I have to know.. I can't unsee this and I want one.. It's on..
You need 1…or 2 if you want to race
Definitely don’t Google Mini-dozer.
Made that mistake. What a rabbit hole.
That thing looks super simple. Could get you into a whole of trouble. (I mean fun!).
our local mud bog would be a hoot with that thing..
Try googling Quadractor.
I had a couple of these at one time. Climbed like goats.
Very cool build indeed. I do see one flaw with the "tracks". Mud and snow will build up inside them causing the bogie wheels to get larger in diameter.
I wonder if a hole saw through he middle of the treads would solve that and still have the integrity to stay together?
That probably would solve that. All the tracks I have seen have a way for debris to escape.
Saw the Quadractor at a state fair many years ago and I still have a newsletter from them. I always thought it was a cool idea and some neat engineering.
Looking at the information and manuals, it looked like it had an awful lot of belts and pulleys. I always wondered if they stayed in adjustment.
They were pretty cool.
Yeah, funny combination of backyard and aviation tech, and a lawnmower engine.
The knuckle jointed drive/suspension/steering legs were from aircraft engineering. The drive, transmission, and steering were about a dozen long v-belts. Reverse was done by belts crossed on themselves, and so on. Easily adjusted by idler pulleys.
But it worked. They would climb a vertical wall if you weren't paying attention.
The engineering of so much of that old equipment fascinates me.
I liked the fact that the Quadractor had such high ground clearance and the weight was distributed into the center of the vehicle so it could lift and pull a lot of weight.
I imagine the liability for consumer safety was a huge downside to their survival as a concept.
Interesting. Since the society is so ready to sue, a lot of really well engineered projects never got going.
I once saw a motorized wheelchair that would go up steps locking one axle at a time and the other one going up the steps one at a time. I would think the liability is what killed that.
Chained up, it did pretty well in the snow.
