Rotary # 2006 High Lift Lawn Mower Blade For 21" Cut For Snapper # 7019645 7017002

What It Is

The Rotary #2006 is a high-lift lawn mower blade designed for 21-inch cut decks. It is intended to replace OEM Snapper parts #7019645 and #7017002, offering increased airflow for better grass clipping discharge, especially in thick or wet grass.

Fitment & Compatibility

Before buying, confirm your mower deck has a 21-inch cutting width. This blade fits most Snapper 21-inch walk-behind mowers, including many models with the 7019645 or 7017002 OEM blade. Measure your existing blade: it should be approximately 21 inches long, with a 1-inch center hole and a 5-point star center pattern (common on Snapper decks). Check the blade thickness (typically 0.125 inches) and ensure the deck’s spindle matches. Not compatible with universal or non-Snapper decks without verifying the star pattern and hole size.

Key Things to Buy

• Quality: Made of heat-treated steel for durability; high-lift design improves bagging and side discharge but may increase engine load.
• Installation: Straightforward—remove the old blade, clean the spindle, and torque the bolt to manufacturer specs (usually 30-50 ft-lbs). Use a blade removal tool for safety.
• Gotchas: High-lift blades can cause stalling in underpowered mowers or when cutting very tall grass. Ensure your blade bolt is not worn or stripped before reinstalling.
• Maintenance: Sharpen or replace when nicked or dull; balance the blade after sharpening to avoid vibration.

Should You Buy It

Buy this blade if you own a Snapper 21-inch walk-behind mower with the 7019645 or 7017002 OEM blade and need improved grass lift for bagging or wet conditions. It’s a high-quality, direct-fit upgrade that works well for homeowners and pros alike, but avoid it if your mower has a standard universal blade pattern or you prefer a low-lift blade for dusty, dry conditions.
