Thumb Ideal Thumb size

I just recently bought the BXpanded Barracuda Factory Fit Thumb for my BH77 backhoe. It is specifically designed for my backhoe. I chose it over a Kubota OEM thumb for three reasons:

1. The BXpanded thumb costs less.
2. I felt the BXpanded design with the curved jaw was better.
3. This one is the "long jaw" version which was specifically designed to work properly with my BXpanded quick-on bucket connect so that the thumb meshes properly with the bucket edge and teeth. There is a shorter version for folks without the quick-on bucket connect.

Attached is a picture of the thumb and how it meshes with my 16" bucket and BXpanded Quick-on Bucket Connect, which makes switching to my trencher bucket or ripper tooth really quick and easy.

Here is a video of me installing, and testing the thumb for anyone interested:

This thumb fits the BH65, BH70, BH76, and BH77 Kubota backhoes. You'll see in the video why I highly recommend it.

Looks to me like that thumb is a bit too short.

This is the bolt on thumb on the Woods 650 they made for Kubota (B/L4520B) It's a perfect fit.
