Both axles on the Aljon's occilate or pivot in the center. I don't think we have ever pushed dirt with it, but it sure moves trash!
Have not heard of Tana, I will do some checking on that.
We had a couple Cat compactors, 826C, no comparison there. The Cats were really bad about wrapping stuff up on the inside of the wheels. Usually would take out the seal. Did not weigh as much either.
The wheels on the new one are made by Aljon, the old ones, and even the Cat, had the Caron wheels.
