Trenching Bucket for a CASE / DAVIS D100 backhoe

[hellspcangel911]

Hi All,
I recently purchased a 1979 Lo Boy / International tractor with a 1050 loader, great little machine. I purchased it from the second owner, the original owner fabricated a full underbody mount to attach a D100. Its severely overbuilt and works well (other than the bucket leaking down and scraping the ground sometimes).
I see a lot of people use these D100 hoes, but I cannot locate a single bucket for them anywhere. Mine came with a 16" bucket and its too big for the little PTO pump to move and I bought the little machine to do some basic trenching around the house. I know originally it was offered with a 9" bucket but I cant find that anywere, and the chinese buckets for sale everywhere dont fit. Has anyone had success finding or modifying a small trenching bucket? or bucket Ears for sale?

thanks
George

George, first of all it's not surprising that your 16" bucket strains the hoe's capability - its condition would equate to a toothless old man trying to eat a stringy steak sandwich...

I know, 'cause that's the condition my 580B's 24"hoe bucket was in when I bought it about 14 years ago. Those "nubs" are about half worn away from what they started out as, and the actual TEETH that're SUPPOSED to be on 'em would NOT stay on if you found some originals and tried to put 'em on.

For that bucket to work as designed, all those shanks (the nubs) would need to be cut off, and replaced with new shanks AND teeth; and digging should be stopped should a tooth come off, til it can be replaced...

As to the trenching bucket, my answer(s) would depend on your welding/fabricating skills - the bucket mounts on the D100 are MUCH simpler than the ones on my 580B, which uses some "S-shaped" ears - your ears appear to be just some relatively heavy flat stock, with both pin holes the same distance between ears

So if you found an "earless" bucket, it shouldn't take much to make it fit (again, that's from MY viewpoint, but I've been "rolling my own" for at least 45 years, and have welders/plasma/acetylene, and tools that'd make a LESS greedy bastard embarassed)

Now, to post this and see if the link worked - Nope - after clicking on the link, scroll down and click the LAST pic - shows the straight mounting ears... Steve

The D100 has been around forever... Started with Davis, went to Case, then I believe Aztec Underground, and they sold it down the line someplace else... They're about the stoutest hoe I've run across in that size range.

Mine is on the back of my Case 646. Over its life it has beat up that tractor to the point it was cracked in several pieces. It has a ton of power for it's size. The Case puts out 8 gpm around 2000 or so psi (perhaps a bit more, I forget). I do all my digging at just above idle, so I'm not getting anywhere near that flow, and don't need the pressure to pull the 16" bucket in clay/rock. I don't know what your pump is putting out, but you might want to check it out.

Yes, you should address the teeth on your bucket. Those shanks are beat, and I doubt they'd take a new tooth, even if you weld them on. New shanks and teeth will make digging easier.

As to your original question on the trenching bucket... I've been looking for one for the last decade. If I found one, I'd buy it for sure. However, a 16" trench isn't really a horrible thing. Sure, you could put a 12" or even make a 9" for it. Then you have a skinny little trench to work in that gives you no extra space for dirt when a wall collapses a little. On top of that, you have already likely torn up the grass on either side of the trench with the outriggers, so you're going to be raking and seeding anyway... I have a 20" for mine as well that I've never mounted. I'm sure the hoe would have no issue pulling that or even the 30" they offered. The problem for me would be the tractor is too light to stay in place, so the 16" is the sweet spot.

One side note on the hoe... Make very sure you never hurt your valve stack. It's a Cessna, and out of production about forever. The end section on mine cracked, for reasons unknown, and I wasn't able to come up with one. New stack valve was painfully expensive, and a pain to install.

That hoe should handle the 16" bucket fine. I had one much like it. A smaller bucket won't help at all, and narrow buckets are a pain in sticky soil. If it still won't dig with new teeth, the problem is elsewhere.
Since you have a PTO pump, my bet is that the filter and the tank strainer on the remote hydraulic tank are both old and stopped up. If not, the PTO pump is worn.

First thing I'd do is clean both filters - if it has two - and then put a hydraulic "T" with a pressure gauge in the line from the PTO pump to the controls to see what you have.
And get some teeth put onto the bucket. Any welding shop can do it.

Everyone -THANK YOU. I appreciate you guys taking the time to respond. The tractor does need a full tune up as its started sputtering out just while raising the front loader- I've got everything ordered and I'll give her a full day at the spa next week. Including hydraulic fluid flush and new filters/screens...
It digs great, I have a full size 310D back hoe with a 24" bucket (and that has trenching buckets available) I just wanted to use this one in tighter spaces and where I dont want to ruin the lawn with a 6 ton machine.
Steve- I've been contemplating buying a small bucket, even one of the TITAN chinese ones for $200-300 and welding it up, I just have enough tasks that if i could avoid another project (as fun as it is)... Also considered cutting the stock bucket down, taking 3" off either side and welding it back together, doing the shanks at the same time.... but again a project...
Thanks for the warning on the Cessna stacks - im starting to get the feeling everything I buy is impossible to get parts for....
