[@tylerolejnicak5481]

@@microman502 Everyone here is wrong and it's hilarious. Straight from Wikipedia: "In the field of psychology, the Dunning-Kruger effect is a cognitive bias in which people with low ability at a task overestimate their ability. It is related to the cognitive bias of illusory superiority and comes from the inability of people to recognize their lack of ability. Without the self-awareness of metacognition, people cannot objectively evaluate their competence or incompetence.[1]"

[@BigBear--]

One main problem I see is the tension put on the blade of grass. In the “field” the blade is sorta just hanging there freely, I think it messed with the dynamics of the cut by putting the blade of grass under tension…and we’d see very different behavior if only one end was held in place and the other allowed to dangle freely.

[@BlueChickenFarm]

This!!! I would have liked the clip mounted below holding a piece of grass upright

[@BigBear--]

@@BlueChickenFarm btw, I've settled on that either the Husqvarna Titanium, or the Husqvarna XP+ Line as the best trimmer line. That stuff is strong, flexible, and cuts clean. Most pros that care use either the stuff I listed, or the Echo Black Diamond.

[@xzantronos]

@@BigBear-- echo crossfire line, husky titanium line imo are probably the 2 most durable weed eater lines on the market. I have never been much focused on shape of the line but durability of it and tracking capability unlike that sharp, sharp square that was all over the place.

[@ADBBuild]

THIS! Easy way to think about it is cutting a piece of rope with a knife. Unless you have an incredibly sharp knife, you aren't going to cut through a piece of rope hanging in mid air as it will just be pushed away. It has to be held under tension for the knife to cut through. Inversely, by hold the grass blade tight, you are making it easier to cut and distorting how it cuts.

[@BigBear--]

@@ADBBuild Over a year later my bottom line is when it comes to trimmer line - get yourself either the Husqvarna Titanium, or XP+, or get the Echo Black Diamond. I personally prefer the Husky line. That stuff is super tough, tracks straight, and cuts clean. Also a small recommendation is soak the line for about 24hrs in some water...cause a lot of the time you never know how old it is, or how it was stored or transported. Soaking it in water sorta re-hydrates it, and prevents it from getting brittle. You can also do that to bring it back to life, if it goes stiff on you from dry storage every season.

[@heydeereman1040]

Been using that "Titanium" line for years. Does not cut as cleanly, but lasts significantly longer on properties with chain link and retaining wall stones

[@Madgythumtas]

Possibility of using titanium to do the heavy lifting and then trim up with another?

[@heydeereman1040]

@Madgythumtas yes if I was working a weekly property which had very little chain link or stone edge then I would use thinner X shaped line.

I should say middle. No one really gets to the far end lol

[@ryurc3033]

You have to know something to realize you know nothing.

[@Aim54Delta]

Dunning-Krueger is poorly understood. The study, and subsequent efforts, have demonstrated that people tend to presume they are average in performance regardless of how their performance ranks in absolute terms. If I were to take 100 people sampled at random and have them run, say, 3 miles, we would see them string out, with a few running far ahead and a few practically walking from the beginning. Most will be relatively close to each other or even herd together. Run them all individually to see how they perform, and you will break up the herding but not the statistical clustering of scores. Most people see themselves as "part of the pack" - be they at the rear of the pack or the front. Only when you have them perform as independent individuals can you properly assess their individual capabilities - the fast will not slow down to lead the pack, for example, and the slow will pick up their pace to not lag behind. Our perception of our individual capabilities is seen through this lens. People naturally perceive their performance as existing relative to this pack cluster with those tat the front not understanding how easy/naturally they dominate and those at the back not understanding how hard they have to try to keep up relative to others. Thus, people at the back think they are closer to the middle than they truly are while people at the front do not understand their own superiority.

[@RonJordanpopcornRon]

So glad to know that years ago when the new lines came to life, my take is the same. Star and gater line is the best over all. The 4 edge (squared) like Robert mentioned how it will do for roughs and can cut through tough grasses is not a go to for manicured lawns. It wants to climb down into the grass and get away from you before you know it and then you have a bad spot that is there for the customer to see. All in All a round weed eater line will give you a smooth cut like butter in grasses such as Bermuda & Zoysia grass. In doing so it kind of rolls over the top of the grass while you are cutting without digging lower than what you want to go. And in working throughout the years you learn to slow down your weed eater throttle with your smaller line along your fence so you don't go through it in the first 20 feet.

My weedwacker string does this thing where it melts from friction inside the spool while I am using it. Then I have to shut it off and take the spool apart to get the string out. It’s very frustrating and time consuming! Then I went over to my dads house and used his string trimmer and it was so wierd because it seemed like the string lasted forever! Mine is gas and his is battery powered. Feels like the rpm’s of my dad’s trimmer is much lower,but it works SO much better! There’s a lot of angles to consider when thinking about what makes a string trimmer work well ( or in my case not so well).. Thanks for this video!!

It's about maximizing shear force at the contact point. The star shape does it the best. But with thicker diameter material, the square has a better chance of avoiding the flat contact scenario.

But then wouldn't the round shape be better since a circular shape has an infinite number of edges?

Great video. Understand applying consistent tension to blade of grass for experimental control but now can’t help wonder how much “lift” or negative pressure generation might contribute to a good clean cut.

Because of a future Honda recall, my HRX217 has been in the shop for months, and I had to cut my entire lawn with my weed eater. I noticed that the cheaper more economical lines damaged the ends/tips of my grass so badly, an hour after cutting, my yard looked brown and dead. I tried different lines, to try to get a cleaner and healthier cut - So my yard would look green and healthy an hour after cutting.

Based on the reviews of others I now only use Rotary brand Black Vortex Line Trimmer Line in size .095 on a Shindaiwa gas trimmer (owned by Echo since 08) and Milwaukee. It comes in all the sizes. The one roll lasts me as a homeowner averaging an hour a week a very long time. Even if I abuse it in thick grass or thick weeds/brush it does very well. IMO the shaped stuff tends to bind up and fuse together in the trimmer head, causing you to stop and rewind. Which means more hassle and lost time. The cheap stuff is just brittle and some of the special blades and heads just bog the weed eater down.

I thought that might be the case as well, however in one of the later shots I think it was with the sharp square the line cut a free hanging portion after the bottom was cut free and the cut looked very similar. I think the action is so fast that the inertia of the grass blade dominates that part of the physics.

[@Nozerone]

Most of the time if the belt is vibrating, it's simply because it's not tight enough. I never twist the straps, and the only loads I ever get any vibration in are loads that can compress over time. I have been told that on some loads though (mainly wood), you don't want the twist cause it can cause friction and possible problems. Not sure how true that is, so don't quote me on that.

[@52Ford]

@@Nozerone I twist my straps. The best example I can think of 'off-hand' is hauling some furniture on a flatbed trailer a few years ago. I had to get out on the side of the road and twist my straps because it was literally starting to friction burn the fabric where the straps were fluttering. If I'm concerned with surface damage, I twist. Otherwise, I don't care. It's probably better to twist, as you're putting less wear on your tie-downs by not making them flutter.

[@lithiumdarko2113]

Just so you know the off balance of the sharp sharp square as you call it is best for long grass because it helps mulch the grass down and leave less of a rake up to worry about and i like the star one because it gives a clean cut but also best for certain types of grass the short type of grass you want to give a clean cut or clean top off for example the spongy grass as i will call it for those who don't know their names so its all about looking at the lawns you work with if its always long and messy or short and just want a small touch up
