Looking at a OC6 with a closed cab, front blade. and a ripper. It was restored about 12 years ago. It belongs to a friend of mine who reciently passed away. His wife would like to sell it to me or i could sell it for her. My dalemna is with the blade, i cant find a float position which makes it very difficult to level a road. the model is a OC6-42-g Serial number 1rmz-136 I FOUND A used set of pistons that are for a waukesha six cylinder engine in his shop. That tells me that he installed the new ones. Its in real good condition. Also comes with a four cylinder wi. engine that drives a rotory snow blower that fits on in place of the front blade. I need information like what does the Z stand for and what year is it and is any of this equipment installed from the factory? Any help would be appreciated. CHARLIE K.

I don't know what the Z means in the serial number.

Oliver didn't make blades for their crawlers, but they did work with aftermarket suppliers to have them available. I haven't ever seen where Oliver offered a blade for the OC-6, but that doesn't mean they didn't. They promoted the OC-6 more as a field crawler, rather than an industrial type machine. They did show a loader that could be put on the OC-6, but that was more a farm use setup as well. You ususally had to get a larger crawler to start seeing rippers for Olivers.

Does the blade use a hydraulic unit that is just below the dash, or does it use a pump driven off the engine or PTO? You could add an aftermarket valve with a float position, but how to hook it up would depend on what you have for a hydraulic system.
It looks like it is a 1955 model year.

Thanks Chris. My OC6 HAS A LEVER between the brake levers. Its bent toward the seat. Lift to go up and push down to lower. Its 335 miles up north so Im not sure what the valve looks like. It really looks like it came from the factory . Very professional.Thanks for the information. Charliek.

It sounds like the factory hydraulic system, which is a nice system, but does not have a float position. You could set it up as a one-way cylinder, but then you would loose the ability to put down pressure on the blade. The best option would be to buy an aftermarket, open-center hydraulic valve with a float position, and hook it into the power beyond ports on the hydralic unit. You'd just need to know which plugs and hoses go where, which we can help you with.

Thanks CHRIS, It looks like there is two feet of snow up there. Seems like i will have to wait till spring before i can check it out. Appreciate your input. Charlie K.
