8TEN Belt for AYP Husqvarna LT 152 1942 LTH 1942 2142DR YTH 18542 2042 532429636 John Deere 116 180 185 240 M84136 (101 1/2" x 1/2")

What It Is

This is a replacement drive belt (101 1/2" x 1/2") designed for select AYP, Husqvarna, and John Deere lawn tractors. It transfers power from the engine pulley to the cutting deck and/or transmission, enabling blade engagement and mower movement.

Fitment & Compatibility

Before buying, confirm three things:

1. Measure your old belt – This belt is 101.5 inches long and 1/2 inch wide. Any deviation (especially length) will cause poor fit or slipping.
2. Check your model number – It fits AYP/Husqvarna models like LT 152, 1942, LTH 1942, 2142DR, YTH 18542, 2042 (and OEM part 532429636). For John Deere: 116, 180, 185, 240 (OEM M84136). Not all Husqvarna or Deere tractors use this size.
3. Deck size matters – Typically fits 42-inch and 48-inch decks, but verify your specific mower’s belt routing diagram (often under the deck or in the manual). This is an aftermarket belt, not OEM.

Key Things to Know

• Quality is decent for the price – 4.3 stars from 333 reviews suggests reliable performance for residential use. Not heavy-duty commercial grade.
• Installation can be tight – You’ll need to remove the deck or release the tensioner to route the belt correctly. A belt routing diagram helps; take a photo before removing the old one.
• Common gotcha: wrong length – Double-check your old belt’s length. A 1/2-inch difference can cause slipping or failure. Measure the actual belt, not the deck size.
• Not for zero-turn or older Deeres – Only fits the specific models listed. Cross-reference with your mower’s deck part number.

Should You Buy It

Yes, if you have one of the listed Husqvarna or John Deere models with a 42-48" deck and need a budget-friendly replacement for light to moderate residential mowing. Skip it for heavy commercial use or if you need an exact OEM fit—consider a genuine Husqvarna or Deere belt instead.
