My BXpanded Backhoe thumb has been just great for moving big rocks, grabbing piles of branches, or even big logs. The problem is I have to get off the tractor to set the position of the thumb and I've gotten tired of doing that so I’m going to convert it to hydraulic operation. This is Part 3 of this project. I encourage you to watch Parts 1 & 2 first if you haven't already:

Hi Martin, Very nice build. I really liked how you took time for the extra details to make this a good working system. There is one item I would have changed is to change from a 3/4" pin on the thumb, upsizing it to 1". Your idea of running the long hoses up to a junction point is an absolutely great idea. So much better like you mentioned if a hose fails, it will be easy to replace on the digging end. Excellent video series. I give you an A+ 😊

Thank you Tom! The grade 8 3/4” bolt has been plenty strong so far when it was a mechanical thumb so I’m betting on it being strong enough for the mechanical thumb, especially with the heavy duty support the spacers and gussets provide. Time will tell. I figured if the Kubota thought it was a good idea to use bulkhead fittings, I should too. Thanks again for the kind words!

You did a good job with the install Martin. I said it before but, I will say it again. You make awesome instructional videos! You really have a knack for them, and the voice. lol Have a great weekend! See ya!

Nice job Martin. Yes if you plumb the valve in end of the circuit you won’t have that drop in your boom cylinder. Also the pressure relief valve you won’t need it . The bucket cylinder doesn’t have enough pressure to hurt the thumb cylinder. I’ve been using mine for two years now I haven’t had one issue with it. Great job Martin ! You will enjoy having it . Cheers

Thanks Sam! Glad to know yours has done well and I won’t need the cross over relief valve. Thanks for watching!

What an outstanding video Martin !! And once again, your attention to detail is impeccable. You've taken quite the daunting project and made it where its understandable to us all my friend. Hydraulics is one of my many weak points but you nailed it !! Your field test shows it to be a potentially great tool for using around the sawmill too. Awesome job !!

Thank you for your enthusiastic encouragement Wendell! This has been a fun project and I got to learn a little bit about hydraulics.

Hi Martin, that's a fantastic addition to your tractor. I think the cross over valve would be a good protection.

Thanks Ross! It sure is a lot more convenient than the manual thumb.

How's she goin'? This is a nice add to your tractor and you did a great job with the install. The issues with the way the 3rd function and crossover pressure relief valves are plumbed in are things that, with use, will present you with the ideal solution!! There is lot of planning and looking ahead when installing a 3rd function eh. Looks like you covered all the bases though. Thanks for sharing Martin and take 'er easy!!

Good evening Mike! Yes, I think it’s a great improvement and will be even better when I replumb it and add the crossover relief valve. Thanks for stopping by!

Might look into using wire loom and cable loom holders to keep away from moving parts. Clean install, well done.

Bonsoir Dave! Merci beaucoup! Yes, I could have made multiple passes with my little welder but I didn’t want to take the chance knowing the enormous stresses those parts will be under. The advice from viewers more knowledgeable than me has been great! And that really was the sound of the zip tie but I couldn’t resist making the joke. 😁 Thanks for watching! Cheers!

Wow, what a fantastic project Martin. I selfishly waited for all three episodes and bing-watched all three tonight! Really impressive stuff. Look forward to the 2.0 episode. Well done! 👍👍

Thanks, Chris! Glad you enjoyed it! I have to figured what fittings and hose lengths I’ll need to re-plumb it and add the crossover relief valve. More fun ahead! Thanks for watching all of them binge style!

The crossover relief valve was a very smart move in my book.

Hi Gary! It will be when I install one, which I’ll cover in the follow-up video at a time that is later than now.

Hay Martin, I would love to do this to my little backhoe.thumb that My company has taken to renting various mini excavators (whatever is available quickly) to do small excavation site work (well work/repairs). Some hydraulic set ups work better than others (thumb gets in the way). definitely a learning curve to each machine...I like that you called it version 1.0. I look forward to seeing the final revision and how much set up vs learning curve it takes. As always great Video!

Hi Bubba! Thumbs are supposed to get in the way - in a good way. Then get out of the way when not needed - ideally, anyway. I’m looking forward to making the changes and wrapping this project up, but it’s usable as is. Thanks for watching!
