Maxpower 336319 Deck Drive Belt for 46" Cut Poulan/Husqvarna/Craftsman, 405143, 532405143, 58445310 and Many Others

What It Is

The Maxpower 336319 is an aftermarket deck drive belt designed for 46-inch cutting decks on select Poulan, Husqvarna, and Craftsman lawn tractors. It transfers power from the engine pulley to the spindle blades, making it essential for mowing.

Fitment & Compatibility

Before buying, confirm three things: your deck measures exactly 46 inches (blade tip to blade tip), your mower brand matches Poulan, Husqvarna, or Craftsman models from the late 1990s through 2010s, and your original belt part number is one of these: 405143, 532405143, 58445310, or 336319. This belt is 94.7 inches long, 0.5 inches wide, and has a K-section (standard V-belt profile). It replaces OEM belts from those brands. Measure your old belt’s length and width (lay it flat, measure end to end) to double-check—aftermarket belts can vary slightly. Avoid using it on 42-inch or 54-inch decks; it won’t fit.

Key Things to Know

• Quality: Users report it lasts 1-2 seasons under normal use, similar to OEM belts. It’s Kevlar-reinforced for durability, but not as tough as premium aftermarket options like Stens.
• Installation: Moderate difficulty—expect 30-60 minutes. You’ll need to remove the deck, loosen the tensioner pulley, and route the belt per your mower’s diagram. A belt tension gauge helps avoid slipping.
• Common gotcha: The belt may be slightly stiff when new—run the mower for 5-10 minutes at low speed to seat it. If it chirps, check alignment of the pulleys (bent spindles cause premature wear).
• Warranty: Maxpower offers a 1-year limited warranty. Keep your receipt; returns are straightforward if it breaks early.

Should You Buy It

Buy this belt if you own a 46-inch Poulan, Husqvarna, or Craftsman tractor and want a reliable, budget-friendly replacement that matches OEM specs. It’s not the longest-lasting option, but for $22.70 and a 4.5-star average from 1,450 reviews, it’s a solid choice for most homeowners. Skip it if you need a heavy-duty belt for commercial use or have a different deck size.
