MowerPartsGroup (2) Mulching Style Toothed Blades Fits Hustler 42" FasTrak Raptor Dash 794230

What It Is

This is a set of two mulching-style toothed blades designed for Hustler 42-inch Fastrak, Raptor, and Dash zero-turn mowers. They are aftermarket replacements for OEM part #794230, intended for mulching grass clippings into finer particles rather than side-discharging or bagging.

Fitment & Compatibility

Before buying, verify your mower has a 42-inch cutting deck and accepts two blades (not three). This set fits Hustler Fastrak, Raptor, and Dash models that use OEM blade 794230. Measure your current blade length (should be ~21 inches) and center hole diameter (likely 1 inch). Check that the blade thickness matches your spindle clearance. If your mower uses a different OEM blade number or has a 48/54/60-inch deck, these won’t fit. Also confirm your deck is designed for mulching—some Hustler models require a mulching kit or baffle to work properly.

Key Things to Know

• Quality: Aftermarket blades are typically stamped steel; they’re durable but may not hold an edge as long as OEM or high-carbon blades. Expect to sharpen or replace more frequently.
• Installation: Easy bolt-on job if you have a socket set and jack stands (or tilt the mower safely). Use a torque wrench to tighten to manufacturer spec (~70-90 ft-lbs). Do not overtighten.
• Common Gotchas: The toothed design can clog in wet, thick grass—mulch only when grass is dry. Also, these blades may slightly reduce lift compared to standard blades, so avoid mowing tall grass in one pass (cut no more than 1/3 of the grass height).
• Balance: New blades are often balanced, but check with a blade balancer before installing. An unbalanced blade can vibrate and damage the spindle.

Should You Buy It

Buy these if you own a Hustler 42-inch Fastrak, Raptor, or Dash and want a budget-friendly mulching blade set that gets the job done for occasional use. They’re a good value for homeowners who mow weekly and don’t need premium edge retention. Skip them if you mow heavy commercial lawns daily or require OEM-grade durability—invest in Hustler-branded blades instead.
