Stens New OEM Replacement Belt for Cub Cadet Most i1042, i1046 and i1050 Series mowers 754-04134, 954-04134

What It Is

This is a replacement drive belt for select Cub Cadet iSeries lawn tractors, specifically the i1042, i1046, and i1050 models. It transfers power from the engine to the deck blades, so if your belt is worn, slipping, or broken, this part restores cutting performance.

Fitment & Compatibility

Check your model number: Fits Cub Cadet i1042, i1046, and i1050 series only—not older or newer models. Verify your mower’s model number (e.g., 13APA1CT056) on the frame or under the seat.

OEM cross-reference: Replaces OEM part numbers 754-04134 and 954-04134. This is a Stens-branded aftermarket belt, not genuine Cub Cadet, but it’s built to OEM specs.

Measure the belt: Before buying, measure your old belt’s length (outside circumference) and width. The correct belt is typically 1/2” wide and about 94” long, but confirm with your model’s manual.

Deck size: Works with 42”, 46”, and 50” decks on these iSeries models. If your deck is smaller or larger, it won’t fit.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand; this belt is reinforced with Kevlar for durability and resists stretching better than budget belts.
• Installation difficulty: Moderate—requires removing the deck or belt cover, routing around pulleys, and using a tensioner tool. Expect 30–60 minutes.
• Common gotcha: The belt routing diagram on some iSeries decks is easy to misread. Take a photo of the old belt before removing it, or look up the routing in your manual.
• Lubrication: No grease or oil needed on the belt itself, but check that all pulleys spin freely and are clean before installing.

Should You Buy It

Yes, if you own a Cub Cadet i1042, i1046, or i1050 and need a reliable, affordable replacement for a worn or broken deck belt. It’s a solid aftermarket option that matches OEM quality at a lower price, but double-check your model and belt length before ordering.
