Ripper Tooth for the Backhoe

[threepiece]

I simply couldn’t get myself to spend $1,000 so off to the shop I went. Here the tooth is about 90% complete. I have yet to install the tip but I need to check clearance to the stick of the backhoe 150 miles away.

This is for my JD 110 TLB.

After making templates from cardboard I went to cutting a kit. I did buy a replaceable tooth tip shown on the left.

The tooth is made from 3/4” Hot Rolled trimmed on the band saw.

The hub is made from 4x8x 1/2” wall tube.

Here I am milling a slot for the tooth to pass through.

Here I am preparing to drill the corners of the trim for the quick coupler ears. The template has all the information needed. I can use this template in the future.

Cutting with a hole saw. Notice the two drain holes I cut. This prevents chips from loading up in the cut and allows uninterrupted cutting. Much faster this way.

Finishing the hole to size with a boring bar.

Showing how the tooth passes through the hub to be plug welded on the end.

The tooth is welded inside and outside the hub.

Today I will be fitting the tip on the tooth as I am here with my tractor. I plan to show how that goes later.

Very Nice Work!! Pretty clear from this thread why Ripper Attachments cost $1000!!

Very nice fabrication! Good skills.

Added tabs to the back so ripper would stand upright for attaching. Also attachment points for rigging.

To keep perspective, the commercially available pieces are not cut on a band saw whose trim lines were transferred from carefully prepared templates. Developing the templates and trimming on the saw were by far the most time consuming portions of this project.

I have been thinking about creating a stand for this reason. Having a stand-up feature on the tooth itself allows it to be used anywhere on the job sight, I hadn’t thought of that. I just need to study your pictures as I am having trouble understanding how it works.

Well I wasn’t able to fit the tip as I have clearance issues getting the tooth installed on the quick coupler. Luckily I only tack welded the ears on. They need to move upward 1/2”.

Hope the pictures help.

Couldn’t find a ripper to fit a Kubota B26 backhoe. Bought quick attach ears from dealer. Instead of making a dedicated ripper, made an adapter to allow the use of the KX mini-X attachments liked used on the Kubota M59 and current ripper. KX excavator buckets and attachments much cheaper and easier to find used.

I bought a ripper tooth from Rhinox that is made for a KX121-3, I had my welder modify it for my BH92.

The OP has far better fabrication skills and equipment than I. We both want the end results. Ripper is a game changer for smaller backhoes. One-off fabrication is tuff and time consuming. Welding ears on is a challenge for me. If an old, shaky, achy, diabetic, retired engineer can do it, most anyone can.
