This Excavator Grass-Cutting Attachment Is Oddly Satisfying to Watch

What's going on

A Japanese construction equipment manufacturer called YUASA Kiko posted a video of their grass-cutting attachment in action — and it hit a nerve. The device mounts onto a mini excavator (called a yunbo in Japanese slang) and tears through dense vegetation with the kind of effortless smoothness that makes your brain go quiet. No speedup, no editing tricks: that's just how fast it moves.

The product is called "でえれぇ刈れるガー YKG-28C" — a name that sounds like gibberish until you know it's Okayama dialect for "This thing cuts a ridiculous amount." The playful branding is very on-brand for Japanese agricultural equipment, which has a long tradition of dad-joke product names. The thread became a mix of people desperately wanting one, people connecting it to landmine clearance tech, and a surprisingly earnest discussion about rural Japan's vegetation management crisis.

Thanks for your hard work everyone 😊 Here’s the video of our “Deeree Kareru Gaa YKG-28C” we introduced yesterday 🎥 And no, the video is NOT sped up! 👀 The 40% weight reduction means it glides through the grass — that smooth operation you’re seeing is real 👏✨

皆様お疲れ様です😊 こちらは、昨日ご紹介した「でえれぇ刈れるガー YKG-28C」の動画です🎥 なんとこちらの動画倍速ではないんです！👀 40％の軽量化により、軽やかに草刈りをすることが可能なため、動画のようにスムーズな草刈作業が行えます👏✨

Thanks for your hard work everyone 😊 We weren’t at CSPI2026 this year, but the YKG Series has a new member — the YKG-28C! 🍑 About 40% lighter than previous models, and it handles not just grass but bamboo too 🎶

皆様お疲れ様です😊 今回、CSPI2026での展示はありませんでしたが、「でえれぇ刈れるガー YKGシリーズ」にも、新たに＂YKG-28C＂が登場しました！🍑 従来品より約40％軽量化されており、軽々と草刈りのみならず、竹を刈ることもできますよ🎶

This gives me the same satisfaction as watching a teeth-cleaning video.

歯石除去動画と同質の快感を覚える

Looks like a giant electric razor.

ひげ剃りシェーバーみたい

Whoever’s operating that excavator is really skilled.

重機の操縦、とてもうまい。

Waaah… I wanna try it…

わぁ…やってみたぁい…

We actually use one of these. ✌

愛用させていただいてます✌

Is this different from the Kusakarugon (another popular Japanese grass-cutting attachment brand) we use every year, or just a different manufacturer’s take on the same thing? It does look smoother — maybe because it’s smaller?

クサカルゴン（毎年お世話になってます）とはまた別の仕様なのかな？　単純にメーカー違い版？確かによりスムーズに感じるが、小さいからかな？

Why do Japanese manufacturers insist on naming their products dad jokes.

なぜ日本メーカーの製品名はおやじギャグなのか。

What’s the “でえれぇ刈れるガー” pun supposed to reference? Only thing I can think of is Eren Yeager. (Attack on Titan character whose surname “Yeager” sounds similar to “Gaa.”)

でえれぇ刈れるガー YKG-28Cって、何とかけてあるの？エレン・イェーガーくらいしか思いつかない。

The product name “でえれぇ刈れるガー” (Deeree Kareru Gaa) is Okayama dialect for “it cuts a ridiculous amount.” The suffix “ガー” (gaa) is a regional sentence-ending particle that sounds like an exclamation. The pun works on multiple levels — the dialect pronunciation, the “Gaa” sound itself, and the implied intensity.

Oh, it’s Okayama dialect — I thought it was Nagoya dialect. I was gonna suggest “Deera Kareru Dekan Waa” for the next model. “Dera” also means “a ton” in Nagoya-speak. (Both Okayama and Nagoya dialects have their own intensifiers that sound similar, leading to the mix-up.)

名古屋弁かと思ったら岡山弁なのか。次世代機には「でぇら刈れるでかんワー」って提案したかったのに。「でら」も物凄くという意味があります。

Thank you for the comment 🙇‍♀️ Wow, Okayama and Nagoya dialects really are similar! I didn’t know “dera” meant the same thing — I learned something new 😊✨

コメントありがとうございます🙇‍♀️ 岡山弁と名古屋弁似ているんですね！「でら」も同じ意味なのですね、勉強になります😊✨

Can it handle bamboo grass? And is there a version that fits on a mini excavator?

笹もいける？ミニユンボで使えるのはある？

@yuasa_ss — Official

Thank you for asking 🙇‍♀️ It can handle things up to the thickness of thin bamboo 😊 This model is compatible with 2–3 ton class excavators ✨

コメントありがとうございます！🙇‍♀️ 細い竹くらいのものなら刈ることが可能です😊 こちらの商品は2～3ｔクラスで使用できます✨

If there was a mini-excavator version with the same power, that thing would sell like crazy.

