Tuesday's crawler

Oliver OC 3. Pretty much the same animal as an HG. I never had one myself,but Bolthouse used to grow carrots and onions on the muck out east of town and they must have had a dozen of them.

I had an HG with the 20 HP Hercules engine. Fun little machine. Engine was weak and I sold it. Wish I had kept it and put a different engine in it.
Richard in NW SC

I also had an HG, not in bad shape but decided it wasn't going to get restored and sold it.

Thats the best one yet!!! The neighbor in pa who has the Olivers,,,His grandfather had one.That would be late husband of the lady I used to post pictures of.The same lady that taught me how to plant the community turnip patch.When I was around 13 years old,,I would stay at their farm for a week in the summer.My neighbors mom,,who is maybe 3 years older than me,,would go back to NJ for the week and stay with my mom and dad.During one of those stays,,,Ray pulled the little Oliver that looked just like that one under the shade tree.I helped him clean it all up.Then we painted it green with Rustoleum paint,,and good paintbrushes.It actually turned out nice!I wish I had some pictures of that.He sold the crawler before my neighbor was born.MY Neighbor has tried to locate the old oliver crawler,but has had no luck;Thanks for jogging some good memories from this dusty brain!!!!

I have a medium serial # HG which i almost the same as an OC3. Final drives are different. It is still a work machine, and I do not have it as a "collector's item." Very handy crawler. Has a Clark A-30 transaxle as the main transmission and 142 c.i. Hercules IXB3 bored.060" over. Second aux trans is a Ford Model A. It would be pretty useless without that second trans. I built the aux setup myself but Oliver offered it as an option, built by Trasco. Anderson HP221 dozer-blade with hydraulic tilt. Ugly but a great user. I will never paint it. I am building trails with it now in the Michigan Upper Peninsula.

I pulled it out of someone's weeds 20 years ago and paid $700. I went over every moving part and then started using it. Never had an issue since except the magneto failing once in awhile. Still a 6 volt system. Has a standard PTO on back that comes in handy. I rebuilt all the rollers years back and turned the pins and bushings on both sides. Turning them made a huge difference.

Ground speeds with engine in working range:

Original: 1st - 2.01 m.p.h., 2nd - 3.19 m.p.h., 3rd - 5.24 m.p.h., Rev. - 2.33 m.p.h.
Range 1: 1st - .64 m.p.h., 2nd - 1.02 m.p.h., 3rd - 1.68 m.p.h., Rev. - .74 m.p.h.
Range 2: 1st - 1.08 m.p.h., 2nd - 1.72 m.p.h., 3rd - 2.83 m.p.h., Rev. - 1.26 m.p.h.
Range 3: 1st - 2.01 m.p.h., 2nd - 3.19 m.p.h., 3rd - 5.24 m.p.h., Rev. - 2.33 m.p.h.
Range Rev.: 1st - .53 rev. m.p.h., 2nd - .85 rev. m.p.h., 3rd - 1.4 rev. m.p.h., Rev. - .62 froward m.p.h.

Hey, I got one too. Ron MN

No fair,yours is clean. LOL

Here's another one...

We owned an OC3 loader narrow track. It was worn to the nubs. Cylinder wall wear was about .020" It ran is about all that could be said. The real issue was no track steering clutches. Jim

I spent many days on a O C 3 when i was a pup. My uncle was a tater grower and farmed with crawlers up until like 56-57 when he bought a Oliver super 88 but still had the crawlers . He had the O C 3 and a O C 6 diesel with three point and PTO . I first started driving the O C 3 at the ripe old age of 7 and by 9 years of age i was dragging a two bottom oliver trip rope plow . Always loved spring plowing . My uncle and the neighbor across the road worked together and he had A D 4 Cat and pulled five bottoms . The O C 6 had three bottoms three point Oliver plows and with the three in the same field totaling ten bottoms we could cover a lot of ground . same as all tillage work all three would be in the same field at the same time . I still can show you the scare next to my right eye from when the Crank tried to eat me along with the lump on my right arm where it got me when i stalled it one fall afternoon while harrowing the one big field . the battery was dead the gen. did not work and the men had no problem usen the crank or they would park it on the barn bridge hill and coast start it . everyone was working digging taters away from the main farm about a mile away and i was harrowing this biog field getting it ready to plant wheat . When i stalled it i figured i can do this myself , i put the crawler in neutral got the crank and set the throttel three clicks up stuck the crank in and eased it up on compression like i had seen my uncle do many times and with everything i had holding the crank with the MONKEY GRIP like i had been told i gave her a upward pull and Nothing . so we did this again and this time she almost went , so once more i did this and this time she kicked back like a mule the crank spun backwards out of my hand caught me on th3e elbow and flew out catching me up along side the head and laced me a good one . I was now leaking red bodylie fluids . This field where i stalled it was next to the ten acre pond and having a temper i picked up the crank and threw it as hard as i could . Now if anybody needs a crank for a OC 3 there is a like new with some RUST at the boittom of the Deep end of the pond about fifteen -twenty feet from the bank on the south east side just north of the woods.

I agree on need for the auxiliary transmission- you couldn't bulldoze without one, because you couldn't adjust the blade to the terrain fast enough to get anything level. Finding a Model A transmission is easy, but good luck finding a bell housing. I remember seeing an article somewhere on making a bell housing so you could install a Model A transmission (I assume it was in an Oliver magazine). IIRC, they used a piece of 6" well casing, with flat rings welded to both ends to mount it to the transmission and to the engine. Had plans for both rings & the bolt patterns, and the length of casing needed.

I have an OC4, and its got a usable ground speed in low, but still not as slow as I'd like. You could buy the OC4 with either an auxiliary transmission, or a reverser. Mine has the reverser (still need to use the clutch), and I'm glad I have the reverser than the aux transmission.

I made my bell-housing. I just cut the original in half and welded a steel plate to it. I had an OC4 with the "Slo-Lo" aux. It ran .8 MPH in 1st. My HG in the lowest gear runs .6 MPH.

This morning the pic would not show, now it does?

I have this same one in the box . I went on a delivery when I worked for the new Holland dealer' and there was one of these sitting in a corral I wish I had at least tried to buy it
