7U D4 with Tool Bar and Subsoiler

In 13 years i been known as a toolbar geek i ain't seen a setup like that. 3 different tbar parts books nothing. But maybe in a sales brochure on a d6. I'll have to look for it. The tag reads no.2 tbar for a d2. How are draft beams fastened to the track frame? Most time, moles don't run more than 12", don't loose it running that deep or shallow. I been looking for one 10 years. Is your shin only captured top and bottom? Should be some welds between. What size are your bracket bolts, 3/4 or 7/8? Looks like original point but welded on to last? Don't loose it, NLA. I had to make new using AR flat stock. NEAT, NEAT and most DELUXE! thanks 4 showing it, and good luck.

Here are a few more pictures:




The "insert" appears to be the stamping that came out of the "crank assembly". It is not flame cut.



The 4A "C frame group" unbolts at the trunion and is removed to install the draft arms.

I agree that the lift arms and links are shop made. The original owner told me that the two technicans that did the work "came from Peroia in a yellow Caterpillar service truck to do the work". Could well have been from the dealership (Beckwith Machinery). He also said they were working from a "blue print" (maybe a shop drawing?) when they did the installation.

The pins that fasten the draft arms to the bar brackets are 1.5", the bolts that hold the subsoiler to the bar are 1.25" x slow thread, square head (there is a lip that captures the square head on the bottom). All of the pins for the "beam tilt adjusters" are 1.125".

I our soil we always ran the mole deep- getting through a layer of clay. I did lose it once- was paying close enough attention that I felt the pull get easier. It was a miserable job getting it out. We never did a job that we couldn't run the mole at full depth- a few times I would make a pass without the mole followed up by a second pass.

I have a D46U with the #4 toolbar with the front blade and the bar with a single subsoiler. I was just out in Stockton CA, and found a dealer that had 4 different #4 toolbar parts books. I bought them all, he also had a #2 and I will look to see if any of these parts are in them.

I will try to post pics of my rear toolbar pieces. I am missing the front shin for my ripper.

In the parts book it list at least two different ripper shanks, and the one above is different than mine.

I called CAT and the shin is no longer available, but they will give me the specs so I can have one made.

Neat item.

Here are my pics.

Michael-

When you get the shin dimensions, can you post a drawing? Thanks

Cool tractor-

Looks like a Balderson lift arrangement, however I can't locate my literature to confirm at this moment.

i think u got it, as said above, i too seem to remember seeing this somehow/somewhere. problem is getting thru hundreds pages of brochures. good luck.

ps, how many farmalls could u buy with the cost of that d4 back in the day?????????

pss, phil my shins looks tobe just flat stock the same thickness as the s-soiler by 1 1/2", not bevel sharpened just factory blunt edge. this is the only way i seen them on the 4-5 old cat s-soilers i seen.
