Stens Drive Plate, Snapper 7073528YP, ea, 1 (240-671)

What It Is

The Stens Drive Plate (240-671) is a replacement part for Snapper and other lawn mowers, designed to transfer power from the engine to the blade spindle. It’s a critical component in the cutting deck’s drive system, used primarily on walk-behind mowers and riding mowers with belt-driven decks.

Fitment & Compatibility

Before buying, check your mower’s model number and deck size. This plate directly replaces Snapper OEM part 7073528YP and fits many Snapper models (e.g., 21-inch walk-behinds, some rear-engine riders) and compatible brands like Murray or MTD. Verify the bolt pattern—this plate uses a 4-hole pattern with a 2-inch center hole. Measure your existing plate’s outer diameter (typically 5 inches) and thickness (about 0.25 inches). Not for zero-turn mowers or decks with different spindle designs. Cross-reference with your owner’s manual or Stens fitment guide.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand—this plate is built to OEM specs, often with hardened steel for durability. Expect similar lifespan to the original.
• Installation Difficulty: Moderate. Requires removing the blade, spindle assembly, and belt. Have a socket set, torque wrench (blade bolts: 30-50 ft-lbs), and penetrating oil for rusted fasteners.
• Common Gotchas: Check for warped or worn spindle pulleys before installing—replacing only the plate may not fix vibration if the pulley is damaged. Ensure the drive belt is aligned correctly; misalignment can cause premature wear.
• Warranty: Stens offers a 1-year warranty against defects, but not for installation errors.

Should You Buy It

Buy this if your Snapper or compatible mower has a worn or broken drive plate causing blade disengagement, poor cutting, or vibration. It’s a cost-effective fix for DIYers comfortable with deck disassembly—skip if you’re not confident with spindle work or if the entire spindle assembly is damaged (replace that instead).
