50 Pack Walk-Behind Wheeled Pre-Cut String Trimmer Line Compatible with Cub Cadet Craftsman Replace#: 490-040-C035 743-0112 731-100,18.5" Long 0.155"

What It Is

This is a 50-pack of pre-cut, walk-behind string trimmer line segments, each 18.5 inches long and 0.155 inches thick. They are designed for use with Cub Cadet and Craftsman walk-behind mowers that use a wheeled trimmer attachment, not handheld string trimmers.

Fitment & Compatibility

• Cross-reference OEM part numbers: 490-040-C035, 743-0112, and 731-100. Check your mower’s manual or current part number against these.
• Diameter: 0.155 inches (0.4 mm). This is a common thickness for residential walk-behind mower trimmer heads. Verify your existing line diameter—using thinner line may underperform, thicker may not fit or damage the head.
• Length: 18.5 inches per piece. This is a standard pre-cut length for many walk-behind trimmer attachments. Measure the slot depth on your trimmer head to confirm it accepts this length.
• Brand compatibility: Advertised for Cub Cadet and Craftsman, but may fit other brands with compatible trimmer heads (e.g., MTD, Troy-Bilt). Always check the trimmer head model, not just the mower brand.
• Mower deck size: Not deck-specific; this is for the trimmer attachment, not the cutting deck. Ensure your mower has a wheeled trimmer attachment (often side-mounted).

Key Things to Know

• Quality: Aftermarket line—not OEM Cub Cadet/Craftsman. At this price point, expect standard nylon performance; may wear faster than premium brands.
• Installation: Simple—just insert one piece into each slot of the trimmer head. No winding or spooling required. Most heads have 2-4 slots.
• Gotcha: Pre-cut line is less flexible than continuous spool line. If your trimmer head is designed for continuous line, these pre-cut pieces may not advance properly.
• Quantity: 50 pieces is a high count. A typical mower uses 2-4 pieces per change, so this pack could last 12-25 refills depending on use.

Should You Buy It

Buy this if you own a Cub Cadet or Craftsman walk-behind mower with a wheeled trimmer attachment and want a bulk, no-fuss supply of pre-cut line. It’s a good value for frequent users who prefer not to cut or spool their own line. Skip it if you need OEM parts for warranty compliance or if your trimmer head requires continuous spool line for proper feeding.
