Abstract
A power transmission usable with a vehicle and having three ranges or speeds of operation in both forward and reverse directions of travel of the vehicle, including a low-speed range, an intermediate-speed work range, and a high-speed range and having a planetary differential with a sun gear drivingly connected to the motor of the hydrostatic transmission, a ring gear drivable either by the power input shaft or the hydrostatic transmission and a third intermediate planetary gear system connected to the output shaft with selectively operable clutches and gear trains related with the other structure of the power transmission for utilization in a drop box configuration and optional connection to multiple hydrostatic transmission pumps and motors.
