2 Pack 197473 Pulley Replaces 532195945 Mandrel Pulley, Husqvarna 532197473 Pulley, 195945, 532199478, 709731, 705115, 21546446, Oregon 78-062 for Husqvarna YTH22V46, YS4500 Decks

What It Is

This is a 2-pack of replacement mandrel pulleys designed for Husqvarna YTH22V46 and YS4500 series mower decks. It drives the blade belt to spin the cutting blades; the 197473 part number replaces OEM 532195945, 532197473, 195945, 532199478, 709731, 705115, 21546446, and Oregon 78-062.

Fitment & Compatibility

Before buying, check your mower’s deck size (must be 46-inch) and confirm your model is YTH22V46 or YS4500. Also verify your pulley diameter (3.5 inches) and shaft size (5/8-inch bore). This aftermarket pulley matches OEM specs but is not a genuine Husqvarna part—it’s a direct replacement for the original 197473/195945. Do not use on 42-inch or 54-inch decks; pulley size will be wrong.

Key Things to Know

• Quality: All-metal construction, but some users report slightly thinner metal than OEM; fine for residential use but may wear faster under heavy commercial loads.
• Installation: Easy to swap if you have basic tools (socket wrench, pry bar). Requires removing the deck belt, then unbolting the old pulley (usually a 15/16-inch nut). Torque to 30-40 ft-lb.
• Common gotcha: The pulley may come with a sharp edge on the inner race—file it smooth before installing to avoid belt damage.
• Pack contents: You get two pulleys (good for dual-spindle decks or as a spare), but no hardware (reuse your original bolt and washer).

Should You Buy It

Buy this if you have a Husqvarna YTH22V46 or YS4500 with a worn or noisy mandrel pulley and want a budget-friendly 2-pack for under $21. It’s a solid, easy DIY replacement for residential mowing, but if you mow commercially or need OEM-grade durability, stick with the genuine Husqvarna 532197473.
