kit, especially if you’re already replacing the fan.
