Hi guys,

I saw this ad on CL and the backhoe looked familiar.
http://nh.craigslist.org/grd/2152081636.html

My brother has our grandfather's 646LBH and the backhoe looks identical to the one in the ad. Were the D100's used for other applications? I have never seen one on anything but Grampa's old tractor before.

I have been trying to aquire the 646, but my brother won't budge. (And I don't blame him.)

I believe that the D100 backhoe was originally made by Davis. Davis was a company that made among other things trenchers. Some of the trenchers came with the D100 hoe. Case bought Davis primarily for the trenchers and backhoes. This is all based on memory so don't quote me.. Gregg

The D-100 and D-130 backhoes were actually designed and manufactured by a company called Davis who's main specialty was chain trenching equipment. Creating narrow trenches with an oversize chainsaw was a fast way to get the job done if there were no underground services (sewer,water, hydro, cable, telephone) to get in your way. However, there were also natural obstructions to slow you down such as rocks and tree roots.

That's where the backhoes came in and Davis trenching machines were often sold with one of those hoes on the end of the machine opposite the trencher. Then along came Tenneco/Case and bought Davis lock, stock and toilets because they wanted to add a quality line of trenchers to their ever-growing line of construction equipment. CAT has done the exact same thing.

When Case got into the skid steer loader biz, the D-100 and D-130 hoes were a perfect size for these machines. The added some bolt-on mounting brackets in a spot that did not interfere with the loader. The operator drove up to the hoe with the loader in the air, hooked up the two hydraulic hoses to quik-tach couplers and then mounted the hoe to the skid steer by using the hoes hydraulics to position it. There was a hydraulic stabilizer kit for the rear of the skid steer to make the tractor stick to the ground better.and to level it up.

I'm sure that Case found other applications for them and they may have sold them to other companies that needed a hoe for their tractor. I stared at those crappy photos for some time and I'm not sure just what that crawler is. I have a feeling that it's a 350, which is the smallest track machine that I'm aware Case made. As for the hoe, that did not come new with the crawler because the paint is Desert Sunset. I don't think that it's a 100. If anything, it would be the slightly large 130 hoe.

Oh, one more thing... If that IS a 350 Case, there's no way a 2 ton float would carry it safely, especially with the hoe. A 6 ton tandem would be the minimum..

I agree with Tom. You don't want to put that dozer on a 2 ton trailer and I don't think that you want to put that hoe on a 646.

The complete history as always.

I have no interest in buying that heap of steel, 2 tons or otherwise. My brother and I are doing some painting work on the 646 in my garage and I have been comparing it to the pictures since I found them. He is going to get some more information on the hoe. If it is a D100, he might try to buy just the hoe for spare parts.

Thanks for 411

I believe it is a Davis judging from the swing cylinder. Case always used 2 seperate cylinders mounted low. I'm pretty sure that you will find that it's a 130 though.

I have been searching for a control lever from the D100A for about 2 hours now using internet, and calling anyone in our area. As far as anyone knows they are discontinued and i eaither have to fine a used one or make one. So I cam e across your post and am wondering if you did purchase it for parts or if you know of somewhere I could maybe find one. I was able to find the main mast bearing and new seals for the turn cylinders but no luck with the control lever. I hope to hear from you, and maybe you can help. Thanks Patrick, Mitchell, Ontario, Canada.

My brother talked to the seller and he was not interested in selling the backhoe separately. So, we never went to look at it and hence, no purchase. You are looking in the right places to find the parts that you need. I am sure that some of the knowledgable Colt, Case and Ingersoll veterans on this site can send you in the direction that you need. It is amazing what these guys can come up with at times.

Best of luck with your search. :thumbsup:
