剪草机刀片原来要这样磨 how to sharp your lawn mower blade 

不磨剪草以后草尖容易黄

我了解下

如果是这么大的地，半英亩以上的，不用纠结了，绝对是汽油机，我推荐Honda的剪草机，或者至少是Honda的发动机。汽油机非常耐用，15-20年以上的寿命。要配备专用的汽油桶，密封好放在车库或花园储物房，不会有安全隐患。保养就是每年换一次油就可以了，不用滤芯。行，我会考虑出一期视频，专门讲剪草。

ZU DIY 感谢🙏 期待视频

专业的油桶也介绍一下吧。去哪装油。运输安全。

I think any power tool has to be used very carefully. Grinder to me is the best tool because it’s so versatile, I almost use it in every project. With different discs, it can grind and cut metals , wood, concrete. To me if you use it handle metals or concrete, I don’t think it is very dangerous, because the disc is not that sharp, powerful but not sharp. Only thing if you use to cut wood, be extra careful, because wood blade is sharp. Always wear goggles and gloves of course.

@@ZUDIY Thanks, I have seen quite a lot of your youtube video, and I saw you using the grinder to polish wood surface, in that case, I guess it should not be that dangerous since the grind disc used should be blunt. right? But haven't seen you use the grinder cutting wood though, also what is the scenario to use grinder to cut wood if you have various saws available?

Chaoliang7 Lin The wood cutting disc is different, people use it to cultivate wood sculpture. I have one but barely used. The disc I use to grinding is flap disc, just like sanding paper with different grits to choose from. Actually it’s best use is grinding metal, you can use it to sharpen knives and mower’s blade. Flap disc is not dangerous, very user friendly. For wood, flap disc do the job, it is faster then sanding paper, but because of high speed of grinder, it also generate more heat, which might burn the surface of the wood. Usually after using flap disc, I will use sanding paper for more smooth result.

可以倒掉，主要是要把化油器里面的汽油烧掉，所以还要发动一下，直到发动机停止，就可以储藏了。

@@ZUDIY 谢谢你的回复，今天我检查了一下润滑油很黑了，是不是也要把它放掉？如果要放掉，现在要不要重新倒入新的？

@@gaopanxu5468 机油不用倒掉，放机子里没问题。你记着明年开春换一下机油再启动就行了。

我片子下面的介绍里有amazon的链接，打开就可以找到，Bosh的打磨机加金属打磨碟，用flap disc来打磨也可以。谢谢！

ZU DIY 我只需要机器的英文名称，可以打几个字吗？不需要品牌名称bosh

Angle Grinder， 碟片： Metal Grinder Disc

還是有區別的，如果刀片太鈍，割完草，草尖會變黃。

Socket wrench sets

@@ZUDIY 请问我看到亚马逊有不同价格的socket wrench sets,随便买一款都可以用，还是一定要哪种size的？

树没问题，但要及时清理落叶，要配备一个吹落叶的机子，Leaf blower。
