Important Notes

• Verify part number 596210401 before ordering
• Confirm compatibility with your specific Husqvarna 21-inch push mower model and deck configuration
• Do not assume compatibility with every 21" mower based solely on deck size
• Compare the original door’s dimensions, shape, contour, hinge or pivot locations, mounting points, retaining features, and overall configuration
• Verify that your mower requires a rear-position mulch door rather than a side-discharge or differently configured door
• Inspect associated hinges, pivot pins, springs, brackets, clips, retainers, discharge components, and mounting points for wear or damage
• Verify whether any springs, hinge pins, brackets, clips, retainers, or mounting hardware are included or must be purchased separately
• Make sure the door moves and seats correctly without binding or interfering with surrounding mower components
• Shut off the mower and ensure the blade has completely stopped before inspecting or servicing the deck area
• Do not operate the mower with required doors, guards, shields, or discharge components removed or improperly secured
• After installation, verify proper door movement, closure, retention, alignment, and deck clearance before returning the mower to normal operation
