Abstract: A power train for a vehicle includes a gearbox with an input shaft and an output shaft and is configured such that the input shaft drives the output shaft at a single speed ratio in a first direction and a single speed ratio in a second direction. The output shaft is coupleable with the front and rear vehicle axles to separately drive each axle. Further, a continuously variable transmission is connected with an engine shaft and with the gearbox input shaft such that the engine shaft drives the input shaft within a range of speed ratios from less than 1 to greater than 3. Front and rear differentials are coupled with each axle and with the output shaft and drive the axles at different speed ratios such that a base surface drives the front axle independently of the front differential when at least one rear wheel rolls upon the surface.

Abstract: The present invention provides a snowmobile with a reverse-shift lever. A shift cable extends between a transmission which is shiftable from a forward condition to a reverse condition and a lever means of the invention. The lever means is mounted on the snowmobile and includes a lever arm having first and second sides which may be moved from a first, forward position displaying its first side and second, reverse position displaying its second side. So moving the lever arm causes the cable to move, thereby shifting the transmission between its forward and reverse conditions. The first side of the lever arm may include an indicator indicating a forward condition of the transmission and the second side of the lever arm may be provided with an indicator indicating a reverse condition.
