8TEN Belt PTO Clutch Kit for AYP Husqvarna YTH1842 YTH2042 YTH18542 LTH1542 YTH1542XP YTH2242A 180505 174883 532174883

What It Is

This is a complete PTO (power take-off) clutch kit that engages and disengages the mower blades on select AYP/Husqvarna lawn tractors. It replaces the OEM part numbers 180505 and 174883 (532174883) and is designed for 42-inch and 46-inch deck models.

Fitment & Compatibility

Before purchasing, verify your mower’s model number (not just the deck size) against the list: YTH1842, YTH2042, YTH18542, LTH1542, YTH1542XP, YTH2242A. Also check your original clutch’s part number—this kit fits only where 180505 or 174883 was used. Measure the pulley diameter (typically 3.5 inches) and the shaft size (1 inch). This is an aftermarket replacement, not OEM, so minor fit differences may occur on older or modified decks. Confirm your mower has a 12V electrical PTO system (most do).

Key Things to Know

• Installation difficulty: Moderate. Requires basic mechanical skills, a socket set, and a multimeter to test electrical continuity. Plan 1–2 hours.
• Quality concerns: Some users report shorter lifespan than OEM (2–3 seasons vs 4–5). Check for warped pulleys or weak bearings upon arrival.
• Common gotcha: The clutch must be gapped to 0.010–0.015 inches before installation—use a feeler gauge. Skipping this step causes premature wear or failure.
• Wiring note: The kit includes a pigtail connector; if your mower’s harness is different, you may need to splice or adapt.

Should You Buy It

This is a solid budget-friendly option if you’re handy and need to replace a worn PTO clutch on a compatible Husqvarna or AYP tractor. It’s not the most durable choice for heavy commercial use, but for residential mowing it offers reliable performance at half the OEM price.
