Questions & Answers

Can you buy a strap that this unit has slots for?

Asked by Jhopp December 21, 2020

Answer

I suppose you could but I'm not sure where to get one and straps on weedwackers are somewhat unusual unless you're using it more as a constant use machine or a brush cutter and the machine wont take anything but the cutter head it comes with so the question is perplexing. The unit is light (lighter than a gas model) and if the trimmer shaft handle is adjusted to fit the user correctly a strap isn't neccessary. It's a matter of ergonomics. You want to use the machine with your left hand on the shart handle and right on the throttle grip. Keep your lower back straight to avoid an "ouch", bend the knees slightly, and keep the right arm slightly bent and loose and use your left as pivot point, moving the cutter head up as needed and down by slightly pushing up and down with the right arm. I've been running these things for 30 years and this is how I do it and I have never used a strap. Good luck

How do you remove the head to change to a universal?

Asked by Buzz August 16, 2020

Answers

The cutter head comes off by turning the bump feed knob off as it says in the owners manual. Once it's off the entire head can come off. I'm not sure what you mean by "universal head". Any head that could be used to replace the stock one would have to fit on the splined shaft of the trimmer. If MTD doesn't offers one (Check the manual but I don't recall any heads in mine) then it probably can't be done and shouldn't because it may present a safety issue and damage the trimmer motor.

Can I use the Remington 4.0 battery in this trimmer?

I would think so but check the manual.

can you use the blades instead of string on this product

Asked by ralph May 24, 2020

Answers

Anything other than the stock cutting head will likely not fit the motor shaft and could pose safety issues. So even if it did fit not recommended

Hello, how thick of a line can I use with this weed wacker? Thx!

Asked by maria April 23, 2020

Answers

The recommendation for line is .080 trimmer line. You might use .060 buy it may break often. Anything bigger than.80 will jam the feeder in the cutting head.

Not as good as I was expecting
[This review was collected as part of a promotion.] First time user of a Remington 40 Volt Lithium-Ion Cordless Electronic Trimmer 2.5 battery and right away noticed how hard it was holding the two buttons the entire time cutting. It should not be this difficult to cut the grass. The string also kept tearing off a lot more then other brands I have used. Then I would have to pull out more string and it has to be exact and if not it makes this loud grinding noise until this metal guard underneath cuts it to the perfect length until yet again you need to release more string. s The string also kept tearing off a lot more then other brands I have used. Then I would have to pull out more string and it has to be exact and if not it makes this loud grinding noise until this metal guard underneath cuts it to the perfect length until yet again you need to release more string. Grass also kept getting stuck around the spool and would have to stop and clean out the grass along with the blade stopping from being jammed up. Using this cutter took longer to trim my yard then i expected and I would not recommend this cutter to anyone, I was extremely disappointed in the quality. Before receiving this product for Free I was not aware of this trimmer and I would not recommend it after having such a bad experience with it.

Edges and trims as well as a gas unit.
[This review was collected as part of a promotion.] I used this trimmer for the first time this weekend. I was impressed with the features and power. It is lightweight and well balanced not feeling heavy on either end.It worked as well or better than basic gas units with out the hassle of gas/oil and praying they will start. The telescoping shaft makes it compact to store and the rotating head easily switches between edging and trimming. I did struggle some with the "Bump to feed" line. But I never found even the commercial units that work well. Battery life is good. I would recommend reading the directions!
by Rainman
I would buy this product again
[This review was collected as part of a promotion.] My husband used this in our yard we actually have 2 yards we have to mow and weedeat and he did both in about 45mins the battery charged quickly and kept the charge the whole time he was working. One of the things that we really like is that we can extended it for him and shorten for myself and it can also be used as a edger. The only thing we didn't like was the button you press to use it it made his hand red and made it cramp up but we would buy this product and recommend it to others

Love this line
[This review was collected as part of a promotion.] This trimmer is so much better than other electric trimmers I have used in the past. I'm very happy that it is cordless and that the battery lasts for a very long time. I was not aware of this product before sampling, but am thrilled that I was selected because I love it and plan to buy other products from this line. I would HIGHLY recommend this product to others.

Trimmer that will out last you
[This review was collected as part of a promotion.] I love this Remington trimmer because for starters it's adjustable all the way around. It has a very nice grip and the battery life is amazing. It does get tiring after about 20 min of holding it because it's variable speed, so don't forget to take breaks. The harder you hold it the faster it goes. It cuts really good since it's cutting from two sides. The pivoting head makes it easier to trim hedges by turning 90 degree angles. All in all I'd say this is the best way to go for any size yard. It's very durable and sturdy. Lightweight without battery which evens the weight of the trimmer.

I am impressed with this Remington cordless trimmer. It is well balanced after adjusting the handle to my optimum position. It ie equivalent to your gas powered unit in size. It comes complete with battery and charger, larger battery optional. The head also rotates to become an edger, making trimming sidewalks a breeze. It comes with heavy duty trimmer string already loaded. Packaging for shipping was great, no chance of damage.

Overall I thought the trimmer worked just okay, the head rotates from a trimmer to an edger easier than my other trimmer, but it took a while to figure it out, I did not read the manual I just read the drawings on the label This trimmer lost two stars from me due to the fact that the bumper head jammed frequently and I could not advance the line properly. Even though I had difficulty with it, I would still recommend it because it has great features and was fairly lightweight, thus reducing fatigue I have another trimmer and the bump feed works fine , this one gave me a lot of difficulty. It took about 30minutes for me to figure out how to change the head from trimming to edging. There are 2 arrows on the label on the head but I thought it was showing me how to change the angle since it is in the same area. To adjust it you have to first pull up and then twist it. - This trimmer runs pretty quietly to me. The DB level of the area I was in was 45dbs prior to using the trimmer, while using it my sound meter gauged it at 78dbs, that was the loudest it got up to while cutting the grass, but the sound level fluctuated between 70-78dbs -This trimmer felt light but not flimsy so I did not have to worry about fatigue. The charge time was about 90 minutes out of the box. The value of this trimmer kit is high due to the fact that Remington makes plenty of other outdoor equipment so you have plenty of products to use with the battery.

This is a higher end cordless trimmer which is immediately noticeable right out of the box. Unit includes a nice set up the the swivel head for ease of doing things like sidewalk edging. Battery is easy to slide into unit and has a pretty good balance. The extendable shaft feature is adjustable for varying height of user. It did not come with a shoulder strap which is badly needed to hold the noticible weight of the tool for an extended period. Medium duty unit for residential application that does a nice job cutting with good power. Hopeful the battery will last all season, have yet to find a cordless that does.

This is nice trimmer for home use. I found it easy to use and at an average weight for cordless trimmers. It has a nice adjustable trimmer head that allows you to swivel it to different angles as well as twist the head. This allows for easier edging use of the machine. The length also extends so that people of different heights can use it more comfortably. I am taller so I extended it to the max which was nice but did make it feel a little unbalanced. Overall cuts very nicely with good power. Great for an average homeowner but may not be strong enough for heavy usage.
