Can you push start a hydrostatic mower?
You can't push hydrostatic mowers without disengaging the transmission. Fluid is pumped to the wheels to turn them, so if the motor is off the pump is too and the wheels won't turn. If you push the mower when it's off, the fluid already at the wheels will flow back into the pump and damage it.

How Does Hydrostatic Transmission Work?
A hydrostatic transmission uses the power from a prime mover, such as the crankshaft of an internal combustion engine, to operate a hydrostatic pump motor. So, the rotary motion from the engine is used to pressurize fluid, which is then directed towards a hydrostatic drive motor. To accommodate the pressurized fluid, the pistons of the drive motor have to start moving, thus creating a rotational motion which turns the wheels. The fluid used is generally oil.
Did You Know?
The Honda DN-01 motorcycle is the first consumer road vehicle that used a hydrostatic transmission.
What is a CVT transmission?
The changing of gears, either manually or automatically, creates disruptions in the power transmission of the vehicle. This means that the engine power reduces momentarily when gears are being changed. This problem can be solved by using a continuous variable transmission (CVT), also called a gearless transmission. The most famous type of CVT is the hydrostatic transmission, which finds application not only in heavy equipment, like forklifts, agricultural tractors, and industrial machinery, but also in vehicles, riding mowers, and even tanks.
How does a fixed displacement pump work?
A fixed-displacement pump helps maintain constant power, while the speed and torque can be changed by varying the motor displacement. Lowering the motor displacement will increase the speed, and increasing it will produce more torque.
What is CVT in motors?
This problem can be solved by using a continuous variable transmission (CVT), also called a gearless transmission. The most famous type of CVT is the hydrostatic transmission, which finds application not only in heavy equipment, like forklifts, agricultural tractors, and industrial machinery, but also in vehicles, riding mowers, and even tanks.
What is the fluid used in a motor?
The fluid used is generally oil. The pressure and amount of fluid sent to the drive motor dictates the speed at which the wheels move. This is controlled by a swashplate, which is operated by a hand lever on the equipment. When the swashplate is vertical, no fluid is sent to the motor, and it is not operated.
What is hydraulic pump?
The hydraulic pump, drive motor, and other components are all enclosed in a common housing, with the motor and the pump sharing a common valve. This enclosed assembly is then bolted to an axle. This type is compact and ideal for applications with space constraints, besides being economical.
