What goes wrong with hydrostatic transmission?
By far, the most common reason for hydrostatic transmission failure is old hydraulic fluid. John Deere states that "Operating outside of the recommended oil air temperature range may cause premature hydrostatic transmission failure." Oil must be changed when its anti-foam additive decays.
Why won't my hydrostatic mower won't move?
A hydrostatic lawn mower may not move because of a bad drive belt; bad tensioner pulley; broke tensioner spring; old or low hydraulic fluid; hot hydraulic fluid; air in the hydraulic system; or the drive release handles are in the “released” position.
Can you push a ride on lawn mower?
A riding mower can't be push-started, although the engine is coupled to the rear axle via belt and pulleys it won't transfer lateral motion of the belt into rotational motion of the engine. There are two common riding mower transmission types, the oil-driven Hydrostatic tranny, and the manual transmission.
Are hydrostatic lawn mowers good?
In general, hydrostatic transmissions offer high power in a compact size, maintain speed more accurately, and deliver a wider range of speeds that can be easily controlled. Hydrostatic mowers also maneuver smoothly and respond quickly, so users can change directions in tight spaces without difficulty.

How does a hydrostatic transmission work?
The hydrostatic transmission transmits energy using hydraulic fluid. The usual transmission has two hydraulic devices; one working as a variable displacement pump and the other working as a motor connected by hydraulic lines.
Riding Mower Transmission Types
Just before we get knee-deep in transmission types, although I’m sure you are keen to know all about transmissions. It is worth noting not all riding mowers have the secret transmission maintenance mode lever I’ve mentioned above. And that’s because not all riding mowers need one.
What Is Riding Mower Transmission Maintenance Mode
We don’t need to spend much time on this, I think you get the picture. Maintenance mode allows the technician or DIY’er to disconnect the wheels temporarily from the hydrostatic transmission known as releasing the transmission or maintenance mode.
How to Engage Riding Mower Transmission Maintenance Mode
Engaging the maintenance lever is as simple as you imagine it is. It’s typically a lever that the technician pulls or slides across to engage. The hardest part is usually locating the lever. Older mowers can be especially challenging where grime and old grass camouflages the lever. And that’s what we’ll look at next.
How To Locate Mower Transmission Maintenence Mode Lever
Ok, so you know what the maintenance lever does and how to use it, now we need to locate it. As said previously, old grass may help disguise its location and so some cleaning may be required.
Common Riding Mower Transmission Problems
Most folks don’t appreciate how hard a riding mower transmission works, that is until they have to push it. Despite working this hard the transmission isn’t the more common cause of a lack of drive. The most common cause of a lack of drive is a drive belt issue.
How does a hydrostatic mower work?
This oil releases pistons which ultimately result in the powering of the engine through the initiation of the hydrostatic motor which in turn rotates the driving wheels to make the mower move where the driver intends with ease.
What is the advantage of hydrostatic mowers?
Advantage of hydrostatic lawn mowers. As mentioned prior, the main advantage hydrostatic mowers provide is the control. The use of this technology means both speed and direction are handed over to the discretion of the driver much more than other models would.
What does hydrostatic mean in a lawn mower?
Hydrostatic simply refers to the way this lawn mower operates. It brings the use of pressurised oil as its main operation which seems to outdate the established manual/automatic use of gears and belts, providing a much more 21st century gardening approach.
What is dual hydrostatic transmission?
Dual hydrostatic transmission adds an extra feature to the already high-caliber of single hydrostatic transmission. Where single HST requires physical turning of the wheel, dual provides triggers for turning. This means you require even less physical exertion during your lawn mowing experience.
What is manual transmission lawn mower?
Manual transmission lawn mowers are what you would imagine a conventional lawn mower to be like. Whether it be a hand pushed petrol number or a seated mower, manuals require clutch and the necessity to shift gears or push the bad boy around.
How does an automatic lawn mower work?
Automatic transmission lawn mowers are much the same as automatic cars. They operate through the use of the gas pedal in combination with a belt and pulley system , which changes the speed of the machine and allows for easier movement around obstacles.
What to look for when buying a hydrostatic lawn mower?
Perhaps what’s best to look for when buying a hydrostatic lawn mower is what type of garden you have. If the terrain your garden is on is inclined, has many obstacles such as trees and shrubs or requires constant maneuverability, then this mower will make your life so much easier.
Step 2
Set the parking brake and raise the operator's seat. Locate the release valves on the inside of each of the drive pumps. Turn both of the release valves half a turn counterclockwise. Unlock the parking brake.
Step 3
Push the lawn mower to the desired destination. Because of hydraulic drag, the machine push slowly. Turn the release valves clockwise until they are hand tight.
How Does Hydrostatic Mower Work?
The hydrostatic transmission has the most high-powered transmission. The driver does not need to use the pedal to shift.
Are Hydrostatic Mowers Good?
You get benefits from the hydrostatic transmission such as horsepower and pressure limiting, anti-stall, inching, torque, and neutral start, allowing for maximum design flexibility, safety, and precise machine control.
So, How To Know If Your Mower Is Hydrostatic Or Not?
A hydrostatic transmission works like an automatic transmission but uses fluid rather than belts to transfer power from the engine to the wheels. It has a continuously variable transmission (CVT) system .
Frequently Asked Question (FAQs)
The mower is powered by a standard engine. The pump uses pressurized oil to move pistons in the hydrostatic drive system. Then, the pistons’ movement transfers power to the hydrostatic motor and engage the drive wheels on the mower.
How to make a hydrostatic mower faster?
There are lots of ways to make your hydrostatic mower faster. You can put a large pulley and clear the hydraulic drive. Also, you may install larger tires and replace blades.
What causes a mower to stop moving?
The pump influences hydraulic fluid and causes a change in hydraulic pressure. But there is also some vital mechanical component; for example a drive axle and a differential. So any problem with this component may cause a severe issue and prevent the mower from moving.
Why does my lawn mower run in reverse?
If the pressure switches only on one paddle, then the mower may run in the reverse direction. Several problems may occur here. If there is any failure on the hydrostatic drive, then the mower can run slow. You know there is a safety switch under the seat. If the switch is damaged, then the mower will not run.
Why do you need to change the oil on a lawn mower?
Hydrostatic fluid or oil can control the overall speed of the mower. There is a standard temperature requirement for the oil. Any variation in the temperature may affect the speed. You can replace the old fluid with new fresh fluid to improve the speed.
How is power transmitted between the transaxles and the engine?
Power is transmitted between the transaxles and the engine by the drive. Here the drive wheel moves the lawnmower. So you must check any problem with these lawnmower drives. You should acquire proper knowledge to remove and install a new drive belt.
