Best Universal Weed Eater Heads for Most Trimmers
As an Amazon Associate we earn from qualifying purchases.
A universal weed eater head is a replacement head that the listing says fits many trimmer brands, usually through a threaded adapter, a bump-feed mechanism or a set of metal blades. The main choice is between a fixed-line or bump-feed string head and a steel blade head that cuts with razor teeth. Before buying, match the head to your trimmer shaft and arbor size, then pick the line diameter or blade type that suits the grass and weeds you cut. The eight heads below are the ones whose listings describe a universal head or universal trimmer fit.
Quick answer
- For string trimmers, choose a head whose listing names your trimmer brand or says it fits most straight shaft or cordless models.
- For a bump-feed head, the Weed Warrior Autowinder II and the Toussaint head list a tap-to-advance feed. Check the listing for the line diameter it accepts.
- For heavy weeds and brush, the steel blade heads (Refitial, Gashwer and RAHQHD) are the group the listings describe as built for thicker growth, with a universal adapter kit included.
- Check the thread and shaft before you order. Several listings say the head only works with a specific shaft direction or bolt size.
How to choose a universal head
Start with the trimmer, not the head. Most string trimmer heads attach to a threaded shaft, and the listings give the thread rule that matters. The Toussaint listing says the trimmer shaft must turn counterclockwise and that the kit covers left-hand thread bolts and nuts in several sizes, including M8x1.25, M10x1.25 and M7x1.0. The Refitial and RAHQHD listings describe a one-inch gearbox and a one-inch central hole for straight shaft gas trimmers. If your trimmer has a different arbor, the adapter kit in the package is the part to check.
Next, decide between string and blade. A string head lets you cut with nylon line that you replace or feed as you go. A steel blade head cuts with metal teeth and is meant for stalks, brush and thicker growth. The Toussaint and Husqvarna listings describe string heads for trimming, and the 6-blade kit listing says its carbide blade is not for cutting trees or wood. Pick the type that matches the job, not the one with the most parts in the box.

String heads
Husqvarna T35 string trimmer head
The Husqvarna T35 is the only head in this group that the listing describes as a Husqvarna product, and it is sold as a replacement head for Husqvarna straight shaft trimmers in the 100 to 500 series. The bullets also say it is compatible with most Echo, Stihl and RedMax straight shaft trimmers. It comes pre-wound with .095-inch line and the listing states it holds 28 feet of that line. The split spool is said to reduce tangling, and the arrows on the spool show the direction to wind the line. The spool comes off with the cap, so you do not need to turn the trimmer upside down to reload it. This is a good pick if your trimmer is already a Husqvarna or a common straight shaft brand and you want a head that loads without fuss.
Weed Warrior PivoTrim fixed-line head
The PivoTrim is a fixed-line head that accepts .080-inch and .095-inch line, according to its bullets. It is listed as fitting most trimmer models, and the listing says premium pre-cut line is included. The bullets state that it cuts with six pivoting lines to prevent breakage, but the product title describes a 3-line design. The two statements do not agree, so read the listing carefully and confirm the line count with the seller before you rely on either. The material is listed as metal. If you prefer a fixed head with no spool to wind, the PivoTrim and the Push-N-Load are the two Weed Warrior options in this group.
Weed Warrior Autowinder II bump-feed head
The Autowinder II is a bump-feed head. Each tap of the trimmer on the ground advances the line, and the listing says you can reload the line without taking the whole head apart. The listing says it holds up to 16 feet of .080, .095 or .105-inch line. The title and bullets name a long list of compatible brands, including Echo, Stihl, RedMax, Ryobi, Cub Cadet, Weed Eater and MTD, and it is described for both gas and select cordless trimmers. The bullets call it durable and heavy duty, but no specific material or weight is given in the pack, so this post does not add one. This head suits a user who wants a bump feed and a simple reload routine.
Weed Warrior Push-N-Load two-line head
The Push-N-Load is a two-line fixed head with no spool. You push precut line into the head, and the listing says it accepts line from 0.050 inch to 0.155 inch. The head is described as glass-filled nylon, and the package includes six precut strips of 0.095-inch line plus an adapter kit. The listing says it works with gas and battery string trimmers. Because the line range is wide, match the strip size to your trimmer and to the grass you cut. A two-line head is simple to load, but it is not the head to use for thick brush.
