I bought the h12 mini excavator went to Chicago and picked it up and brought it home I also ordered the hydraulic thumb to go with it they told me this was the thumb that I needed to install when I got the thumb in the mail try to put the thumb on the hydraulic fittings on the end we're not the right size to connect to the h12 excavator I had to take it to a hydraulic shop to have it finished also the h12 mini excavator had a lot of loose bolts I had to install two fans one to blow air in and want to pull air out to keep the engine cool

Seems well-built although had a lot of loose bolts when it arrived I do wish tracks had more power and speed but it digs great plenty of power otherwise I think it’s gonna be a great little machine definitely need to add hydraulic cooler and fan
