I just bought me a mini Chinese excavator last week. I've been really appreciating your videos. People have to manage their expectations with these machines. I bought mine to replace a shovel not to replace a 2-speed kubota.

What an absolutely fascinating video. Even if I had not been interested in the topic, I would have found this content absolutely riveting. The content is perfectly paced and very, very informative...

Your videos are showing up on all of the Chinese mini excavator sites now. Great job! Keep growing!

I can walk faster than this thing moves. It's ridiculous! I've contemplated putting the mini excavator on a little trailer just to move it around at the work site. Thanks for your research with this issue. Very helpful, Thanks!!

Great information...I made my own machine....also got annoyed it went so slow....I had 2 single acting spool valves left over from another project..I plumbed these up to switch the drives from parrellel to series....get double the speed,just can't turn,but don't care as I'm just moving from one place to another...thanks for the great channel.

The coupler between engine and pump is not really for damping vibration but more to compensate angular and radial misalignments

Very informative, thanks for taking the time to put this together. Looking to pick up one of these machines in the near future.

You are an awesome teacher! Subscribed!

Keep this stuff up, love it.

Thanks for highlighting the importance of filtering and cooling hydraulic fluid!

Great video! probably the best one I've seen on the topic of mini chinese excavators. Bravo!

Your video is awesome. I just picked up a H12, and have learned so much from you. Definitely interested in any upgrade packages you come up with.

Dude, love your videos on these. Mine was just delivered and this is so helpful. I’ve used a lot of the big name brand mini excavators and they are all slow. When you’re in a tight area, as these often are, you don’t want a super fast, twitchy machine.

very educational video!

great video Cam, appreciate the time and thoroughness. looking forward to more.

Just what I needed. I am new to this (bought a Chinese 2.5t), and love this excellent explanation, more explaining the "why", or here "why not". Thanks you!

I'm really enjoying watching you take your machine apart so I dont have to 😂 I mean, i know i will eventually, but this insider knowledge is extremely valuable. I'm currently waiting on a call from a guy, hopefully I'll be owning one before the end of the week.

I am working on fitting a hydraulic filter into the mix right now. And have designed a quick attach with tilting head too.

I'm building a skidsteer and I've seen a lot of very informative videos to guide my design. But I have to say this video video definitely shed a lot more light on my direction. Thank you for this!

Great video. I also own an H12 and you are spot on with your engineering analysis. Please look into the overdrive issues with the track motors. The digger will accelerate past full speed when transitioning onto a slope with enough slope, giving the operator an “oh, crap” moment. Pulling back the track controls fully will throttle back the track motors. I believe there is a mod to correct this. Please comment.
