At least one first driving chain 99 operatively interconnects the first chain driving sprocket wheel 87 to the first chain sprocket wheel 91 of the idler sprocket assembly 89 to transmit power and rotational motion from the transmission to the idler sprocket assembly. An amphibious all-terrain vehicle, which comprises in combination: a chassis having a floor pan,a front wall disposed at one end of said floor pan and situated transversely thereto, a rear wall disposed at the opposite end of said floor pan and disposed transversely thereto, two spaced apart side walls disposed along opposite longitudinal sides of said floor pan, said floor pan being structurally associated with said front wall, rear wall and side walls to form a unitized. Amphibious Ultimate Terrain Vehicle. Home blade amphibious all terrain instructions. 12 and 13) is operatively associated with the chains-of the chain drive system to prevent a chain from disengaging from its associated sprocket wheels by maintaining proper chain tensioning during normal straight ahead operation and/or upon a sudden reversal in the driection of the forces being transmitted by the chain as happens when, for example, the hydrostatic transmissions ratios are changed from a forward direction ratio to a rearward, or reverse direction ratio. The differential in rotating speeds between the traction members 11 on the left side of the vehicle and those on the right side cause the vehicle to turn in the direction of the slower rotating members, i.e. 9 is a front sectional view of the chassis also taken along line 8-8 of FIG. An amphibious all-terain vehicles as defined in claim 7, wherein said chain drive system is further characterized in that: chain tensioning devices are disposed to operatively engage said first, second, third, and fourth driving chains to apply tensioning forces thereto to assure a constant engagement of said first second, third and fourth driving chains with said first chain sprocket wheels and said first chain sprocket wheels of said idler sprocket assemblies, said second chain sprocket wheels of said idler sprocket assemblies and said second chain driven sprocket wheels, said third chain driven sprocket wheels and said fourth chain driven sprocket wheels, and said third chain sprocket wheels of said idler sprocket assemblies and said fifth chain driven sprocket wheels respectively. The lost motion means includes at least two spring loaded control levers each pivotally mounted at one end to the control actuating means. blade amphibious all terrain instructions cascade complete powder dishwasher detergent, fresh scent, 75 oz reef high seas flip flops nursing and health sciences bristol queen low profile storage murphy bed with mattress blade amphibious all terrain instructions blade amphibious all terrain instructions arduino robot car project 8, illustrates the use of two resilient means 69, 71 disposed between the power package mounting bracket 67 and the chassis side rails 33, 35 of the chassis 3. To turn the vehicle while it is moving forward at less than maximum speed, for example to make a right hand turn, the vehicle operator grasps the control handle 149, and without removing it from one of the notches 161 in which it may be located at the time, turns it in a clockwise direction, thus pivoting it in a plane substantially parallel to the horizontal plane through the longitudinal axis of the vehicle. FIG. FIG. It should be kept in mind that theprime mover throttle control means need not be manipulated, or changed to maneuver the vehicle. 15 is a view from the side of the chassis showing a portion of the chain drive system. Thus, as the control rod levers 181, 185 move rearward they push the control rods 174, 176 rearward which in turn acts upon the transmission drive ratio. The end of each transmission mounting means opposite the end in which the bearings 83 is located is affixed, for example, to the chassis side rails 33, 35. The infinitely variable steering and transmission control means, generally denoted as 169, includes a control actuating means or joint 175 (see FIGS. 1'7 is a vertical sectional view of the vehicle operators control shaft console showing the preferred embodiment of the vehicle operators control shaft, the vehic'te operators control means, acutating means, and lost motion means. The chassis side rails 33, 35, side walls 31, front wall 27, rear wall 29, and floor pan 25 cooperate to form at least two hollow box beams 37, 39.. Ain't no mountain high enough. As the actuating joint 175 pivots it causes the control rod levers 181, 185 to rotate through a horizontal plane. 6. Other possible methods of mounting will be obvious to persons skilled in the art upon reading this specification, and are within the scope of the present invention.