ミニユンボのサイズで同性能あったら人気出そうだな

@yuasa_ss — Official

Thank you for the comment 🙇‍♀️ This model is designed for 2–3 ton class machines 😊✨

コメントありがとうございます！🙇‍♀️ こちらの製品2～3ｔクラスに対応しております😊✨

This is incredible! I want one.

素晴らしい！これ欲しいわ

It looks so much lighter! We kept worrying our backhoe would tip over when extending the arm to mow — this solves that!!!

本当に軽そう！腕伸ばして作業するとバックホウ倒れそうになってたから、良い！！！

I want one so bad…

いいなー…

Satisfying as hell as long as you’ve confirmed there’s nothing buried in there first.

残置物が無いの確定してるとこでバリバリしたら気持ちいよね

If there’s a version for a small excavator, I am SO in!! I’ve got an abandoned orchard I need to clear!! Mow it, beat it, rip out the roots — if I can just swap attachments on my yunbo I could do this!!

小型掘削のユンボにつけられるアタッチメントなら、やってみたぁーい!! 放棄地になった果樹園の整備にやりたい!! 刈っても殴って抜根して、ユンボでアタッチメント変えるのでいけるならやってみたい!!

With this, at least you don’t have to worry about a bear charging out of the brush while you’re mowing… limited to wherever a machine can fit, though.

コレなら草刈り中に藪から熊が出てきて… なんて心配なさそうですね重機が入れる場所限定だけど

What license do you need to operate this? Is it waived on private land? I want to try.

これ、なんの免許で使えるのかな。私有地なら不要？やってみたい。

@yuasa_ss — Official

Thank you for your interest 🙇‍♀️ Operating the excavator itself does require certification, but please do consider it 😊✨

コメントありがとうございます！🙇‍♀️ 重機の操縦に資格が必要ですが、ぜひご検討くださいませ😊✨

YUASA — the folks behind Faji and Gemkan (other popular YUASA attachment products) — are at it again with another great attachment.

ファジやジェムカンでお世話になったり現在進行系でお世話になってるYUASAさんがまたおもしろアタッチメントを作ってらっしゃる

This looks like it could be derived from landmine clearing tech, no?

地雷処理機の応用ではないですかね？

This is a grass cutter, but the same chain-flail design is actually being used for demining in Ukraine.

これは草刈機ですが、同じような構造の地雷処理機がウクライナで活躍してますね。

Yeah, the kind where chains spin and pound the ground. Anything buried too deep still needs to be done by hand, though.

鎖ブン回して地面に叩き付けるやつですね。ある程度深い所の地雷は手作業しかないかな。

I want to tell every local government: instead of wasting the wildlife damage budget on useless stuff, just buy one of these. It’d cut wildlife incidents by like 30%. Seriously.

鳥獣被害対策の予算無駄遣いするくらいならこっち買えって自治体に言いたい。鳥獣被害30%くらい改善するよ。マジで

Wild lawnmower mode?

ワイルド芝刈り？

Looks about ten times more efficient than doing it by hand.

人力草刈機の十倍効率良さそう

Keeping the overgrowth under control is genuinely important.

藪を放置しない事は大事

Exactly! Clearing the undergrowth really does reduce wildlife encounters. The satoyama (Japan’s traditional semi-wild buffer zones between villages and mountains, historically maintained by residents) used to act as a boundary between human and animal territory — but now that nobody lives there to maintain them, animals just walk straight into town. And there’s no money and nobody left to manage it. Rural agricultural departments are completely overwhelmed.

そう！草刈り柴刈すると野生動物被害減るんよな人と動物の暮らしの境界だった里山に人がおらんくなってもうダイレクトに出会っちゃうからてぇへんなことにでも管理する金もない人もおらん地方自治体農林水産課の仕事が多すぎるんじゃ

My grandpa said “Back in the day there weren’t nearly this many leeches or deer ticks. We used to do controlled burns back then…” (Controlled burning, once common in rural Japan for clearing fields and forests, has declined significantly due to regulations and depopulation.)

👴が「昔はヒルもマダニもこげんおらんかった。野焼きをしとったからな…」って言ってた！

Why not just use this for all roadside maintenance?

道路管理の草刈り全部これでいいじゃん。

Our municipality actually has mowing vehicles, but there’s not enough budget to run them as much as we’d need to keep everything clean… I think that’s the case for most towns ( ; ˘-ω-)

草刈り車両ある市町村だけど稼働させまくって綺麗にし続けるほど予算ないんだよね… そう言う市町村が大半な気がします( ; ˘-ω-)

Honestly that sounds like it should fall under the wildlife damage response team’s job description, no~

それこそ鳥獣被害対策実施隊の仕事では？って感じですねぇ〜

If you completely clear arrow bamboo thickets four years in a row, by the fifth year sprouting is sparse enough that manual cutting can finish the job — and within a few more years it’s gone.

シノヤブは4年連続で丸刈りにすると 5年目の発芽がポツポツになるからあとは人力で刈れば数年で枯れる

My take

I have no plans to use one, and I definitely don't own an excavator — yet somehow I still want it.
