A lawn mower could be a simple outdoor gardening tool which homeowners with a grass patch would require. However, there may be specific features which their lawn mower may offer for a better performance. It would augur well with them if they understand the specific needs of their lawn to identify the best lawn mowing machines for handling their mowing needs.
Hydrostatic Mower Dynamics
There are many kinds of lawn mowers in the market to entice consumers. Progressive technologies bring on advanced features that make the lawn mower another awesome simple machine to be owned in the home. One of the latest developments in lawn mowers is the emergence of hydrostatic technology for the best of hydrostatic mowers in the market.
This type of lawn mowers functions using hydraulics instead of mechanical belts and gears in the operation. The mower is powered through hydrostatic transmission via a hydraulic pump and hydraulic motor. The operational process is simple with a pressurized oil flow by the pump to the mower motor which turns the attached wheels.
Many hydrostatic transmissions use different displacement pumps to provide varying speeds of operation to handle various types of grass cutting exercises. These are also functional using the reversible closed-loop process where the pump has a certain quantum of oil to be circulated within the motor circuit for forward and backward motions.
Such progressive technology could be applied to different versions of lawn mowers like the push or riding mowers. A hydrostatic mower could be controlled via one or two foot pedals or hand levers. A cruise control could be also found in various mower models for a more comfortable operation by the operator whose foot could be released during mowing. An easy step or press would have the mower on its way to execute its task dynamically.
Features of Hydrostatic Mower
The features found in a hydrostatic mower are dynamic to ensure a vibrant mowing task; however, meticulous maintenance would be required to keep the mower in longer functioning mode. The hydraulic oil must be clean at all times with its filters changed every 500 hours. This could equate to once every season after a full operation.
The hydraulic mower has many simple components which must be regularly checked and cleaned to continue its optimal functioning. There are potential leaks in the hose as well as cracked fittings which could easily damage the whole system. This would lead to costly repairs or replacement of parts and eventually, the whole unit.
Nevertheless, hydrostatic mowers are more reliable compared to other types of mowers which are often plagued with costly components and transmission wear.
Advantages of Hydrostatic Mowers
There are distinct advantages for using a hydrostatic lawn mower. Many hydrostatic mower models could be over gear-driven or multiple speeds units with higher power in smaller sizes. Hydrostatic mowers are able to control the speed more accurately with a smooth maneuvering and quicker response.
Mower users are able to change directions even in many challenging corners or tight spaces easily to perform their mowing operations. Hydrostatic mowers function well in various types of conditions; wet or dry. There is the dynamic braking feature which permits very quick or sudden stops with total safety and control.
Disadvantages of Hydrostatic Mowers
There are a couple of distinct disadvantages in using the hydrostatic mower. The cost is certainly a big factor of consideration for many consumers in deciding on this model. It could be twice the price of the normal gear-driven mower units.
The hydrostatic mowers could be less efficient as it requires more power and fuel compared to other mower options. Hydrostatic mower transmissions deploy pressurized oil to empower smooth mower movements particularly for tractor mowers. The pressurized oil fluid would remove any air present in the pump. This condition called cavitation causes potential damage on the pump which could operate dry.
A new hydrostatic mower could have minor problems unless the hydrostatic transmission is purged properly before application. The same goes with a hydrostatic mower which has not been used over a long period. Mower users could experience a loss of power or drive during operation; if not, a slower response by the mower.
Hydrostatic mower users could implement the following procedure in removing any trapped air from the transmission pump.
Step 1 – Position the mower safely on a jack at its rear end on a level surface. Make sure that the engine is switched off and put in the parking brake mode for safety.
Step 2 – Free up the transmission in freewheel control mode which could be found at the rear end of the frame. Have the mower transmission in freewheeling position for mowers using separate pumps. The freewheel is normally activated with a turning of the bypass valves in full turns.
Step 3 – Be aptly seated or positioned before switching on. As the engine is started and running, engage the throttle to a slow position with a full control. The motion control levers should be in the neutral position before the clutch or brake pedal is slowly disengaged.
Step 4 – The motion control levers could now be pushed to a full forward position with a 5-second hold. Then, push the levers to a complete reverse engagement for another 5 seconds. This procedure should be repeated 3 times.
Step 5 – Again, push the motion control levers into a neutral position before shutting down the engine. The parking brake should be set into position. Now, check the oil level for addition using an oil canister.
Step 6 – The transmission could now be engaged with freewheel control positioned for drive. Alternatively, the bypass valves could be closed on the pump.
Step 7 – Start the engine again when the operator is seated securely. The throttle control could now be engaged to full speed. From the neutral position, the motion control levers could disengage the clutch and brake pedal slowly.

Step 8 – Slowly move motion control levers forward, after the tractor moves approximately five (5) feet, slowly move motion control levers to reverse position.
After the mower moves approximately five (5) feet return the motion control levers to the neutral (N) position. Repeat this procedure with the motion control levers three (3) times.
Step 9 – The mower transmission is aptly purged to be ready to function normally.
The mower operation manual should contain sufficient information for a complete purging of the transmission. Consumers could also contact their dealer or manufacturer for the required professional assistance or apt information to perform the procedure accurately. It is possible for the mower owner to execute the mower transmission purging personally with the right information and instructions especially if they are keen home improvement enthusiasts.
Relevant Hydrostatic Mower Info
A hydrostatic mower is part of the modern technology development of simple machines; however, users and owners must be aware of the required regular maintenance for hydrostatic mowers that would ensure optimal performance at all times. This includes the choice of oil in its transmission and apt purging of transmission for greater performance.
Hydrostatic mower owners and users should adopt good basic knowledge of their product to enjoy relevant support from the brand manufacturer or supplier as well as professional service providers in the market as it may not be possible for the owners or users to resolve certain problems encountered. Nevertheless, the Internet offers a host of up-to-date information for excellent effective product support on hydrostatic mower care.
The best of mower operation or performance requires a proper purging of the transmission before the first-time operation happens. This is a critical and essential maintenance procedure as there could have air trapped inside the mower transmission during shipping.
Different models and brands of hydrostatic mowers may have slightly different requirements such as control features, type of preferred operating oil or special fluid change procedures. The respective operation manual would provide appropriate insights on handling each of the issues for the various models; that is, from type of oil to fluid capacities and maintenance requirements.
However, if a fluid loss is experienced, professional care services should be sought after. The same goes for any loss of drive or power for the mower to be evaluated professionally to be restored quickly to optimal performance. A manual transmission roll is possible with the proper know-how according to the manual procedure. The tractor mower on hydrostatic transmission has a lever activates the valve to allow a manual push instead. The “Z” style lawn mower using a hydrostatic drive system has 2 release options which must be activated to roll out the mower.
Never tow the hydrostatic mower which could damage the transmission function.
So basically hydrostatic lawn mower means a lawn mower which operates on the hydraulics technology instead of gears and belts to operate the machine. It has many benefits but it should be used and maintained carefully to get the optimum benefits.
