Craftsman has long maintained a prominent reputation in outdoor power equipment, providing accessible cordless and corded string trimmers designed for residential upkeep and on-the-go property maintenance. For mobile landscapers and property caretakers who transport tools between sites, reliable string trimmer line is an essential consumable that directly impacts runtime and efficiency. Running out of line mid-job or experiencing spool jams from unevenly wound line halts work instantly, making factory-wound and precision-molded replacements a cornerstone of seamless yard care. Standard Craftsman weed eater string configurations primarily utilize a slender 0.065-inch diameter line, engineered to balance cutting performance with minimal motor drag across their WEEDWACKER and legacy trimmer lineups.
While each option in this guide supplies line compatible with Craftsman string trimmers, they differ substantially in pack quantities, material formulations such as glass-fiber reinforced nylon versus standard polyamide, included maintenance hardware like caps and springs, and model compatibility spanning modern auto-feed heads to legacy dual-line platforms.

Sold as a craftsman .065 spool 3 pack, each individual spool comes pre-wound with 30 feet of factory-calibrated 0.065-inch line. The total package weighs 4.8 ounces and measures 2.4 by 2.5 by 3.31 inches, creating an exceptionally compact profile that packs effortlessly into mobile field toolboxes or utility totes.
Engineered strictly to original equipment standards, this factory-wound craftsman cmzst0653 configuration delivers reliable functionality and smooth auto-feeding on Craftsman WEEDWACKER models, including the CMCST900, CMESTA900, CMESTE920, and CMCST98020 series. Because the spool is wound under factory tension, it resists the internal binding and cross-layer wedging that often plague hand-wound alternatives. The manufacturer also supports this package with an official 2-year limited warranty, offering peace of mind that aftermarket options cannot match. When packing equipment alongside a craftsman socket organizer in a mobile maintenance vehicle, having genuine factory spools ensures predictable operation on every stop.
This OEM pack is the premier choice for property owners who demand authentic brand specifications and factory warranty coverage for their compatible V20 and corded WEEDWACKER trimmers. However, because it contains only three spools without supplementary wear items like replacement caps or tension springs, it yields to aftermarket utility bundles when trimmer hardware needs rebuilding.

This high-quantity bundle is suited for estate caretakers and travel crews who want to eliminate hand-winding string entirely across an entire cutting season. It ensures continuous trimming without frequent ordering cycles, though its 1.12-pound weight makes it slightly bulkier to store than standard three-spool alternatives.

Pros
- Twisted aerodynamic line profile
- Durable polyamide nylon thread
- Lightweight 5 ounce total pack
Cons
- No replacement cap or spring included
The CMZST065 CMZST0653 String Trimmer Spool Line package, manufactured by Cilivo under model CZ-CMZST065-3P, is a specialized 3-pack replacement designed for Craftsman weedwacker units. Each spool contains 30 feet of 0.065-inch diameter line wound around a high-quality ABS spool body. The entire three-piece assortment weighs 5 ounces and measures 3 by 1 by 0.5 inches.
The defining technical attribute of this craftsman trimmer line 0.065 option is its twisted cord profile. Built from durable polyamide nylon, the twisted design harnesses centrifugal force and improved aerodynamics to reduce air drag while spinning, which helps conserve battery life on cordless trimmers. It fits Craftsman string trimmer models CMCST900, CMCST900D1, CMEST900, CMESTA900, CMESTE920, CMZST98020, CMCST915, and CMEST913. The manufacturer stresses essential safety precautions, noting that operators must wear goggles and long pants to avoid injury from debris and should turn off the power unit before swapping spools. Stashing this set alongside essentials like a craftsman deep socket set in a mobile workshop keeps battery-conscious yard gear ready for action.
This 3-pack is ideal for battery-conscious operators who want the drag-reducing benefits of twisted aerodynamic line without carrying excess hardware. However, because it includes no replacement caps or springs, it gives way to broader kits if your trimmer cap is worn out.

Each spool is loaded with 30 feet of 0.065-inch polyamide nylon line wound onto an ABS spool frame, rated for 110 pounds of tensile strength to withstand rapid centrifugal forces. The listing specifies that this spool for craftsman cmcst900 trimmers also fits models CMESTA900, CMESTE920, CMCST98020, CMEST913, and CMCST915. The manufacturer clearly notes operational limits: this line is engineered specifically for young grasses, requiring operators to step up to bladed attachments when facing dense, woody weeds.

This package is an excellent match for suburban homeowners and mobile workers maintaining manicured lawns who want a spare cap and spring on reserve alongside four fresh spools. It yields to reinforced glass-fiber line or heavy-duty cutting heads when dense overgrowth is present.

