1737816 Lawn Mower Blades for 42" Deck, Compatible with Snapper Simplicity Murray Riding Mowers, Replaces 1737816BMYP 1737816BZ 1737816SM 1737816YP, 2 Pack

What It Is

This is a 2-pack of replacement mower blades for 42-inch cutting decks, designed for Snapper, Simplicity, and Murray riding mowers. It’s a direct aftermarket replacement for OEM part numbers 1737816BMYP, 1737816BZ, 1737816SM, and 1737816YP.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Only fits 42" decks. Measure your deck width (blade tip to tip) to confirm.
• Model/brand: Works with Snapper (e.g., 2812, 3314 series), Simplicity (e.g., Broadmoor, Regent), and Murray (e.g., select 42" riders). Check your mower’s model number (often under seat or on deck).
• OEM cross-reference: Replaces part numbers 1737816BMYP, 1737816BZ, 1737816SM, 1737816YP. If your current blade has any of these stamped on it, it’s a match.
• Measurements: Center hole is typically 1" diameter, blade length ~21" (tip to tip). Measure your old blade before ordering.

Key Things to Know

• Quality: Aftermarket blades, not OEM. Expect comparable steel thickness and sharpness, but may not last as long as genuine Snapper blades in heavy use.
• Installation: Straightforward – remove center bolt, swap blades, torque to 30-40 ft-lbs. Use a blade removal tool if the bolt is seized.
• Balance: Not pre-balanced. Check balance on a blade balancer after install to avoid vibration and deck damage.
• Gotcha: These are standard lift blades – not mulching or high-lift. If you need bagging performance, consider a high-lift alternative.

Should You Buy It

Buy this if you have a Snapper, Simplicity, or Murray 42" rider and want a budget-friendly, bolt-on replacement for standard cutting. It’s a solid value at $31 for two blades, but skip it if you need OEM durability for commercial use or require mulching/high-lift design.
