To transport the system, he attached the stub axles
and wheels off an old Deere seeder and a junked utility trailer.
It has plenty of tools [24 + 1], and we also have a fourth-axis on it, which we use when we run the machine overnight for making parts like stub axles
. During the day, we use the rest of the bed for other jobs.
In a 4x4 this is done by breaking up the axle into roughly three main parts, the central part containing the differential being fixed to the chassis (and therefore as seen above, becomes a suspended mass) and the two, lighter stub axles
(or half-shafts) driving the wheel hubs via universal and constant-speed joints.
