Replacement 84005711 Spindle Assembly for Snapper SZ2042 Model 967947601 967947701

What It Is

The 84005711 spindle assembly is the rotating hub that drives the mower blade on a zero-turn mower. It’s designed specifically for Snapper’s 20-horsepower, 42-inch deck models (SZ2042 series) used by homeowners and light commercial operators.

Fitment & Compatibility

Check these before buying:

• Model numbers – Confirmed fit for Snapper SZ2042 models 967947601 and 967947701. Verify your unit’s model number on the frame tag (not the engine).
• Deck size – Only for 42-inch fabricated decks. Will not fit 48-inch or 52-inch decks.
• Spindle bolt pattern – 3-bolt flange, 3-inch center-to-center. Measure your old spindle’s bolt spacing if unsure.
• OEM vs aftermarket – This is an OEM Snapper part (original manufacturer), not a generic replacement. Expect exact fit without modification.
• Blade compatibility – Uses a 5/8-inch hex shaft. Standard Snapper blades (OEM or aftermarket) with the same center hole work.

Key Things to Know

• Quality – OEM construction with sealed bearings. Generally lasts 2–4 seasons with normal residential use. Replace in pairs if the other spindle shows wear.
• Installation difficulty – Moderate. Requires removing the deck, unbolting the old spindle (3 bolts top, 3 bolts bottom), and transferring the pulley and blade. Basic socket set and a torque wrench (30–40 ft-lbs on flange bolts) recommended.
• Common gotcha – The pulley nut often seizes. Use penetrating oil and an impact wrench if possible. Replace the pulley if damaged during removal.
• Tip – Check for deck cracks around the spindle mount before installing. A bent deck will quickly ruin a new spindle.

Should You Buy It

If you own a Snapper SZ2042 (model 967947601 or 967947701) with a 42-inch deck and need a direct, bolt-on replacement, this is the correct part. It’s priced fairly for OEM quality and avoids the fitment headaches of generic spindles. Best for DIY repairs on residential mowers—commercial users may prefer a heavier-duty aftermarket option.
