Replacement Lawn Mower Deck Lift Handle Release Button Kit 510207301 510030702 Fits Husqvarna Poulan Jonsered Lawn Mower

What It Is

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

Fitment & Compatibility

• OEM part numbers: 510207301 and 510030702 – cross-reference these with your mower’s manual.
• Fits models: Husqvarna YTH, GTH, LTH series; Poulan Pro/Poulan; Jonsered. Does not fit older Craftsman or MTD decks.
• Check your handle: This kit replaces the button and spring assembly on the lift lever. Measure the handle diameter (typically 1/2” or 5/8”) to ensure the button fits.
• Deck size: Compatible with 42”, 46”, 48”, and 54” decks on these brands.

Key Things to Know

• Quality: OEM-spec plastic and spring; holds up well under normal use. Avoid cheap generic knockoffs that crack.
• Installation difficulty: Easy (10–15 minutes). You’ll need a flathead screwdriver to pry out the old button and a pair of pliers to snap in the new spring.
• Common gotcha: The button can be stubborn to remove if the handle is rusted. Spray a little WD-40 on the old button before prying.
• Not a universal part: Will not fit zero-turn mowers or older Husqvarna models with a different lift mechanism.

Should You Buy It

If your deck lift button is broken, sticking, or missing, this kit is a direct, affordable fix for Husqvarna, Poulan, or Jonsered tractors. It’s a cheap repair that avoids replacing the entire lift handle assembly.
