Chains for 6 wheel drive

[billbo911]

Another alternative that I don't believe has been mentioned yet is:
Direct drive one set of wheels, then use chain to drive the sets.
For instance, direct drive the center set, then run a chain from center set to the front set and another from the center to the rear set. This can also be done by driving either the front or rear set of wheels and then chaining up the remaining sets. If you use #25 chain, this will also yield the lightest use of chain.
We have used this setup, as well as many other teams, with great success. The one caveat is to make certain your alignment and tensions are correct.

One not so obvious advantage to this design is that a single chain break will not cripple your drive train. In fact, multiple breaks might not either.
