Note: These ebay links won't last for long but I am moving this thread out of the ebay forum so that it doesn't get deleted. It has some good info on the Grizzly below...

These don't pop up too often.

Interesting design, I'd like to see more of how the axles are mounted in such a thin hull. The engine has a drive clutch and belt on both sides with a nice support bearing design right on the clutch.

The hull design reminds me of the http://www.6x6world.com/forums/brand...h-swamper.html

Hey Mike, good call on that! The Bush-Swamper was built in the same place (Sudbury, Ontario Canada) and and I'm going to guess it was the same company (Trans-Tec might have been the parent company of Bristol Machine works) that built the Wolverine. Their US distributor was in Chattanooga, TN.....that would explain why this one is so close, just over the border in Georgia. A couple years ago there was one that was about 30-40 minutes south of this one one I-75 in Adairsville, GA. I wonder if this is the same machine. Isn't that odd how the clutch mounts on the flywheel side of the engine?

Some History

Here is pic of the fellow who was the Shop Foreman for Bristol Machine Works for over 20 years. He built the Bush Swampers. The Grizzly's are basically the same machine only more tires. Both machines have "no hull", just a fiberglass upper shell that keeps you dry.

The drive system starts with a "dual crankshaft" on a horiz. 18 hp. Briggs, goes to 2 mechanical clutched drivers, then to 2 driven clutches that are on the input shafts of 2 reversible gear boxes. From there they go to a chain "drive train" which is housed in an aluminum casting which run down the middle, the entire length of the machine. This casting is only 8" wide, and is the only place where the machine can get high centered. It can counter-rotate as well. The drive train is in an oil bath.

The axle arrangement is very unique, with the axles going right through the "transmission", through driven sleeves (very hard to describe). But fairly easy to remove to fix a flat.

He told me the end of the Grizzly was when the company took Government money to "improve" the machine. When the Government got involved they wanted all kinds of safety stuff and other "improvements" which made them uncompetitive. Sound kind of familiar (US Auto Industry).

One interesting point was how they prepared the machine for shipping. Just before a kid had the job of hooking up a telephone pole and dragging it around the yard for an hour to stretch the chains. After which they adjusted the tension and that was pretty well it for hundreds of hours. Nothing like an oil bath!

It looks like the engine clutch is connected to the steering. Variable drive speed to each side! True 6(12)wheel drive on each side. Pretty cool comfiguration.

Sled!!

It's definately a head turner!! You would think with that many tires, it would have more horsepower.

Hey Mike,So what do you think this thing is worth?Very different and cool! Any input would be great!! Thanks! Steve

Wow

What an awsome machine!

One of my clients has one with the 24 tires on it and a flat be in excellent shape. They are weird looking with that narrow "tube" chassis.
