Rotary 28 1098 Rear Engine Rider Lawnmower Blade Snapper 1-9515 7019515

What It Is

This is a direct-replacement rotary blade for Snapper rear-engine riders (RER) and select Murray models. It’s designed for cutting grass on residential lawns, not for mulching or bagging—standard high-lift blade for side discharge.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Fits 28-inch and 30-inch cutting decks only. Measure your deck width (blade tip to tip) to be sure.
• Model numbers: Direct OEM replacement for Snapper part numbers 1-9515 and 7019515. Also cross-references to Rotary 28-1098. Fits Snapper RER models from the 1990s through early 2000s (e.g., 280, 300 series). Some Murray rear-engine riders with the same deck size also accept it.
• Measurements: Blade length is 21 inches, center hole diameter is 5/8 inch, and it has a 1/4-inch offset. Compare these to your old blade—if the hole or offset differs, it won’t mount correctly.
• OEM vs aftermarket: This is an aftermarket blade from Rotary, a reputable brand. It’s functionally identical to the Snapper OEM blade at a lower price. No adapter or modification needed.

Practical check: Remove your current blade and measure length, center hole, and offset (lay it flat on a table). If all match, this blade will fit.

Key Things to Know

• Quality: Made from heat-treated, tempered steel. Holds an edge well for residential use, but won’t outlast OEM Snapper blades on heavy-duty or frequent cutting. Expect 1–2 seasons with normal use.
• Installation: Easy—just one bolt per blade. Use a torque wrench to 50–60 ft-lbs. The blade is marked with “this side up” or has a stamped arrow; ensure it faces the deck (sharp edge leads when spinning). No special tools beyond a socket wrench.
• Common gotcha: The blade is for side-discharge decks only. If your Snapper has a mulching kit or bagger, this blade won’t work well—you need a mulching or low-lift blade instead. Also, check that your deck spindle isn’t bent before installing (spin the old blade by hand to see if it wobbles).
• Balance: Out of the box, these are typically balanced. But after sharpening, always rebalance with a blade balancer to avoid vibration that can damage the spindle.

Should You Buy It

If you own a Snapper rear-engine rider with a 28- or 30-inch deck and need a reliable, affordable replacement for standard side-discharge mowing, this blade is a solid choice. It’s not for heavy commercial use or mulching setups, but for home lawn care, it delivers good cut quality and value. Just confirm your deck size and blade measurements first.
