Replacement 510207301 Deck Lift Handle Button Compatible with Husqvarna Jonsered Poulan Lawn Tractor

What It Is

This is the release button for the deck lift handle assembly on select Husqvarna, Jonsered, and Poulan lawn tractors. It allows you to disengage the handle to raise or lower the cutting deck.

Fitment & Compatibility

Before buying, confirm your tractor’s model number (found on a sticker under the seat or frame). This part (OEM 510207301) replaces the original button on Husqvarna, Jonsered, and Poulan models with 42-inch, 46-inch, or 54-inch decks that use a spring-loaded lift handle. It is not universal—check that your handle assembly uses a push-button release rather than a pull-cable or lever. Measure the button shaft diameter (typically 0.25 inches) and overall length (about 1.5 inches) to match your existing button. Aftermarket versions may vary slightly in plastic quality or spring tension.

Key Things to Know

• Quality: OEM-grade plastic; aftermarket versions may feel less robust but still function. Check for sharp edges that could wear the handle slot.
• Installation: Easy—remove the old button (often held by a retaining clip or screw), slide the new one in, and re-secure. No special tools needed. Takes 5–10 minutes.
• Common gotcha: The button’s spring can pop out during installation. Work over a towel or in a clear area to avoid losing it.
• Fitment nuance: Some Husqvarna models (e.g., YTH series) use a slightly different button shape. Double-check your model against the OEM parts diagram.

Should You Buy It

If your deck lift button is broken, missing, or sticking, this is a cheap, direct replacement that restores smooth deck height adjustment. It’s ideal for DIY owners of Husqvarna, Jonsered, or Poulan tractors from the mid-2000s onward who want a quick fix without replacing the entire lift handle assembly.
