HD Switch - OEM Upgrade - w/Rigid Arm and Extended Base for Ease of Use - Mower Deck Leveling Gauge Leveler Gage Replaces John Deere AM130907 MTD 490-900-0041 Cub Cadet 490-900-0041 Stens 750-442

What It Is

This is a deck leveling gauge that replaces OEM part AM130907 (John Deere), 490-900-0041 (MTD/Cub Cadet), and Stens 750-442. It measures blade height and deck pitch, with a rigid arm and extended base for easier one-handed use on zero-turn and riding mowers.

Fitment & Compatibility

• Direct fit for: John Deere (AM130907), MTD, Cub Cadet, and other brands using the same OEM number.
• Check before buying: Measure your deck’s blade-to-ground clearance range (typically 1–5 inches). This gauge works for most standard decks but not all commercial zero-turns with unusual deck profiles.
• Cross-reference: Verify your model number against AM130907 or 490-900-0041 in your owner’s manual or online parts lookup.
• Physical check: The extended base is about 6 inches long—ensure it fits under your deck without hitting belts or spindles.

Key Things to Know

• Quality: Solid plastic build; holds up to regular use but avoid dropping on concrete. The rigid arm stays straight, unlike cheaper flexible gauges.
• Installation: No tools needed—just slide under the deck and read the scale. Takes 30 seconds per side.
• Common gotcha: The scale is in 1/4-inch increments, not 1/8-inch. If you need finer adjustments, this won’t be precise enough.
• Fitment note: Works on most residential riding mowers, but some older Craftsman or Husqvarna decks may require a different gauge due to non-standard blade heights.

Should You Buy It

If you own a John Deere, Cub Cadet, or MTD riding mower and want a quick, repeatable way to level your deck without guesswork, this is a reliable, low-cost upgrade. It’s not for commercial shops needing high precision, but for homeowners doing seasonal maintenance, it’s a solid choice.
