What It Is

This is a replacement spindle drive pulley for the mower deck on Husqvarna lawn tractors. It transfers belt power from the engine to rotate the blade spindle, and this 2-pack is designed for 42" and 46" cutting decks.

Fitment & Compatibility

Before buying, confirm your deck size and model. This pulley fits Husqvarna 42" and 46" deck models including 2146XLS, 2246LS, LT152, LT1942, LTH152, LTH2042, and YTH20K46. It replaces OEM part numbers 21546446, 197473, 532195945, and 532197473. Measure the pulley’s outer diameter (3.5") and center hole diameter (0.625"). If your existing pulley matches these dimensions, it will fit. Double-check your mower’s model number on the frame or deck—not just the series name—to avoid mismatch. This is an aftermarket part, not OEM Husqvarna, but meets OEM specs.

Key Things to Know

• Quality: Made from stamped steel with a zinc finish. It’s durable for residential use but may wear faster than OEM under heavy commercial conditions.
• Installation: Straightforward—remove the old pulley, clean the spindle shaft, and slide the new one on. Use a torque wrench to tighten the center bolt to 30-40 ft-lbs (check your deck manual). No special tools needed.
• Common gotchas: The pulley’s keyway must align with the spindle shaft’s flat spot. If your shaft is worn or bent, replace the spindle assembly too. Also, verify belt routing before reassembly—wrong routing causes slipping.
• Pack includes: Two pulleys, so you can replace both spindles at once or keep one as a spare.

Should You Buy It

If you own a Husqvarna 42" or 46" deck tractor and need a budget-friendly replacement for a worn or missing spindle pulley, this 2-pack is a solid value. It’s best for DIY homeowners doing routine deck maintenance—not for heavy commercial use. Just confirm your deck model and shaft dimensions before ordering.
