What It Is

This is a flat idler pulley (2-pack) that guides and tensions the mower deck belt on select MTD, Cub Cadet, Murray, and Toro lawn tractors. It’s used on mid-to-large deck sizes (42–54") where the belt routes around a flat, non-grooved pulley surface—common on stamped deck spindles.

Fitment & Compatibility

Before buying, verify:

• Deck size & belt path: Works on 42", 46", 50", and 54" decks that use a flat idler (not a V-groove pulley). Check your deck’s belt diagram.
• Model numbers: Fits Cub Cadet GT950H, LT-1450, GT2150, GT5024, GT1054; also MTD, Murray (300920), Toro (112-3687, 62-4540). Not universal—cross-check your OEM part number.
• Physical specs: 3.5" outer diameter, 0.5" bore (for a 1/2" bolt), 0.375" wide flat belt surface. Measure your old pulley and bolt diameter to confirm.
• OEM vs aftermarket: This is a non-OEM replacement. It matches the original fit but may use different bearings or seals—expect shorter lifespan than OEM in heavy use.

Key Things to Know

• Bearing quality: Aftermarket bearings are often sealed but may not be as durable as OEM. If you mow rough terrain or tall grass, consider OEM for longer life.
• Installation difficulty: Easy—remove one bolt, swap pulley, re-tension belt. No special tools needed. Takes 10–20 minutes.
• Common gotcha: The bore may be slightly tight on some bolts. Use a light file or sandpaper to ease fit if needed. Also, check belt tension after install—too loose causes slipping, too tight wears bearings.
• 2-pack value: You get two pulleys for ~$17. If only one is bad, keep the spare for future replacement or use both if both are worn.

Should You Buy It

If you have a compatible MTD/Cub Cadet/Toro tractor with a flat idler pulley and want a budget-friendly fix, this 2-pack is a solid choice for light-to-medium duty mowing. For commercial or heavy-use decks, spring for OEM pulleys—they’ll hold up longer under constant stress.
