D693 (2) HD Blades Fits Hustler 42" Raptor Replaces 793794 794685

What It Is

This is a set of two high-lift mulching blades designed for 42-inch Hustler Raptor zero-turn mowers. They replace OEM part numbers 793794 and 794685, intended for thick grass, bagging, or light mulching where extra airflow is needed.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: These blades fit only 42-inch Hustler Raptor decks. Measure your deck width to be sure.
• Model range: Compatible with most Hustler Raptor models (SD, SR, etc.) from 2012 onward, but double-check your mower’s serial number against Hustler’s parts list for 793794 or 794685.
• Measurements: Blade length must be 20.5 inches, center hole diameter 1 inch, and thickness 0.204 inches. Aftermarket blades can vary slightly, so measure your old blade before ordering.
• Mounting pattern: These use two bolt holes on a 3.5-inch center. Ensure your spindle matches.

Key Things to Know

• Quality vs. OEM: D693 blades are thicker steel than some OEM blades, but the cutting edge may dull faster if you hit rocks or roots often. Expect 20–30 hours of normal use before sharpening.
• Installation: Easy bolt-on swap. Use a torque wrench to 55–65 ft-lbs. Never reuse old lock washers.
• Common gotcha: High-lift blades increase suction but also engine load. If your mower bogs in tall grass, switch to standard lift blades instead.
• Balance check: Aftermarket blades sometimes need light balancing. Use a blade balancer to avoid vibration that can damage spindles.

Should You Buy It

Buy these if you have a 42-inch Hustler Raptor with a standard spindle, you want a budget alternative to OEM blades, and you’re comfortable with a quick balance check. Skip them if you need extreme durability for rocky yards or if your deck uses a different bolt pattern.
