Grass Gator 4600 Heavy Duty Fixed Blade Trimmer Head Replacement | Universal Fit for Straight & Curved Shaft Gas Trimmers | 11.5 Inch Cutting Swath | 3 Tough Nylon Blades | Easy Load

First of all I hate doing yardwork, I fired my gardener to save money and decided to do it myself. I absolutely hate Weedwhacker’s because every 5 to 10 minutes I would have to keep pulling out the line. This was cheap so I thought I would give it a try. I almost didn’t buy it because of the negative reviews. The only thing I can think of is that these people installed it incorrectly. There are instructions for two different types of weed whacker’s straight shaft and curved make sure you install it correctly. I had low hopes for it. But after five minutes of using it on some extremely tall weeds and bush I was amazed. It just trucks through all of the thick stuff, it is extremely durable! I mean I banged the crap out of it on rocks and bricks and dug it into the ground a few times and the blades didn’t break. All they do is wear down evenly meaning that the blades just get shorter and shorter. After using it for about 45 minutes straight I have about half the blades left. I’m just going to buy more blades. I didn’t have to once fix it or anything. The blades will probably last forever as long as you don’t hit them on anything hard like rocks or bricks or concrete like I did. Don’t think about it just get it you will love it. And never go back to line again!

I will never go back to string fed. Thought about the metal ones but decided to go with plastic first, glad I did. These are great for hitting the fence line and rock boarders. We have a new house with a garden that has grown wild and I kind of let it go. It's much easier to clear the whole garden when you don't have to restring every 5 minutes. I went through 2 tanks of gas before taking this picture, I hit a lot of rocks on purpose just to test out these plastic blades. They held up really well, I'm going to buy a packet of replacement blades because I have a lot of Rock boarders. It should be noted that proper PPE is a must there is no shield guard and sticks rocks and even plant material will hit you with quite a bit of force. Also chicken wire doesn't stand a chance against these blades.*** update***After three uses the spacer (weak piece of plastic) failed utterly. love the blades but the housing for them is weak and melts at higher temperatures common with ryobi trimmers. Searching for a better housing (metal would be best)

Welp, where do we start here. So, as a typical male, I didn't read the manual first... I spent a good 5 hours trying to get the trimmer head off my TroyBilt (since mine didn't have a locking hole to turn it off) and had to talk to their customer service (after breaking part of the gear housing)... I figured the head had to come off. Finally got the stupid thing apart, then realized it wouldn't fit correct. Well, what do you know... I decided NOW was the time to read the instructions. And sure as sh!t, they weren't kidding. No tools needed. Super easy install. So after breaking my gear housing, breaking the locking washer so I could pull the head off, I had to put it back on, then simply install the new head. I guess I should start listening to the females in my life. Anyway, I tested it out some and it works good. Nailed the chain link a few times and it didn't break anything. Tried it along some wood trim (gently) and it didn't chew it apart. No more string. Thank God.Oh, it didn't come with three extra blades either or I would have given 5 stars. Unless they consider the three it comes with a bonus. I will update in a few weeks of putting it to use.

This is the worst product I’ve ever ordered off Amazon after assembling I started weed eating about five minutes in the cap busted blades were flying everywhere thank God they missed me the vibration from the weedeater tore a sore and my hand before I can get the weedeater off this is the worst product I’ve ever ordered in my life and I would appreciate a full refund I do hope I didn’t have to miss a day of work Due to the sore since I work with my hands

The blades are not as durable as I had hoped. In fairness, I put this add on through severe paces with my Husqi, chopping blackberry, poison ivy, and virginia creepers with pent up vengeance. In one afternoon the blades were noticeably worn and dulled, but still cutting. I would probably have gone through half a spool of line in the same time.My assessment is that the cost of replacement blades should be compared to the cost and hassle of replacing line since they will both wear out. The long vines and weeds got wound up around the head equivalent to the line spool. When contacting the occasional fence wire or woody shrub, these blades really chatter and naturally are less forgiving than line since they cannot expend material on contact as easily.In the end, if you have a row of predictable medium density weeds, this head will perform better than line. But for really heavy work use a metal blade on your trimmer.

This works much better than a triblade brush cutter for most weeds, and you can get it close to a fence or wall.It doesn't do well for thick woody plants like Multiflora Rose or saplings, a forester 7" "chainsaw link" blade does much better for thick woody plants like those.Installation was super easy, the required hardware (a reverse thread nut) was included for mine.Tall grass and viney plants wrap themselves around the head occasionally, but it's no more than with any other brush cutter.I tried three different guards, and it still spit chunks of vegetation at me. A brush cutter guard worked best.Overall, I'm very satisfied.

I have an old echo straight shaft that I was able to install a different brand on. This head works great, the trimmer just isn't what it used to be. I also have a newer curved shaft Echo which I did install this on. Overall it works well, I just exceeded its capacity by attacking a 1/4" vine maple. I had the metal blades on instead of the plastic ones - those or useless - the metal blades worked well in the tall grass and blackberries but when I hit the vine maple it broke the head where the pin holds the blade and sent the blade who knows where. Mostly my fault, but it is really more lightweight and intended for grasses and such.
