Lawn Mower Ignition Key 09287000 Replaces Ariens Gravely ZT HD 44", 48", 52", 60",Apex Compact Pro 34", 44"

What It Is

This is a replacement ignition key for Ariens and Gravely zero-turn mowers, specifically designed for ZT HD models (44", 48", 52", 60") and Apex Compact Pro models (34", 44"). It’s a simple plastic-keyed switch insert—not a universal key—that starts the engine and prevents unauthorized use.

Fitment & Compatibility

Before buying, verify your mower’s model number (not just deck size) against the 09287000 OEM part number. This key fits Ariens ZT HD 44–60" and Gravely ZT HD 44–60" (including Pro and XDZ variants), plus Apex Compact Pro 34" and 44". It does NOT fit older Ariens/Gravely models with metal keys or different switch housings. Measure the key’s shaft length (approx. 1.5") and blade width (approx. 0.5")—if your current key is thicker or has a different slot shape, it won’t work. Check your owner’s manual or existing key for the 09287000 stamp.

Key Things to Know

• Quality: Aftermarket plastic key; works fine but may feel slightly less durable than OEM. Avoid excessive force when inserting.
• Installation: Zero difficulty—just insert into the ignition switch. No wiring or tools needed.
• Common gotcha: If your mower uses a different switch (e.g., pre-2015 models with metal keys), this won’t fit. Verify the switch housing shape matches the key’s profile.
• Spare vs. primary: Good as a backup or replacement for a lost key, but not a universal fit—double-check the exact model number.

Should You Buy It

Yes, if you need a direct replacement for a lost or worn 09287000 key on a compatible Ariens/Gravely ZT HD or Apex Compact Pro. At $9.50, it’s a cheap fix compared to replacing the entire ignition switch. Avoid if your mower uses a different key number or has a damaged switch.