Toussaint universal bump-feed head
The Toussaint head is a bump-feed head with a dual color line. The listing describes a metal and impact-resistant plastic body and a pivoting line design that is meant to reduce line wear and breakage. Installation depends on the thread of your shaft. The listing says the trimmer must turn counterclockwise and that the head works only with a left-hand thread. It includes bolts and nuts in sizes M8x1.25, M10x1.25 and M7x1.0, and the listing tells you to compare the existing bolt or nut on your shaft before you start. The brand list covers Echo Speed Feed 400, Ego, Ryobi, Husqvarna, Craftsman, Shindaiwa, Honda, Redmax and others. If your trimmer matches one of these brands but not the thread, the head will not fit.
Steel blade heads
Refitial 6-tooth steel cutterhead kit
The Refitial kit has two 6-tooth steel cutterheads and two adapter kits. The bullets say it is built for straight shaft gas trimmers with a one-inch gearbox and that the blades are made of alloy steel. The listing describes a six-leaf head that rotates 360 degrees. Each adapter kit includes thrust washers, a T-wrench, a flange nut and a screwdriver. The listing tells buyers to check the mower model before purchase and to add the adapter kit the first time they install the blade. Wear high-top shoes, eye protection and gloves during installation, as the listing advises. This kit suits the reader who needs a steel head for grass and light brush.
Gashwer steel head with carbide blade
The Gashwer package combines a six-blade steel razor head and a 9-inch, 36-tooth carbide-tipped blade. The listing says the two blades are forged from 65Mn manganese steel. It fits a standard one-inch arbor and includes two full sets of adapter kits, with thrust washers, rider plates, collar nuts and wrenches. The bullets name Stihl, Husqvarna, Ego, Oregon and Hitachi as compatible brands. The listing describes the head for residential lawn work, garden weeding and orchard pruning, and it says the kit has a one-year warranty. Because the package includes a carbide blade, it covers a wider range of growth than a simple grass head. The listing does not say it cuts wood, so use the carbide blade for brush and branches only as the listing describes.
RAHQHD steel head with carbide blade
The RAHQHD kit is similar: six steel razors plus a 9-inch, 36-tooth carbide-tipped blade, with a central hole of one inch. The listing says it works with most straight shaft gas trimmers that have a one-inch gearbox and that it includes two adapter kits. It names Husqvarna, Stihl, Ego, Oregon and Hitachi for the universal adapter, and it lists Coocher, DeWalt brush trimmers and Forester brush blades as compatible. The bullets advise avoiding stones and solid objects because they can blunt or break the blade, and they recommend ankle-high shoes, jeans and safety glasses. A one-year warranty is stated. This kit is a good second option if your trimmer uses the same one-inch arbor.
How to pick between the blade heads
The Gashwer and RAHQHD kits are close in content. Both include a steel razor head and a carbide blade with the same tooth count and blade diameter. The choice comes down to the adapter kit that matches your trimmer, and the warranty and support terms in each listing. The Refitial kit is a two-cutterhead set with no carbide blade. If you cut brush more than you cut grass, the carbide-blade kits are the group to compare.
Product picks, one by one
Each block below uses only the facts in that product’s listing. Read the full listing before you buy, because the bullets are the source for the fit and line details shown here.
Husqvarna 537388101 T35 string trimmer head
Pick this head if you own a Husqvarna straight shaft trimmer or a common Echo, Stihl or RedMax straight shaft model. The listing says it arrives pre-wound with .095-inch line and that the spool comes off with the cap for reloading. The split spool and directional arrows are the features to look for if tangling has been a problem with your current head.
Weed Warrior PivoTrim 17233 fixed-line head
This is a fixed-line head for trimmers that accept .080 or .095-inch line. The listing says it fits most trimmer models and includes pre-cut line. Confirm the line count from the full listing, since the title and bullets describe it differently.
Weed Warrior Autowinder II 17561 bump-feed head
This is the bump-feed option in the Weed Warrior line. The listing says each tap advances the line and that you can reload without taking the head apart. It lists up to 16 feet of .080, .095 or .105-inch line and names a long list of brands, so it suits a reader who owns one of those trimmers and wants a bump feed.
