  • Hello, Would it be possible to explain to me a problem with our Oliver oc3 Crawler, I have just started to restore it, so it turns over well, i only have a cranck start, so we have no spark on turning it over, would this be timing issue or distributor/magneto problem. Really appreciated if you could help. Regards Kevin

  • I grew up on a muck farm, my dad and grandfather had an OC6 that they bolted 24 oak 2x4s to the tracks. In the spring when we couldn t get on the field with anything else, that old Oliver would almost walk on water. We still have an OC3 from those days.
