The preferred embodiment, shown in FIG. FIG. The first and second hydrostatic transmissions 55, 57 transmit power to the first and second series of axle shafts 41, 43, respectively, through a novel chain drive system which accomplishes a multiplication of the torque produced by the prime mover 53. milwaukee easy load string trimmer head Matriculate Ahora! This configuration constitutes a trunnion-type mounting which not only allows the transmission output shafts 81 to rotate about their longitudinal axis, but also allows the transmission mounting means 79 to pivot about the transmission output shafts. A resilient means 189 connected to both the first and second control rod levers 181, is biased to produce a force which tends to resist movement of the first control rod lever 181 in a counter-clockwise direction and the second control rod lever 185 in a clockwise direction as viewed in FIG. as viewed in FIGS. Max. power originating from secondary power source, Steering non-deflectable wheels; Steering endless tracks or the like by differentially driving ground-engaging elements on opposite vehicle sides by means of a single main power source using gearings with differential power outputs on opposite sides, e.g. The effect is to prevent the vibrations produced in the chassis by any undulating terrain over which the vehicle travels from being transmitted to the prime mover 53 and hydrostatic transmissions 55, 57, and also to prevent prime mover vibrations from being transmitted to the chassis. Notches 17, 19 may be placed in the body to act as a hand grab, and foot step respectively to aid vehicle passengers in entering and exiting. chassis frame on which a vehicle body may be mounted, Understructures, i.e. An amphibious all terrain vehicle as defined in claim 10, further characterized in that said vehciel operators control means includes: a vehicle operators control shaft mounted in said control actuating joint adapted for motion, relative to said control actuating joint, through a vertical plane substantially transverse to a longitudinal centerline of said vehicle; means defining an elongated slot in said platfrom adapted to slidably receive said operators control arm; means defining a plurality of notches spaced apart along a longitudinal edge of saidelongated slot adapted to receive said operators control arm, each of said notches corresponding to a particular transmission ratio; means defining a gate located between a series of said notches corresponding to a forward motion transmission ratios and rearward motion transmission ratios to prevent a vehicle operator from inadvertently placing said operators control arm in an undesired notch; and. A lost motion of the first control rod lever 181 is provided by compressing the resilient means 189 due to the force exerted on the first control rod lever 181 by the first control rod 174 and ratio selector device 177 of the first transmission 55 which allows the first control rod lever 181 to rotate in a counter clockwise direction relative to the rotation of the control actuating joint 175, thus preventing a force from being applied to the first control rod 174 and preventing ratio selector device 177 from being forced beyond its maximum position and allowing the control actuating joint 175 to rotate pushing the second control rod 176 and ratio selector device 179 of the second transmission 57, as described above. 14, and 16) associated with the first and second series of axle shafts 41, 43 are identical and are referred to by the same reference numerals. 12. 1 claim: 1. 9 is a front sectional view of the chassis also taken along line 8-8 of FIG. 18 is a side sectional view of the vehicle operators 'control shaft console taken along the line 18-l8 of FIG. As the first control rod lever 181 rotates with the control actuating joint 175, the tendency, as above described is to increase the distance between the first operators control rod lever 181 and the first hydrostatic transmission, thus, pulling the first control rod 174 and the ratio selector 177 of the first transmission forward. Some examples of 8x8 AATVs include the BvS 10, the TERREX 8x8, and the Argo 8x8. 9 utilizes one resilient means .73 situated between the power package mounting bracket 67 and the floor pan 25 of the chassis 3. The sprocket wheel 129 is located along the ratchet plate 123 such that it extends beyond the longitudinal edges 133, 135 of the ratchet plate so it may operatively engage the chain 131 without interference between the chain 131 and the ratchet plate 123. 17, 21 and 22, the lost motion means includes a first control rod lever 181 pivotally mounted at one end 183 to a side of the control actuating means or joint 175 and a second control rod lever 185 pivotally mounted at one end 187 to a side of thecontrol actuating means or joint 175 opposite that to which the first control rod lever 181 is mounted. 1.
