Cub Cadet 490-040-C035 Replacement Cutting Trimmer Line for Walk Behind Wheeled String Trimmers, .155-Inch. Diameter x 18.5-Inch Length, Natural

What It Is

This is a replacement trimmer line for Cub Cadet and MTD-branded walk-behind wheeled string trimmers. The .155-inch diameter x 18.5-inch length line is designed for heavy-duty trimming of thick grass and light brush, typically on larger lawns or commercial properties.

Fitment & Compatibility

Before buying: Measure your existing line diameter and length. This .155-inch line fits most Cub Cadet and MTD wheeled string trimmers with a bump-feed or fixed-line head that accepts .155-inch line. It is not compatible with handheld trimmers or electric units. Check your model number (e.g., 490-040-C035) against your trimmer’s manual or the OEM parts list. This is an OEM Cub Cadet replacement, not an aftermarket universal line.

• Deck size: Fits trimmers with 17–22-inch cutting swaths.
• Brands: Cub Cadet, MTD, Troy-Bilt (same parent company). Will not fit Husqvarna, Stihl, Echo, or Ryobi wheeled trimmers without adapter.
• Measure twice: If your trimmer head uses .130 or .160 line, this .155 may be too thick (won’t feed) or too thin (whips excessively).

Key Things to Know

• Quality: Natural polymer line – durable and flexible, but not as abrasion-resistant as reinforced or twisted lines. Expect good performance on grass, but it will wear faster on gravel or concrete edges.
• Installation: Easy – no tools needed. Remove spool, wind line evenly, feed through eyelets. Watch for winding direction (usually clockwise on Cub Cadet heads).
• Common gotcha: If your trimmer uses a pre-wound spool, this is loose line only. You must wind it yourself. Over-winding can jam the bump-feed mechanism.
• Length: 18.5 feet per pack – enough for about 2–3 full spool refills (depending on head size). Not a bulk spool.

Should You Buy It

Yes, if you own a Cub Cadet or MTD wheeled string trimmer and need a direct OEM replacement. It’s a solid choice for standard lawn trimming, but if you frequently trim against hard surfaces or heavy brush, consider a thicker or reinforced line (.160-inch or serrated). For the price and reliability, it’s hard to beat for everyday use.
