Final answer:
The major difference between the hydrostatic drive system and the automatic transmission is the way they transmit power and control the speed of a vehicle.
Step-by-step explanation:
The major difference between the hydrostatic drive system and the automatic transmission is the way they transmit power and control the speed of a vehicle.
In a hydrostatic drive system, power is transmitted through pressurized fluid, usually oil, which is used to operate hydraulic motors and cylinders. This system provides smooth and continuous power transfer and is often used in heavy machinery and vehicles.
On the other hand, an automatic transmission uses a set of gears and a torque converter to transmit power and control the speed of the vehicle. The transmission automatically changes gears based on the vehicle's speed and load, providing optimal power and efficiency.
