OC-4 attachments

[sbick]

Have a '57 or so OC-4 with no no blade, hydraulics, or attachments.  Does anyone have a comprehensive list of what blades and attachments will fit this machine.  Also, are OC-3 and OC-4 attachments interchangeable?  Any information would be appreciated.

[Robert Barbour]

From my OC 4 sales lit they made the following attachments.
Loader, dozer, backhoe,winch, post hole auger, post driver( hammer),scraper-scarifer, scarifer ( small ripper) ,side boom, Universal trencher ( similar to a ditch-witch).  For the most part they were made for the OC 4 and the oc 3 would be too small to handel them. Also most are very hard to find!!!!!!!!!!!!

Thanks for the reply and info.  I really appreciate it.  Sorry it took me sooo long to answer.  Yes I would like to get my hands on some of those hard to find attachments and I will keep looking.  I have seen a lot of requests for dozer blade plans/measurements.  Sure would be great if someone could post plans for an Anderson F4 or similar blade and push arms.  Thanks again.

I just recently e-mailed Blake a copy of a brochure for the scraper/scarifier for the '56-'58 OC-4. Maybe he'll put it up soon if he has time. I have noticed that there aren't many OC-4's on this site. I'm going to be on the prowl for some OC-4 literature.

You guys need to remember when the HG and then the OC-3 were produced the prime sales for these units was as a farm tractor. There were also more of those 2 models made than the OC-4 in any of the 3  versions. Also remember early OC-3 tractors were still painted green to compliment the green wheel tractors the Oliver dealer would have on his lot. When the extra transmission speed and roller were added to the first OC-4 more stability for blades and other attachments were provided. Also remember most of these attachments were built by outside vendors and not the Oliver corporation. Later on that changed somewhat. Questions?

I found out a neat little fact the other day. Most on here have said that you know it's an OC-4 if it has four rollers. Well I got my user's manual the other day and it says that the OC-4 tractor had only three rollers. The loaders (and it doesn't mention dozers but i'm guessing these too) have four rollers. Now this is for the '56-'58 models so i'm not saying anything about the '59's up. I thought that was interesting.

the three roller track frame is correct for the early models with the fleetline grille and the 4 cyl. engine. basically the only difference between them and an oc3 is the transmission and sheet metal.

[walter hudson]

also  i have an early 3cyl gas  68 gauge with the second style grille with three roller track frames . does anyone know if the early 3cyl narrow guages only had three rollers ?

Now you guys got me wondering about my machine.
Serial  1TG-444    OC4-42-IND. It has four rollers.

Is it a " Franken-Dozer"
    :shock: :shock:

[walter hudson]

is yours a 4cyl or 3 cyl ? i have been told that all of the 4cyl. models were three roller track frames . there may not a clear cut way to say which oc4 crawlers are 3 or 4 roller .i also have a late oc4 series b that is a wide guage and has 4 rollers , so going by the year or guage may not be conclusive.

[Jim N]

It is a 4 cylinder gas Hercules IXB-3.
When I first purchased it, I called for some parts from Zimmerman and they said it was probably late '57 or early '58.

I have often wondered about the blade set up too, since the hydraulics seem to be the same as those with Andersons   but the blade itself  almost appears to be an incredibly good home made deal.
A couple of years ago, I had it at our home show in Saegertown Pa.  and a guy briefly passed by and said it might have been fabricated at local railroad car shop  a few miles south of here .  (Greenville Steel Car)
 Wish I had been able to talk to him longer......

[walter hudson]

with it being an industrial oc4 ,you would assume it came with a blade or loader. from your picture ,the blade looks taller than anderson's that i have seen .

[GaToy]

Well, my operators manual said only the tractor version of the oc-4 had three rollers. If it was originally set up for dozer or loader hook-up it says it will have four. I would think this would be due to the extra lifting or carring weight.

that is probably true for the early models ,but must not be true for the later model oc4. i have a late oc4 series b 68 gauge that has 4 roller track frames .

Is that one just a crawler/tractor? If so do you have any pics?
