Hi, Juiceman and CR.
Thank you for that information. I have never seen a scraper like that before and sorta figured that the bowl tipped far enough to lower the cutting into the ground as well as rolling right over to dump. Using the 3-pt lift arms to control digging depth puts a whole different complexion on it.
Seems like Case on a Cat is gonna need either a tractor with 3-pt linkage or a 3-pt system for his D2 - WITH an extra circuit for the dump.
Just my 0.02.

Deas most little farm scrapers are like that with the linkage arms providing the lift and pull, Ferguson made one that looks the same as the one in the video for the little grey Fergy not really much chop for fine work on a grey Fergy as they have no position control just up or down
Theres a Kiwi mob making far bigger ones today and they sell them in Australia www.hwindustries.co.nz/scrapers/ they are no were near as efficient as a draw bar machine as the linkage will not provide the weight transfer and extra traction that you get with a draw bar and stability is also compromised as the linkage machines take traction from the front wheels but for smaller not very fine work they do a pretty good job

If you want to convert to be used to run on the D2 drawbar I would probably cut the front hitch somewhere and put a hinge joint in the hitch and then put a hydraulic cylinder above it to raise and lower the front end.
The other option would have a straight hitch running directly to the cat drawbar and have a hinge joint just ahead of the rear wheels like the more modern laser scrapers like miskin, Reynolds and others.
I don't think you will want a diverter but 2 independent circuits.

I think I would build a simulated tractor three pt and pull it with the D2 just like a jeep. Leave the scraper alone.

Hi, CR.
There is already one horizontal pivot point built into that existing hitch, right under the side-to-side/lateral pivot at the bottom of the 'kingpost' to allow the 3-pt lift to do its thing.. It would need a second horizontal pivot built into the drawbar attachment to the D2 with a hydraulic ram mounted to actuate the connecting link between those 2 points. Depending on how it was done, this may require locking out the 'kingpost' vertical pivot and making the drawbar pin the vertical pivot point. Doing it this way would also reduce the effect of the tractor's up-n-down movements on the scraper 'cos of the extra distance ahead.
Just my 0.02.

Hi
Dp is right in what he said first because most small (older) scrapers in Queensland that I have seen do use the one hyd ram to do cut carry and unload

Deas Plant there was talk at first about making a new hitch to operate on the D2. If you would go down that route the existing pivot point would be in the scrap pile.
Something along this.

A question for scraper operators. Leaving aside allowances in design, speed of hydraulics, etc., can a scraper be successfully operated if the cutting edge lower/raise action, and the ejection action are mutually exclusive events? That is, for example, lower the cutting edge to the cutting position, fill, then raise, then eject, and repeat.
Reason I ask this question is because if the scraper control on a tractor with a single hydraulic circuit to the rear operated such that you could only perform one of those actions at a time, could one still operate those two functions in a reasonably efficient manner? Not talking production machine obviously - just a toy. My D2 has a single spool 27gpm #44 pump and I wondered if a suitable control could be used to operate both functions from the one supply circuit to the rear.

Yes, my Laplante Choate will do all that with one spool, a cylinder on each side. After you raise the bucket to travel, continued input will roll the bucket to dump. A Henry unit I have dumps to the rear with one central cylinder for all movements.
