A ANLEOLIFE .170" Sawtooth Trimmer Line for Walk-Behind Mowers — 440ft 5 lb Heavy-Duty Serrated

This bulk spool supplies a long-lasting serrated cutting cord engineered to stand up to rough growth where standard round string wears out quickly. The .170" diameter and three-layer sawtooth profile deliver more aggressive bite and controlled handling for property maintenance, landscaping crews, and landowners who use walk-behind mowers or high-capacity heads. The large 5 lb roll reduces reload frequency and keeps crews working longer between spools.

How does this sawtooth line perform on heavy brush and weeds?

The serrated three-layer profile is designed to slice through coarse stems, brambles, and dense roadside growth with improved edge retention compared to smooth round cord. The sawtooth edges concentrate cutting force while the heavier .170" gauge resists rapid fraying.

• Aggressive serrated edges for better bite on woody plants
• Extra-heavy .170" diameter for tougher growth and longer wear
• Reduced breakage in thick material versus lighter lines

Will this spool fit my walk-behind mower head?

The line is intended for heads rated to accept .170" trimmer line and for many fixed-line, high-capacity, and walk-behind heads. Always check your mower or head manual for recommended diameters and loading directions before installing.

• Compatible with many popular brands’ .170-rated heads
• Works with fixed-line and high-capacity spool systems on walk-behinds
• Includes built-in cutter on some heads for easier reloads—confirm compatibility

How do I load and manage a 440 ft bulk spool on a worksite?

The spool’s bulk length is ideal for frequent users and maintenance crews: cut measured lengths to fit your head or preload multiple spools for quick swaps. Store the roll in a dry, cool spot and spool only the amount you need to avoid tangles and material stress.

• Cut pre-measured lengths for consistent reloads across machines
• Keep spool coiled and dry to prevent kinks and memory issues
• Measure heads for correct length and use a built-in cutter where available

How long will one spool last compared with standard line?

The 5 lb / 440 ft bulk size lasts substantially longer in heavy-use situations than smaller retail spools, mainly because the thicker serrated profile resists wear and breakage. Actual runtime depends on vegetation density and operator technique, but the bulk supply reduces downtime for reloads.

• 440 ft reduces reload frequency for large properties or crews
• Thicker gauge limits replacement frequency under heavy workloads
• Best used where brush, ditch lines, and field borders are common

This spool is best for landscapers, municipal crews, farmers, and landowners who regularly maintain rough or overgrown areas with walk-behind mowers, fixed-line heads, or heavy-capacity setups. If you need a long-lasting, heavier serrated cord to cut through brambles, tall weeds, and field edges without constant reloads, the Anleolife .170" sawtooth trimmer line is built for that work—just confirm your head’s diameter rating before loading and follow your mower manufacturer’s loading instructions.