Pros
- Dual line auto feed design
- Tool-free replacement process
- Restores older Craftsman trimmer models
Cons
- Line length and spool count not listed
- Incompatible with modern CMCST900 series
The 71-99006 Weed Eater Spools Compatible from Eyoloty addresses a completely different generation of Craftsman equipment. While modern cordless trimmers use single-line spools, this replacement is designed specifically for dual-line auto-feed systems found on legacy Craftsman models. The listing does not specify exact line length, package dimensions, or total item weight.
This dual-line replacement uses a 0.065-inch line diameter to deliver clean cutting performance across older Craftsman string trimmers. It is compatible with models 71-30378, 71-30383, 71-98981, 71-98982, and replaces the craftsman 71-99006 spool part number. It features solid construction engineered for tool-free installation, allowing users to refresh legacy equipment without the frustration of manually winding two independent strands onto an empty core.
This product is exclusively intended for owners of vintage or legacy dual-line Craftsman trimmers. Because its mechanical layout differs entirely from the modern CMZST065 housing, it will not fit V20 or modern corded WEEDWACKER models like the CMCST900.
Before you choose
How to Choose the Right Craftsman Trimmer Spools
Selecting the correct spool begins with matching the exact model number of your trimmer against the spool housing. Modern Craftsman battery-powered and corded units, including the CMCST900, CMESTA900, CMESTE920, and CMCST98020 series, accept the single-line CMZST065 format. Installing a vintage dual-line spool like the 71-99006 on these newer models is physically impossible due to core diameter and feed-eye differences. Always check the model stamped on your trimmer shaft before purchasing replacement line.
Another major decision is choosing between genuine OEM construction and aftermarket compatibility bundles. The CRAFTSMAN Genuine OEM String Trimmer Line offers factory-wound precision and an official 2-year warranty, making it the safest pick for strict factory compliance. On the other hand, aftermarket packages like the Denkuhin 6+2+2 kit, the YWTESCH 11-piece set, and the Kaberalty 4+1+1 kit provide extra CMZST120SC caps and replacement springs, which are invaluable when working away from home where lost or damaged parts could halt a job.
Material construction and line geometry also influence trimming performance. While standard line uses polyamide nylon, aftermarket options like Denkuhin and YWTESCH blend PA6 nylon with 30% glass fiber to achieve over 100 pounds of tensile strength. Alternatively, the Cilivo CZ-CMZST065-3P employs a twisted line profile to lower aerodynamic drag, helping preserve battery life on cordless V20 trimmers. For light trimming on manicured turf, standard nylon is sufficient, but tougher borders benefit from reinforced or aerodynamic line styles.
Finally, consider packing weight and travel requirements when selecting pack size. A 3-pack or 4-pack of pre-wound spools weighs between 4.8 and 8 ounces, sliding easily into glove compartments or compact travel toolboxes. Larger bulk kits with 8 spools deliver maximum autonomy for multi-day maintenance trips, but add extra bulk and weight to your gear load.
Questions people ask
FAQ
Which spool fits my Craftsman trimmer?
The correct spool depends on your trimmer generation. Modern Craftsman WEEDWACKER models, such as the CMCST900, CMESTA900, CMESTE920, and CMCST98020, use 0.065-inch single-line spools under part numbers CMZST065 or CMZST0653. Older Craftsman models, such as 71-30378, 71-30383, 71-98981, and 71-98982, require the 71-99006 dual-line spool. Review the model label on your tool shaft to confirm compatibility before purchasing.
What is the difference between genuine Craftsman CMZST0653 and aftermarket replacements?
Genuine Craftsman CMZST0653 spools are factory-wound by the original equipment manufacturer and include an official 2-year limited warranty. Aftermarket options, such as those from Denkuhin, Cilivo, and YWTESCH, often supply additional replacement caps (model CMZST120SC) and springs, or incorporate alternative materials like glass-fiber reinforced nylon or twisted line profiles.
Can 0.065 trimmer line cut through thick brush?
A 0.065-inch trimmer line is engineered for light to medium residential trimming, such as lawn edging and cutting young grass. Manufacturer listings specifically note that 0.065 line is not intended for thick, woody brush or heavy weeds. Cutting dense vegetation with 0.065 line will cause rapid line wear, frequent feeding, and potential line breakage.
Why do some replacement kits include caps and springs?
Trimmer head caps and internal springs are subjected to continuous friction and vibration against soil, curbs, and rocks. Over time, plastic tabs on the cap can snap or wear down, causing the cap and spool to fly off during operation. Bundles that include replacement CMZST120SC caps and springs allow you to rebuild worn trimmer head hardware on-site.
How do pre-wound spools prevent trimmer head jamming?
Pre-wound spools are wound under controlled mechanical tension at the factory, ensuring that the 30 feet of line lays in flat, parallel rows. When lines are wound by hand, overlapping coils can wedge beneath each other under tension, preventing the automatic feed mechanism from releasing fresh line when the trimmer spins.
