EPR Tune Up Maintenance Kit Blades Oil Filters Replacement for 42 Inch Hustler Raptor & Limited

What It Is

The EPR Tune Up Maintenance Kit bundles four high-lift mower blades, an oil filter, and an air filter for a complete service refresh on 42-inch Hustler Raptor and Limited series zero-turn mowers. It’s designed for homeowners and light commercial users doing an annual tune-up.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch cutting deck. This kit fits Hustler Raptor SD, Raptor SR, Raptor Flip-Up, Raptor Limited, and Raptor SX models with a 42-inch deck. The blades measure 18.5 inches long, 2.5 inches wide, 0.25 inches thick, with a 1-inch center hole and a 3/8-inch offset. The oil filter cross-references to Hustler OEM part 171234 and commonly fits Kohler and Kawasaki engines used on these models. Check your owner’s manual for exact engine filter specs—some Raptor models use a different filter if equipped with a Briggs & Stratton engine. The air filter is a foam pre-filter style, not a paper cartridge, so verify your mower’s air box accepts foam.

Key Things to Know

• Blade quality: High-lift blades improve bagging and mulching but increase engine load; they’re fine for most 42-inch decks, but avoid using on very wet grass to prevent clogging.
• Installation difficulty: Medium. You’ll need a socket wrench and torque wrench (blade bolt torque: 70-90 ft-lbs). The oil filter is hand-tighten only.
• Common gotcha: The oil filter may not fit all Raptor models with a Briggs engine—double-check your engine make before buying. The blades are sold as a set of four, but some Raptor decks use only three blades (check your deck’s spindle count).
• Maintenance interval: Replace blades every 25 hours of use or when nicked/dull; change oil filter annually or every 50 hours.

Should You Buy It

If you own a 42-inch Hustler Raptor or Limited with a Kohler or Kawasaki engine and want a one-stop tune-up kit with decent blades, this is a good value at $75.99. It’s not for commercial use or decks larger than 42 inches—those need heavier-duty blades. For a quick annual refresh without sourcing parts separately, it’s a solid choice.
