“Cute little classic farm crawler tractor / dozer. I believe this is an Oliver OC-3-42 42” gauge tractor, probably late 1940’s or early 50’s. As I understand it, the Celtrac HG & Oliver OC-3 are the same tractor, so it could be either. This one has been rengined with a Willy’s Jeep flathead 4 cylinder gas motor. The tractor starts and runs well (12 volt) and all gears work as do both steering clutches. The sheet metal is in decent shape although the bottom section of the grill appears to have been cut off.

Undercarriage appears to be in decent shape.

The hydraulic on the tractor are weak, probably due to a pump problem though it could be as simple as a relief valve issue. They are strong enough as is to lift and lower the blade, so the tractor can be used as is.

The only other problem I know of is a minor coolant leak that appears to be from the radiator. This is not bad enough to be a problem running the tractor for at least several hours, but does require the radiator to be topped up every few days or so.

This is a good little ranch or small farm crawler – it’s small and light enough to be easy to haul (4-5,000 lb) and with the jeep engine has plenty of power. Works well for light dirt work and would be very good with a disc or similar – even being as small crawler it will still pull as much as a medium sized wheel tractor and be much better in mud or loose dirt.”