Weed Warrior Push-N-Load 17234 two-line head
The Push-N-Load skips spool winding. You push precut line into the head. The listing gives a line range from 0.050 to 0.155 inch and includes six pre-cut strips of 0.095-inch line plus an adapter kit. It is a simple head for light to medium grass and weeds.
Refitial DPTZ-01 steel cutterhead kit
This kit is for owners of straight shaft gas trimmers with a one-inch gearbox. It includes two 6-tooth steel cutterheads and two adapter kits, so it is useful if you want a spare head or need to fit two trimmers. The listing says to check the mower model before buying and to fit the adapter kit on first use.
Gashwer steel head with 9-inch carbide blade
This is the kit to compare for mixed work. It pairs a six-blade steel head with a 9-inch, 36-tooth carbide blade, includes two adapter kits and a one-year warranty, and names several straight shaft brands. Use the carbide blade for brush and small branches only, as the listing describes the head for residential and orchard clearing.
RAHQHD steel head with 9-inch carbide blade
This kit matches the Gashwer in blade count and blade size, with a one-inch central hole and two adapter kits. Its listing includes a one-year warranty and a list of compatible brands. The bullets advise avoiding stones and wearing ankle-high shoes and eye protection.
Toussaint universal bump-feed head
Choose this head only after you have checked the shaft direction and the bolt or nut on your trimmer. The listing requires a counterclockwise shaft and a left-hand thread, and it lists the bolt and nut sizes in the kit. Its brand list covers Echo Speed Feed 400, Ego, Ryobi, Husqvarna and Craftsman, among others.
Mistakes to avoid
- Buying a head without checking the shaft thread. The Toussaint listing names a counterclockwise shaft and a left-hand thread, and a wrong thread will not seat.
- Choosing a line diameter the head does not accept. The Weed Warrior PivoTrim takes .080 and .095 line, and the Push-N-Load takes 0.050 to 0.155 line, so match the line to the head listing.
- Running a steel blade head into stones or solid objects. The RAHQHD listing warns that stones can blunt or break the blade.
- Trusting a title over the bullets. The PivoTrim title and bullets disagree on the number of lines, so read the full listing.

FAQ
Does a universal weed eater head fit every trimmer?
No. The listings say “universal” in different ways. Some name a list of brands, some describe a straight shaft fit, and the Toussaint listing requires a specific thread direction and bolt size. Check the brand list and the shaft thread in the listing before buying.
Which head should I use for thick brush?
The listings for the Gashwer and RAHQHD kits describe a 9-inch carbide-tipped blade for brush and small branches, and both include steel razor heads. The listing for the Refitial kit describes steel cutterheads for heavy weeds. The 6-blade kit listing says its carbide blade is not for cutting trees or wood.
What line size do the string heads take?
The Husqvarna T35 is pre-wound with .095-inch line and is listed as compatible with .065 to .105 line. The Autowinder II accepts up to 16 feet of .080, .095 or .105-inch line. The PivoTrim accepts .080 and .095 line. The Push-N-Load accepts 0.050 to 0.155 line, with six pre-cut strips of 0.095 included.
Are the blade heads sold with an adapter kit?
Yes. The Refitial, Gashwer and RAHQHD listings all say an adapter kit is included, and the Refitial and RAHQHD listings say two kits are included.
Do these heads need a special tool to install?
The listings mention T-wrenches, L-wrenches, screwdrivers and wrenches, which are included with the blade kits. The Husqvarna and Autowinder II listings describe reloading or changing line without a special tool.
How do I keep a blade head safe to use?
Follow the listing: remove power before changing a blade, wear eye protection and ankle-high shoes, keep the guard in place, and avoid hitting stones or solid objects. The RAHQHD and Gashwer listings give these instructions.
Bottom line
Choose the head by the shaft you own. If your trimmer is a Husqvarna or a common straight shaft brand, start with the Husqvarna T35 or the Autowinder II. If you cut thick weeds and light brush and your trimmer has a one-inch gearbox, a steel blade kit such as the Gashwer or RAHQHD is the group to compare. Confirm the thread, the arbor and the line or blade size in the listing, then order the head that matches those three things.
