Flat Idler Pulley 44 50 inch Deck for Cub Cadet MTD Z-Force 44 48 50 S 54-KH 60 LTX1050 ZTL7500 Tank 48 60 L48-KH L60-KH S6031 S6032 02004447 01004101 756-04400 1 Pack

What It Is

This is a flat idler pulley for 44- to 60-inch mower decks on Cub Cadet and MTD zero-turn and lawn tractors. It routes and tensions the deck belt, keeping blade engagement smooth and consistent.

Fitment & Compatibility

Check these three things before buying:

• Deck size & model: Fits Cub Cadet Z-Force 44/48/50/S, LTX1050, ZTL7500, Tank 48/60, L48-KH, L60-KH, S6031, S6032, plus MTD equivalents with 44–60 inch decks. Verify your deck diagram matches.
• OEM part numbers: Cross-reference with 02004447, 01004101, or 756-04400. Aftermarket version (this one) is a direct replacement for these OEM numbers.
• Measurements: Outer diameter should be approximately 4.0–4.5 inches, inner bearing bore 0.5–0.625 inches. Confirm your existing pulley’s OD and bore—this is a flat (non-grooved) idler, not a V-pulley.

Key Things to Know

• Quality note: At $11.88, it’s a budget aftermarket part. Some users report bearing noise after a season under heavy use. Inspect for smooth spin before installing.
• Installation difficulty: Easy—remove belt, unbolt old pulley, bolt on new one. Torque to spec (typically 20–30 ft-lbs). No special tools required.
• Common gotcha: The flat surface can wear unevenly if belt tension is too high. Check belt condition and tension spring before replacing the pulley alone.
• Bearing type: Sealed ball bearing—no greasing needed. If it feels gritty out of the box, return it.

Should You Buy It

If you need a quick, low-cost replacement for a worn flat idler on a Cub Cadet or MTD 44–60 inch deck, this will get you back mowing. It’s fine for light to medium use, but commercial operators or heavy-duty users should expect shorter life than OEM.
