Which machines use this Husqvarna Craftsman 149723 muffler?

This muffler fits multiple Craftsman, Poulan and Husqvarna lawn tractors and riding mowers that originally came with the same OEM muffler design. Compatibility depends on engine model, mounting hole alignment and exhaust outlet size, so cross‑referencing part numbers and tractor model years is recommended before purchasing.

• OEM part number: Husqvarna 532149723 / Craftsman 149723
• Designed for compatible Craftsman, Poulan and Husqvarna tractors and mowers
• Matches original muffler shape, mounting bolts and exhaust port dimensions

How easy is it to install the replacement muffler?

Installation is typically straightforward for anyone comfortable working with small engine repairs. You’ll need basic hand tools, and the job often involves removing the old muffler, aligning the new unit, and tightening the mounting bolts to the manufacturer’s torque specs.

• Requires basic tools: ratchet, sockets, and possibly penetrating oil for stuck bolts
• Expect minimal disassembly of shrouds or heat shields on most models
• Follow engine cool‑down and safety guidelines before starting work

What performance and safety considerations should I expect?

The OEM muffler restores the intended exhaust routing and noise attenuation but does not change engine power. Using the correct Husqvarna/Craftsman replacement ensures heat is directed safely away from sensitive components and maintains factory emission and noise levels.

• Replaces leaking or rusted mufflers to prevent exhaust escape near wiring or fuel lines
• Lo‑tone design reduces perceived engine noise compared with damaged mufflers
• Maintains original clearance and mounting to preserve safety and fit

Will this part come with mounting hardware or gaskets?

Hardware and gaskets may not always be included; some sellers list the bare muffler only. Check the retailer listing to confirm whether bolts, studs or exhaust gaskets are supplied, and have replacements on hand if needed for a complete installation.

• Confirm included items in the product listing before purchase
• Have a compatible exhaust gasket and mounting hardware available if not supplied
• Replace corroded studs or bolts to ensure a secure, leak‑free fit

Who this is for: This OEM Husqvarna Craftsman 149723 lo‑tone muffler is intended for owners and technicians maintaining Craftsman, Poulan, or Husqvarna lawn tractors and riding mowers that require the factory replacement muffler.
