Echo Dual Mower Blade
Genuine Echo OEM Replacement Part: 99988806001
Product Specifications:
Restore clean cutting precision, superior bagging lift, and fine mulching efficiency to your lawn mower with this genuine Echo dual mower blade set. Engineered specifically for Echo 21" self-propelled walk-behind mowers, this stacked dual-blade system uses matched cutting profiles to finely shred grass clippings and optimize under-deck airflow. Replacing both blades together maintains proper rotational engine balance, prevents crankshaft vibration, and safeguards against premature valvetrain and drive system wear.
Hardware & Maintenance Notice:
- Hardware Inspection: Inspect your blade adapter, blade mounting bolts, and friction washers for rounding, stress cracks, or thread stretching during installation. Worn hardware can cause blade slippage or dangerous rotational harmonic vibration.
- Replacement blade mounting bolts, washers, engine air filters, and spark plugs are available above in our You May Also Like... catalog tray.
- Inspect your engine oil level, spark plug condition, and drive belt tension whenever servicing cutting blades.
- Always check your machine's model number and serial number on the rear deck identification decal before ordering to ensure correct fitment.
