Husqvarna OEM 592855201 Drive Belt K46 YTH18542 YTH22V46 YTH24V48 TS142 TS146

What It Is

The Husqvarna OEM 592855201 is a K46 drive belt that transfers power from the engine to the transmission (hydrostatic or manual) on select Husqvarna and Craftsman lawn tractors. It’s a direct replacement for the original belt on 42", 46", and 48" deck models, designed for residential mowing.

Fitment & Compatibility

Before buying, confirm your mower’s model number (e.g., YTH18542, YTH22V46, YTH24V48, TS142, TS146) and deck size. This belt specifically fits Husqvarna K46 transmission-equipped tractors, not all Husqvarna models. Measure the old belt’s length (approx. 92.5" outer circumference) and width (1/2"). Cross-check with OEM part numbers: also fits 532 59 28-55 (Craftsman). Avoid if your mower uses a K66 or T46 transmission—belt dimensions differ. Check your owner’s manual or the existing belt’s part number for absolute match.

Key Things to Know

• Quality: OEM Husqvarna belt is kevlar-reinforced, more durable than most aftermarket belts—expect 2-3 seasons with normal use. Aftermarket belts often wear faster or slip.
• Installation: Moderate difficulty (30-60 minutes). You’ll need to remove the mower deck and belt covers, then route the belt around pulleys and the transmission. A diagram is helpful—take a photo before removal.
• Gotchas: The belt is tensioned by a spring-loaded idler pulley. If the belt is too tight or loose, check pulley alignment and tensioner condition. Replacing the belt without checking the idler pulley bearings can cause premature wear.
• Not for zero-turn mowers: This is for lawn tractors only—no ZT models.

Should You Buy It

If you own a compatible Husqvarna or Craftsman lawn tractor (YTH/TS series) and want a reliable, long-lasting drive belt that matches factory specs, this OEM belt is a solid choice. It’s priced fairly for the durability, but if you’re on a tight budget, a quality aftermarket belt (e.g., Stens) may work—just expect shorter life. For most homeowners, this is the “buy it once” option.
