A Weed Whacker has varied names: String Trimmer, Backyard String Trimmer, Tree Pruner, Brush Cutter, Weed Eater, and many others. As different articles have aptly identified, these versatile backyard instruments include varied cc-power ranges, electrical versus gasoline, and 2-stroke versus 4-stroke capabilities. However what has not been addressed is using a “BLADE” on such a software for all of the versatile work a blade can carry out within the backyard setting.


A round noticed Blade particularly made for and hooked up to a Weed Whacker provides the next versatility makes use of within the backyard setting:

1. Tree trimming (aka Pruning) which in lots of circumstances truly works higher than utilizing a cumbersome heavy chain noticed for pruning for the reason that round blade might be wielded on the finish of a lighter longer 6 foot Weed Whacker shaft for reaching up into bushes. Such a blade can usually lower a tree department/ limb as much as the diameter of the blade offered you narrow from either side of the limb.

2. A blade can be utilized for clearing massive patches and even acreage of heavy thick wooden inventory brush and sticker brambles (aka: Blackberry sticker bushes) the place a typical string line spool can be a lot too weak to chop by way of adequately.

3. Hedge trimming is a dream with a blade hooked up to a Weed Whacker; the hedging motion is quicker and fewer jagged as in comparison with a typical hedging software. So in conclusion, a blade hooked up to a Weed Whacker augments your widespread commonplace string trimmer right into a full-on chain noticed, hedge trimmer, and huge acreage clearer of wooden inventory weed, saplings, and heavy tall progress brambles (ergo, Black Berry bushes).


Every Weed Whacker in the marketplace is completely different and so every proprietor of their explicit Weed Whacker should contact their respective Weed Whacker Producer to inquire about BLADE attachment {hardware}. Most electric-powered variations are UNDER powered for dealing with a Blade so will most likely NOT have blade attachment {hardware} accessible. However, most gasoline powered Weed Whacker’s can have Blade attachment {hardware} accessible. Blade attachment {hardware} usually consists of a typical blade guard together with a couple of small metallic components that match on (slide onto) the little threaded shaft that the String Spool screws onto. These little items of {hardware} will include the decrease half that can have a raised circle in regards to the measurement of a typical 25 cent piece (quarter) or as small as a nickel (5 cent piece). This raised circle is how the opening within the heart of the Blade matches on, then the higher half {hardware} piece variously referred to as “the cap piece” is utilized on the highest of the blade, then a nut that’s screwed on high of the cap, adopted by a cotter pin.

The outlet within the blade is called the ARBOR Gap. So you will need to know your “Arbor Gap” {hardware} diameter so as to match the blade’s Arbor Gap to your {hardware} when buying Blades on your Weed Whacker. Essentially the most commonplace Arbor Gap diameters within the trade are 1″, which is identical as 25.4mm, but in addition 20mm as effectively. From my expertise I’d say roughly 90% of all blades match these two widespread ARBOR HOLE diameters. (Notice: there are some Arbor Holes in these a lot lesser used diameters: 0.75in & 0.50in). SPECIAL NOTE: A desk noticed blade ought to by no means be used on a Backyard String Trimmer as such blades are extra brittle and constructed for under as much as 3,450 rpm. Such blades can shatter when hitting a rock or one thing very laborious which might be a security concern not protected by the hooked up blade guard. Backyard String Trimmer blades are particularly constructed for 10,000+ rpm and are manufactured with a extra malleable versatile metallic.


Blades usually include metal enamel or CARBIDE enamel. Carbide is effectively value contemplating since a Carbide Tipped (enamel) blade reputably can last as long as 10 occasions longer than a typical metal blade however value nowhere shut to 10 occasions more cash. In truth, a Carbide tooth blade usually would not even value twice as a lot for five to 10 occasions the longevity over plain metal (sustaining sharpness for continued reducing energy is the important thing to a blades worth in relation to value). It must be famous that Carbide isn’t actually simply sharpened however metal might be. Nevertheless, it must be additionally famous that the worth of those metal blades makes them extra of a throw away merchandise as soon as used up for the reason that value to re-sharpen (in time or cash) is often greater than the price of a brand new blade.


Commonplace Weed Whacker blades are available in varied types:

1. THREE-PRONG or five-prong for easy comfortable inexperienced weed reducing. Every massive prong has a leading edge relatively than precise enamel. The deeper inside most a part of every prong doesn’t typically get the identical reducing time because the periphery a part of every prong so dulling happens in an imbalanced method. Such a blade won’t be appropriate for pruning bushes or hedging, nor for reducing heavy obligation wood-stock kind weeds, brush, or brambles. Such a blade is the most cost effective and dulls the quickest because it spreads its reducing floor over solely three to 5 reducing edges and solely is available in primary metal, not carbide.

2. Thirty (30) to Forty (40) TEETH Blade: That is the following step up in Weed Whacker blade decisions. Clearly 40 enamel presents considerably extra combination reducing floor than the blade kind talked about above (3-prong). Such a blade could be very satisfactory for reducing heavy inventory weeds (e.g. tumble weeds), heavy thick brush and blackberry kind sticker brambles however will not be appropriate for Pruning or Hedging. It must be added that these kind blades should be sharp, in any other case the enamel are inclined to seize and tug wooden inventory weeds when uninteresting. The explanation Pruning and Hedging will not be appropriate for this kind blade is simply too few enamel make this blade are inclined to seize inside inexperienced moist tree limbs when pruning and make it are inclined to tear and create jagged-tugging-yanking cuts on a hedge relatively than easy and enticing cuts. Such a blade usually is available in plain metal that dulls shortly however some are actually accessible in carbide tipped enamel as effectively.

3. Eighty (80) to at least one hundred (100) TEETH Blade: That is the very best stage within the Weed Whacker Blade decisions. It must be clear now that the extra enamel you’ve got reducing, the extra combination reducing floor space you might be making use of to the job at hand. As well as, an 80 tooth blade prices more cash to make as in comparison with a blade with half as many reducing enamel as talked about in (2) above (40 enamel). However the fee isn’t usually rather more if in any respect for having 80 enamel over 40 enamel. The 80 plus enamel blade presents essentially the most versatility, stays sharper longer and is the most effective worth for the buck. The 100 enamel kind blade is the best possible worth since if presents 25% extra reducing floor space (enamel) over an 80 tooth blade.

The one primary consideration is that the standard 80 tooth blade is available in Eight inch diameter that matches with the protection blade guard ON your Weed Whacker, and the 100 tooth kind blade is generally 9 to 10 inch in diameter and due to this fact won’t enable a blade guard to suit. We advocate that the utmost measurement diameter blade be restricted to 9 inches until you’ve got a really highly effective Weed Whacker, in any other case the massive circumference of the biggest blades can bathroom down the motor. So in conclusion: 8″ and 9″ diameter blades are greatest, provide essentially the most combination reducing floor, due to this fact keep sharper longer, and provide essentially the most versatility of jobs within the backyard. NOTE: We predict Carbide enamel are so definitely worth the small additional buy value that we’d say a 40 tooth carbide blade can be beneficial over an 80 tooth plain metal any day of the week. However the 80 tooth or 100 tooth blade with Carbide Tooth is the best possible there may be.
