Old Dynamark 26" blower 7 hp

This is a Massey-Ferguson branded Dynamark--thanks to this forum for helping ID it.

It seems like a sturdy old blower but I have zero experience with these. Main problem so far seems to be that both augers are solidly rusted to the shaft. (Why do so few old machines have grease fittings on the augers...?)

Instead of skids it has 6" steel disk wheels, both of which are worn and loose. Would it be better to repair these or to install ordinay steel skids? Opinions?

Personally I use skids though wheels should work too.

As far as the auger rakes being rusted on, that's a common problem with a lot of machines. Most times you're going to have to disassemble the auger housing to gain access to the parts you need to work on. Many times a combination of heat, penetrating oil and pressure can get them loose. Recently there was a thread on using a pneumatic rivet tool to assist breaking them loose. Others have taken out the sheer pins and used the machine in heavy ice and snow and at times had it break loose that way.

Thanks for the response.

Of the several old blowers I have around (they seem to breed in dark corners) the only one without at least one stuck auger is an Ariens. Probably not a coincidence that it's the only one with zerks on the auger tubes. Any that I take apart are going to have zerks installed.

Check to see if it's the wheels bore that's worn or if it's just the shouldered bolt that loose and or worn. The bolts are fairly easy to find. My '70s Craftsman had the same problem and a pair of new bolts fixed it.
I got them at fastenal. I think the shoulder is 1/2" X 1" and the bolt is 3/8"-16. They tend to rust up each year. Always wanted to take the time to drill the wheels and add a grease zerk to them.
