Abstract: A belt tension adjustment mechanism having a pivoting pulley support plate adapted to cooperate with a pivoting ratchet plate. The pulley support plate directly or indirectly anchors a belt to be tensioned. A tension spring is associated with the ratchet plate to bias the ratchet plate towards a position of increased belt tension. The ratchet plate includes a teeth and pawl arrangement for preventing the ratchet plate from spontaneous rotation to a position of reduced belt tension.

Abstract: A vehicle drive assembly includes a rotating shaft driven by an endless belt which engages and travels about forward and reverse pulleys attached to the shaft and also about an idler pulley which indirectly enables rotation of the forward and reverse pulleys in the forward and reverse directions, respectively. The drive assembly also includes an oscillating clutch assembly, operable by a clutch pedal, which allows both selective engagement of clutch plates with either of the forward and reverse pulleys and neutralization of the clutch assembly. The clutch assembly is also operably linked to the vehicle braking system such that actuation of the brake pedal also effects neutralization of the clutch assembly.

Abstract: The shredding machine includes a housing with a lower shredding chamber located in the upper part of the housing. An upwardly extending trunk is mounted on the housing. A hopper is mounted on the free end of the trunk and the lower portion of the trunk constitutes an upper shredding chamber commencing with the lower shredding chamber. An electric motor supported in the housing has its output shaft projecting into the flower shredding chamber. Upper and lower cutting means are mounted on the shaft, the upper cutting means rotates in the upper shredding chamber and the lower shredding means rotates in the lower shredding chamber. A feed duct extends through the trunk and the upper shredding chamber. It terminates just above the lower shredding chamber. The upper cutting means shreds material fed to the machine through the hopper and the lower shredding means shreds material fed to the machine through the feed duct.

Abstract: A self-propelled flail blade lawn mower comprising a support frame having forward and rearward ends, a handle assembly extending upwardly and rearwardly from said rearward end and a cutter housing extending forwardly of said forward end, a rear axle and wheel assembly rotatably supported substantially in the vicinity of the rearward end of said support frame and a pair of front wheels rotatably mounted substantially in the vicinity of the forward end of said cutter housing, a cutter shaft bearing a plurality of pivotally mounted flail blades rotatably supported within said cutter housing a motor and a transmission box mounted on said support frame, said motor having an output shaft and said transmission box having input and output shafts, first drive means operatively connected between said transmission box output shaft and said rear axle and wheel assembly, second drive means connectable between said motor output shaft and said transmission box input shaft in response to the movement of a first lever mounted
