Ambitious project. A thumb will certainly spoil you. Once you try one you’ll appreciate the added benefits.

The Kubota M59 thumb pedal was awkward for me. Modified the foot pedal grip and added a hand control option now fits me better.
Indeed, I have wanted a thumb the first time I saw one. I will be fabricating one as soon as this retrofit is done.

I thought about attaching the pedal pad with a U-bolt so adjustments can be made. Then welding after a comfortable position is determined.

Needing to stretch the tie rods to somewhere close to the desired point and not having access to my torque wrench, I came up with this. I think I was able to get as close as most click or dial wrenches would have.

I’m having trouble adding picture. I think I have the picture now.

Like my thumb a lot, as it will aid in moving logs, brush, and can hold material on pallets when teetering on the forks.

I have not been happy with my thumb lately. It

has been painful for over a year now. It started when I ate more than my share of yogurt.

I was looking for a way to manipulate the backhoe to facilitate installing the valve assembly. I discovered what may be the purpose of the heavy slots that are welded to the underside. What do you think fellows, fork pockets?

There was no way the loader was to pick up the backhoe without ballast on the rear, I promptly gave up. I decided to use the loader in a different capacity. It was now much easier dropping the valve/hose assembly down rather than lifting it up into position.

Tie down points.
Gosh, I thought so too when I first saw it. Anchor points are typically loaded in tension. This piece would be loaded with a high bending moment, not good. Also, too many sharp edges to safely attach anything. I actually passed on using this point for anchoring on the two occasions I loaded this tractor on a trailer.

It is made from 3/4” steel and has a fair amount of trimming and welding, not what I would call a cheap piece to make. They look exactly like fork pockets to me but why? I don’t see the point in having fork pockets, curious.

Well look at that! I thought you were showing a typical grapple until I took a closer look. I have not seen a thumb for a loader until now.

Well, this job is ongoing as I gather the final pieces to secure the hoses and make the new pedal control as time allows.

Here I am showing how the hard line is repositioned to accommodate the space taken by the new valve. You can see the needle nose pliers pointing to a bolt head on the floor. Below it is the hard line bracket with two vertical slots. The bracket is simply moved over to the next slot when being installed, no drilling required.
