My New Ripper tooth

[jcav44]

I've been lurking around this forum for months now and this is my first post.
Since I seen the ripper tooth I knew I had to build one for myself. I thought
I'd share some pictures with you. I did most of the work at my job in my spare
time and I didn't take pictures of the build so these are pic's of the finished
tooth. The body of the tooth is made up of 6 pieces of 1/4"plate steel welded
together, the tip is a Hensley T23L $11.00 at Groff Tractor mounted upside down.
The body is made up of 3/8"x 6" flat and a 2 1/2"x2 1/2"x 5/16" for a center brace.

Nice job. What are you planning on tackling with this? (I am guessing tree roots????). I have seen them traditionally used with frozen ground.

How long does it take you to swap out the bucket for the "Hook"?

Same here...

Did a tree stump this afternoon took about 10 minutes it's the first time I used the tractor.
I live in central Pa. it's loaded with shale and clay and when it's dry it's like concrete I'm
Thinking the tooth will come in handy when I run into that. As for swapping out the bucket
for the tooth I never actually did that I'm thinking 5-10 minutes

I would like to see before and after shots of the stump. Also how big was it?
Your tooth looks similar to the one I had built. I tried it out a few weeks ago and wasn't all that impressed. Then again I'm attempting to remove 16" plus stumps, in the woods. So I'm having to deal with much more than just the stump roots of what I'm trying to remove.
It takes me over 30 minutes to change from ripper to bucket. But the again 85#'s is pretty much at my weight limit. I'm thinking of making some frames so I can keep in position and roll it around.

I does look a like a nice ripper though. Keep us up to date the destruction you do with it.

Would cutting some "V's" in the hook part help "saw" through the roots (like a serrated edge)? It seems to me that if you hook a good size root, all you are doing is creating a real good anchor! I am just wondering if some teeth would allow you to rip and tear the roots

I put a tape on that stump it was 10 inches across, it was also
a jack pine with a shallow root system. As for changing out the
bucket I haven't done it yet, I took the bucket off to build the
tooth and haven't put it back on yet. I know it didn't take more
then 3 minutes to put the tooth on, I just put it on my shoulder lifted
it up and put the front pin in, after that I just swung it back and
inserted the rear pin.

I understand if you can't lift the tooth and have to use the hydraulics
to mount the pins it could take some time. Maybe some day I'll look
at building a quick change for a a small backhoe Attachments for your construction equipment including: excavator buckets, backhoe buckets, Wain-Roy buckets, Wain-Roy quick changes, loader buckets, winches, arches, fair leads, fairlead, grapples, log forks, backhoe attachments, compactors, hammers, brush rakes, blades, rippers, pad-foot or padfoot roller kits, and more.

As for the performance of the tooth. Using a my 16 bucket I'm spreading
the force of the backhoe over a surface area of 4 teeth, with the ripper
tooth I concentrate that same force on 1 tooth. I see this as the most power
I'm going to get out of this small backhoe. If it takes 30 minutes to dig up a 16
stump then so be it, just think of how long it would take you with your bucket.
also with the ripper tooth you have a smaller foot print when you're done

I had thought of doing that when I was building it but I got tired of welding
So I called it quits. Now that I used it I don't know if it would help much.
I've only operated this machine for a very short time but I found all the power
is in the bucket curl and very little in the boom and dipper so sawing in an up
and down motion might not work out so well. I put the tooth in the ground
and curled in till I hit a root then I came up and started to take the root out a little at
a time. I did this all the way around the stump till it came loose.

Sorry I have no before pictures

I see your point ... Maybe since you have the mount, make a thumb / shear so when you curl, it cuts the root!

I know .... Easier said than done. Either way, nice job

This is the one i had made . The lower tooth is for breaking the lateral roots off . While it is doing that it vibrates the stump and helps loosen the soil around the tap root . The top teeth are for pulling and pushing the stump to loosen even more before reaching over and under it and lifting free .

It looks cool, but how would you rate it's performance? Do you think you are getting the desired result because of the machines capacity, or because of a better design? Both of your guys hooks look like they would work great for demo work, but they seem to rely more on brute strength than cutting or tearing action.

I only say this because my machine has much less oomf (thats a technical term by the way) and I am looking for a way to overcome it's lack of power.

I used to use full size BH loaders to dig pits but when the ground froze to more than a couple of feet, it was like digging in concrete. I was always amazed that the larger excavators could still work, but there was no comparison in HP.

That said, you guys did a nice job .... there is just something about a good "hook"!

 

[wedge40]

Paul I have agree. I think Iron Horse's look like it would take a pretty stout backhoe to work.

I'm in the same boat as you and use the bucket curl to me work. what I have found though is with the tooth as you apply force with curl instead of it applying force on the root most of that force causes the tooth to sink in the soil along th back side. (does this make sense?) I was wondering if you put a plate about 6 or 8 inches wide along the backside if this would give more leverage?

I have used the tooth at the end to chip at some bigger roots. Not very productive.. I'm waiting till have the time to spend more time in the seat. I'm traveling the next 4 or 6 weeks and will only have weekends to play/work.

bx24// I love it when you post , the smile on that little girls face melts me . I think my ripper is better than a standard curved one in the sense that it will catch on the stump and not slide around it . As wedge40 has found , the slippery root and the curvature of the tyne forces the crowd ram back and blows the relief valve as you loose purchase when the root gets to the bottom of the tyne or as you curl in the tyne rolls under the root . If it's a matter of "oomf" it's a simple matter to down size the tearing tooth . My machine can break a 3" root so thats what i based the size on . If i strike say a 6" root it tears off a 3" chunk and gets the rest on the second bite . If your hoe can only break a 1 1/2" root make the tooth that size , it will then do a 3" root in the same fashion that mine does a 6" . The secret is to keep the root high on the tyne where your purchase is greatest , that's what the hook does . You could try sharpening the hook but i think by the way the stumps twist whilst im tearing at them it realy does help to loosen them , rather than quietly slicing the roots and still having the tap root firmly planted . Once you have have found it is still tight in the ground and you have sliced off all your hold points what would you do then ?

 

[jcav44]

I think I need a little more time behind the controls before I make any more comments. If I find I need some kind of tooth in the hook I'll cut a quarter moon shape from some half inch stock, bandsaw some teeth on it and weld it in place.

Thanks for the nice comment about Samantha ... its amazing to think someone as nice as her came from a putz like me! .... The good parts obviously came from the other half of the gene sample.

I did not think about the greater leverage you would get from a "closer" bite and that makes sense to me.

Can you fault a guy for wanting to put some teeth on things!

 

[EnviroEd]

That sure looks like it'd be fun to play with, wish I had a backhoe. I've been thinking about one of those rippers for my 3ph to help roll big buried rocks out.

 

[Redbug]

Hey EnviroEd...Why not get a subsoiler? Drop it down, snag whatever it is, slowly drive forward while raising the lift arms. Works pretty good for small stumps. Just do it slowly...

 

[EnviroEd]

Redbug, that's what I was thinking about I'm kinda worried about the rock getting stuck between the sub-soiler and the tractor, have you had any problems like that? If I could extend it back farther from the tires I sure would feel better. Thanks for the help!

 

[RonMar]

The problem with extending it back is that you loose lift force on the 3PH with longer lift arms...

 

[Redbug]

EnviroEd, I'm not quite sure about the problem of getting a rock stuck between the subsoiler and tractor. On a stump that is stuck, I go slowly and feel my way with the tractor and back off when the tires begin to spin. I do things slowly to avoid bending or breaking something on the tractor. If you approch the stump from another direction sometimes you can get it to move. I guess a rock can be like that, although I have never tried.
