Stens New Spindle Assembly 285-110 Compatible with MTD 600 and 805 Series 32" and 42" Deck G and 38" Deck F 717-0906, 717-0906A, 753-05319, 917-0906A

What It Is

The Stens Spindle Assembly 285-110 is a replacement spindle for MTD 600 and 805 Series lawn tractors, designed for 32" and 42" decks (G series) and 38" decks (F series). It houses the pulley and blade shaft that drive the cutting blade, critical for smooth, vibration-free mowing.

Fitment & Compatibility

Before buying, verify these specifics:

• Deck size & series: Fits MTD 600 Series (32" and 42" G decks) and 805 Series (38" F deck). Not for other deck sizes or series.
• OEM cross-references: Replaces MTD 717-0906, 717-0906A, 753-05319, and 917-0906A. Confirm your OEM part number matches one of these.
• Measurements: Check spindle shaft diameter (typically 5/8" or 3/4") and overall height. Stens 285-110 uses a 5/8" shaft; measure your old spindle to confirm.
• Mounting pattern: Verify bolt hole spacing and pattern matches your deck—measure center-to-center distance on your current spindle.
• Brand compatibility: Stens is aftermarket, not OEM. It’s a direct fit for listed MTD models but double-check deck mounting holes and pulley alignment.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand, generally comparable to OEM. Expect durable bearings and housing, but not identical to MTD’s original.
• Installation difficulty: Moderate. Requires removing the old spindle (may need a puller), installing the new one with proper torque (typically 30-40 ft-lbs), and ensuring the blade is balanced.
• Common gotchas:
  • The pulley may not be included—check if your old pulley is reusable or buy separately.
  • Grease fittings may be present; grease before first use.
  • Blade bolt thread direction: some MTD spindles use reverse threads (left-hand)—verify yours.
• Noise/vibration: If the spindle is loose or bearings are dry, expect wobble. Tighten all bolts and grease immediately.

Should You Buy It

If you have an MTD 600 or 805 Series tractor with the specified deck and your OEM spindle is worn (noisy, wobbling, or seized), this Stens spindle is a solid, cost-effective replacement. It’s reliable, well-reviewed, and cheaper than OEM, but verify fitment with your exact deck model and measurements before ordering.
