IMPROVED DRIVE AND SUPPORT FOR MIXER DRUM ABSTRACT OF THE DISCLOSURE Certain improvements are provided to the mechanical aspects of a tilt mixer which include a novel boggy, adjustable roller arrangement on the drum track which produces an improved distribution of the stresses produced by the extremely heavy rotating drum which reduces the wear on both individual rollers and on the track. An unique dual staggered tooth gear drive is provided having two spaced sets of teeth each addressed by a pair of motor shaft mounted drive gears on each of a pair of flanking motors in which the teeth of the two sets are staggered or offset by one-half of the gear pitch. This produces a tighter, quieter drive wihch has been found to reduce gear wear. In addition, a unique torque tube system wihch possess a great deal more strength than previous drum tilt axles is provided to support the pivotal action of the drum thereby enabling the tilt point of the drum to be moved forward toward the discharge end of the mixers. This, in turn, reduces the amount of clearance height necessary beneath the drum upon discharge of the drum contents.
