      The problem you have with the hydraulic thumb not being powerful. The circuit reliefs for the auxiliary spill are probably set too low. They are supposed to be set lower than the bucket circuit pressure because the bucket cylinder puts out so much force that it will bend or break the thumb cylinder rod. But if you tighten up the reliefs to around 2000 psi it should hold anything you need but still release before thumb cylinder damage

        Never seen an excavator with thumb in real life, but the seem to be quite popular in the usa.

          @Andrew Camarata Well in the last 5 to ten Years almost every new excavator has Oil Quick, so a so called "Sorting Grab" can be attached in a few seconds. Before we used clamshell grabs or so called "Rock laying buckets" that are buckets with a very long lip, that also make it easy to pick up rocks or so.

          How are you guys moving stumps, logs and boulders without thumbs?

            @Andrew Camarata Hey Andrew! Really enjoying your vids. I’m construction too so I’m accustomed to doing what you do. Always like a new set of eyes on similar jobs. Sorry bout the wife comment. I saw a young woman clearing an island with you. My bad. Keep up the good job!

          You've got ALL the ingredients, Andrew!! I am now going to make spaghetti sauce. I'll bet you have a killer recipe. No, let's not turn this into a cooking channel. Love your work and inspiration and insight. You are (almost) always right. We think alike. Building, repairing and running stuff is so rewarding.

            IMHO I think you should replace the word "Manual" (thumb) with "Fixed".

                Andrew run the lines. We run 4000 psi hoses and aircraft Adel dumps all the time on hoppers. After watching your videos, you could do it with your eyes close.

                      I discovered this guy about a month or something ago, and one of the first things I payed attention was the thumb on a excavator. I might never have seen that before. Not that I am a huge knowitall in construction, but I do something and have drove some machines. The thumbs just are not so big thing in Europe I guess? Or I just don´t know anything. But if it isn´t I can´t understand why! Those things look soooo handy especially in Andrews mighty hands off course. Anyway, I am very, very thankful for this excellent video. Month ago I knew nothing about thumbs, now I know. I do not own excavator, but I have couple old backhoes. Even thou Andrew did not recommend it I just might ad a thumb on the other. Because I DO move rocks, logs and stumps with it, even when I admit it´s nothing like excavator, but it´s hell of a lot easier with it than without it! It´s all relative :)

                        Even tho I will never use any of the information you gave on thumbs, I understood perfectly everything you taught and found it extremely interesting. Too bad I can't impress anyone with my new found knowledge.

                          Andrew thank you for the videos, I wanted to ask if I should get a mechanical or hydro thumb on my mini excavator. It's a Kubota 1.6 ton but it is piped for a thumb. There are a couple companies that sell a hydro thumb for my machine, and tons that sell mechanical. Which would you do? The cost difference is not very much, 500 to 1000, and the weight is not much of a difference either.

                                What a terrible design on that backhoe. You would think they would notice that you can literally pick the front up by hand during the R&D phase. Lol

                                  ? Does anyone know which excavator he would start out with if he had a choice? New to channel... what do you guys think would be the best bang for the buck?! Thanks!!

                                    Andrew, Isnt the hydraulic thumb easily moved in because of the hydraulic relief valve. Check that circuit i bet the valve is bad or weak. Thank you Andrew for your awesome videos.

                                                      Install the thumb, measure how long it needs to be closed, measure how long it needs to be open.

Not like reporting to a site every day to operate somebody else's junk you have no control over. Great idea to use the pivot circuit to run a thumb but if you don't need it you can save the hydraulics for something else that might be more useful in the future.
