Quintillus H02 Weed Eater Head Universal Trimmer Head String Trimmer Head Bump Feed Weed Wacker Head Grass Trimmer Head Replacement for Weed Warrior, Echo, Husqvarna, Comes with .095 Trimmer Line

What It Is

The Quintillus H02 is a universal bump-feed trimmer head designed to replace factory heads on gas and electric string trimmers. It comes pre-loaded with .095-inch trimmer line and is intended for residential yard work, edging, and light-to-medium weed trimming.

Fitment & Compatibility

Before buying, check three things:

• Shaft size – The H02 fits most trimmers with a 10mm x 1.25 LH threaded shaft, plus adapters for 7/16″-20 UNF (common on Echo, Husqvarna, and Ryobi). It includes 4 adapters and 2 washers for universal fit.
• Line diameter – Pre-loaded with .095″ line. This head accepts .080″ to .105″ line. If your trimmer recommends thinner line (e.g., .065″), the head may be overkill and cause engine bogging.
• OEM vs aftermarket – It’s a direct replacement for most Weed Warrior, Echo, Husqvarna, and similar brands, but not a perfect fit for all models. Measure your existing head’s diameter (this one is ~5.5″) and check your trimmer’s manual for shaft thread specs.

Key Things to Know

• Installation is straightforward – No tools required for line loading. The bump-feed mechanism works reliably, but some users report occasional line tangling if you use thicker line.
• Durability is decent for the price – The plastic housing holds up to normal use, but hitting rocks or curbs repeatedly can crack the head.
• Line advancement – The bump-feed can be inconsistent on the first few uses; it may need a few taps to settle. Pre-winding the line tightly helps.
• Adapter fit varies – Even with the included adapters, some trimmers (e.g., older Echo models) may require a separate adapter or slight modification to the shaft.

Should You Buy It

Buy this if you need an affordable, universal replacement head for a gas or electric trimmer with a standard threaded shaft and you’re comfortable with minor fitment tweaks. Skip it if you have a high-end commercial trimmer that demands OEM parts, or if your trimmer uses a non-threaded (e.g., speed-feed) head system.
