What It Is

This is a pre-cut 18.5-inch long, 0.155-inch diameter trimmer line, sold in an 18-pack, designed to replace the spool-loaded line in walk-behind wheeled string trimmers from Cub Cadet, Troy-Bilt, Craftsman, and Remington. It’s a direct drop-in replacement for OEM part numbers 743-0112 and 731-10080, intended for trimming grass and weeds along edges and fences.

Fitment & Compatibility

Before buying, confirm your trimmer is a walk-behind wheeled model (not a handheld or backpack unit) from one of the listed brands. Check the deck size or model number—this line fits most Cub Cadet, Troy-Bilt, Craftsman, and Remington wheeled trimmers that use 0.155-inch line. The 18.5-inch length is pre-cut to match standard spool sizes; if your trimmer uses a different line diameter (e.g., 0.130 or 0.160 inches) or a continuous spool, this won’t work. Verify your OEM part number matches 743-0112 or 731-10080—these are common on models like Cub Cadet CC4450, Troy-Bilt TB475, Craftsman 77730, and Remington RM155. This is an aftermarket replacement, not OEM Cub Cadet branded, but it’s designed to be a direct fit.

Key Things to Know

• Quality: The 0.155-inch diameter is a medium-heavy line, good for standard grass and light weeds, but may snap faster on thick brush or rocky areas compared to thicker 0.160-inch lines.
• Installation: Very simple—just remove the old line from the spool, thread a new pre-cut piece, and wind it on. No cutting or measuring needed; each piece is exactly 18.5 inches.
• Gotcha: The 18-pack gives you 18 individual lines, which is about 3-4 full spool refills for most trimmers. If you trim a large yard weekly, you’ll go through a pack in a season.
• Compatibility check: If your trimmer uses a “bump-feed” head that requires a continuous line, these pre-cut pieces won’t work—you need a spool that accepts separate lengths.

Should You Buy It

Buy this if you own a compatible walk-behind wheeled trimmer and want a hassle-free, pre-cut line that saves measuring time. It’s a good value for the price, with solid ratings, but skip it if you need a thicker line for heavy-duty weeds or if your trimmer uses a continuous spool system.
