Arnold OEM-754-04060 42" Deck Drive Belt

What It Is

The Arnold OEM-754-06040 is a 42-inch deck drive belt designed to transfer power from the engine pulley to the mower blades on select riding lawn mowers with a 42-inch cutting deck. It’s a direct replacement for OEM part numbers 754-06040 and 754-04060, commonly used on Craftsman, Husqvarna, and Poulan models.

Fitment & Compatibility

Before buying, verify three things:

• Deck size – This belt fits only 42-inch decks. Measure your current belt length (end-to-end, flat) or check your owner’s manual for the OEM part number.
• Model/brand – Confirm your mower’s make and model. This belt replaces OEM numbers 754-06040 and 754-04060, and fits many Craftsman (e.g., 917 series), Husqvarna (e.g., YTH22V46), and Poulan Pro models. Check Arnold’s online cross-reference or your manual.
• Belt dimensions – It’s 42 inches long, 5/8-inch wide, and uses a standard “A” section (or “4L” profile). Measure your old belt’s width and length to avoid a mismatch.
• OEM vs. aftermarket – This is an Arnold aftermarket belt, not a branded OEM part. It’s built to OEM specs but may have slight differences in material or flexibility. If your mower is under warranty, using an aftermarket belt could void coverage.

Key Things to Know

• Quality – Made from reinforced rubber, it’s durable for residential use but may not last as long as a premium Kevlar belt under heavy or commercial conditions.
• Installation difficulty – Easy to moderate. You’ll need to release deck tension (usually by loosening an idler pulley), route the belt around all pulleys, and re-tension. No special tools required, but a pair of pliers helps.
• Common gotchas – The belt can slip if the idler pulley spring is weak or if pulleys are worn. Check all pulleys for wobble or rust before installing. Also, route it exactly as shown in your deck diagram—misrouting causes poor cutting or belt damage.
• Break-in – Expect some initial squeaking or dusting for the first 30 minutes of use. This is normal and should stop as the belt seats.

Should You Buy It

Buy this if you need a reliable, budget-friendly replacement for a 42-inch deck belt on a Craftsman, Husqvarna, or Poulan riding mower. It’s a solid choice for residential homeowners who mow an average-sized lawn and want a direct fit without paying dealer prices. Skip it if you have a commercial mower, need a heavy-duty belt for frequent use, or require a genuine OEM part for warranty compliance.
