Hi, Case on a Cat.
Priorities? Yer gotta do wott yer gotta do - and keepin' the cash flow happ'nin' is usually pretty high up on most people's lists.

Glad ter be of assistance - if I wuz - in keepin' ther missus frum blowin' a gasket. LOL.

My wife was skeptical that the scraper was worth it

I can guarantee after spending all day on shovel and wheel barrow she will be convinced your scoop was a good investment and you will find it a lot more useful than you think because you have it right there to use

good luck with the new house

Just because you are talking about 3 point lift. Here's one on a D4 I have

Hi, Skinner.
It's not doing Case on a Cat any good there. Get it on a truck and over to his place at Perris, CA.. LOL.

Neat looking arrangement. Thanks for sharing.

Just my 0.02.

I have gone back and forth on a category 1, 3pt hitch for the D2. I started collecting parts for a 3pt hitch last summer. I figured that with my fabrication abilities anything is possible. However one implement I could use is a good ripper. I've been lurking in the archives while working on my holt blade. I looked at the back up rippers behind the blade, but decided against it because of the wear and tear on sprockets ect. I also looked at rigging rippers on the back, but found several warnings that the back of a D2 was engineered for heavy use with the draw bar and that's pretty much it.

The other problem with a 3pt on my D2 is the top link length. It's hard to tuck the hitch under the tank without having a short top link. I'd have to use a cylinder to constantly adjust the 3pt's parallel. Then I'm back to adding complicated and typically expensive hydraulic systems, not to mention the seemingly rare find of factory #44 units with multiple valves. I have the PTO unit on my D2 and still might make a 3pt someday. Maybe I'll get a second D2 and use one for pulling and the other with a 3pt, or I could just use one of my wheeled tractors too.

Besides reading the archives, I found 2 adds on craigslist that finally shifted my thinking to a pull scraper and the possibility of other implements pulled from the drawbar. One add is a pull scraper like the one I just bought, but was way over priced. It has rippers pinned onto the front just like a small Gannon. The other add (and I am still contemplating this) is a cheap Killefer ripper implement. After seeing the alternatives to the 3pt, I've realized it's probably easier to do and better for the D2. Once I have the scraper functioning on the D2, I plan to add skirts on the pan to add carrying capacity and make a simple ripper rack.

Hi, Case on a Cat.
Firstly, the top link on a 3-pt does not hafta be straight. You could manufacture the link with a bend in it to fit around the seat when raised and have your turnbuckle adjustment from the bend on out. You would simply need to design the top link with sufficient strength to resist further bending or straightening at the bend under load. this would make it heavier than a normal straight one would need to be but not beyond reason.

Rippers for D2s and early D4s pre-D-series - The Cat 941 track loaders, basically a D4 back end, had an arrangement with a triangular brace as part of the ripper assembly. This brace had its front end pinned in the normal swinging drawbar pull point under the tractor and its 2 back ends bolted to the bottoms of the ripper towers with shims for adjustment so that the main pull load from the ripper went direct to the drawbar pull point under the tractor. They even managed to have a drawbar at the back by fabricating a heavy channel between the ripper towers. The ripper towers were essentially a 1-piece arrangement on a base plate that bolted on in place of the normal drawbar swing frame but the triangular brace under the machine too pretty much all of the load off the back end and transferred it to the drawbar pull point under the tractor.

Somebody may be able to scan this arrangement from a 941 parts book and I think the 951s had a similar arrangement for their rippers.

Hope this helps.

d5 and d6b had a similar thing also dees i have one here off a d5

Hi, Keloz.
Would you be able to post a photo of your D5 brace to show Case on a Cat what they look like? They say a picture is worth 1,000 words. If you can't post a photo, e-mail it to me and I'll put it up. Thanks in anticipation.

The top link on 3PL shouldnt be parallel with the link arms the linkage wont work correctly if it is as no traction will be gained it is just like hooking onto the piece the draw bar slides side to side on it gives no transfer of load and in fact will decrease traction

The top link should be set to supply the traction you need by adjusting weight transfer towards the front or the rear of the tractor as required

the more you want to transfer the steeper the top link should be the less load you want to transfer the link should point further to the lower front of the machine
and under no circumstance should the top link be anywhere near parallel to the ground when working no matter what you have on the linkage as it will make it unstable

So in a long winded way the top link shouldnt be parallel with the lower links unless may you have a linkage mounted spray tank and the jets need to be at a certain angle to the ground

this applies equally to wheeled and tracked tractors all to often I see poorly designed 3PL set ups on crawler tractors that make the tractor more unsafe than people can expect and it is solely due to people not having a good under standing of how 3PL and load transfer has to be set up

Here is a what Deas is talking about.
