The mower cannot be rolled because the neutral rod doesn’t disengage the tranny. The wheels spin in opposite directions by hand when lifted off the ground. It was working fine up until then.

How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
One of the disadvantages of hydrostatic drives is that the majority of the oil stays in the loop and doesn`t return to the reservoir for cooling. One way to return some of the oil back to the tank is by using a hot oil shuttle valve.
Although cavitation is much more common with hydraulic systems, it can also seriously damage hydrostatic transmissions. Caused when gases in the fluid vaporize, it`s characterized by noisy, erratic transmission operation.
Hydrostatic transmission with locking differential – The dual-pedal drive operated hydrostatic transmission offers a smooth, variable forward and reverse speed while the standard automatic locking rear differential increases traction while cutting on slopes or wet grass.
Air in the hydraulic fluid makes an alarming banging or knocking noise when it compresses and decompresses, as it circulates through the system. Other symptoms include foaming of the fluid and erratic actuator movement.
They are filled with the specified pump fluid to match each pump design and then sealed by each manufacturer at their factories. Replacing hydrostatic fluid is normally not necessary, unless the drive system is in need of some other internal service or repair.
When air is present in a hydraulic system, the desired instant system reaction is slowed and results in a slower actuator response or a “spongy feel.” This is due to the compressible nature of the trapped air. The air contained in a system is alternately compressed and decompressed as the actuator is cycled.
When air contaminates a hydraulic fluid, usually via the pump`s inlet, aeration, cavitation, or foaming can occur. Aeration is bad news, as it degrades the hydraulic fluid causing damage to the components of the system due to loss of lubrication, resulting in overheating and burning of the seals.
The HT-1000 transmission fluid only needs to be changed once every 1000 hours, as opposed to as early as 500 hours with other brands. Our Hydrostatic Transmission Fluid HT-1000™ is a synthetic transmission oil engineered to provide maximum durability and long life for heavy-duty hydrostatic drive systems.
Although the life of a hydraulic oil really depends on many variables, including quality of oil, operating conditions, and potential contamination, a good quality hydraulic oil should last at least 6 months if conditions are not severe.
The fluid recommended for Hydro-Gear transmissions and pumps is a 20W-50 motor oil or 15W-50 synthetic motor oil. If the machine has oil reservoirs, they are mounted to the frame behind the seat, for easy access and oil level check accessibility.
Not as powerful as a manual tractor: Hydraulic transmissions don`t transfer engine horsepower to PTO horsepower as efficiently. Requires professional service: Closed transmission system dictates that any transmission repairs need professional expertise.
In tasks such as moving manure or compost, hydrostatic transmissions are preferred due to their ability to switch from forward to reverse instantly. A second positive is that you can control the speed and direction of travel with your foot, leaving your hands free to focus on steering and operating the tractor loader.

What is a hydrostatic transmission? Simply, it is a hydraulic system where the hydraulic pump or an accumulator will drive the motor using the fluid passing through flexible hoses. In hydrostatic transmission, gears are not required for converting rotating mechanical energy from one source to another.

The engine idles way too fast and will not correct with the sow speed adjustment
ANSWER : Make sure that you are adjusting the idle speed screw, not the idle jet screw (L). If you are adjusting the proper screw, then it is possible that the throttle trigger assembly in the handle has a load of sawdust/dirt that blocks proper return to idle. Take the handle apart carefully, and make notes on how the parts go back together. Check at the carburetor throttle assembly to make sure the throttle arm returns fully to the idle speed screw when the trigger is pulled and released slowly. Check the throttle spring as well to make sure it is undamaged. Hope this helps!

Idle goes up and down and the shuts off eventually
ANSWER : It sounds like the engine might be running too lean. You need to get someone to adjust the idle and high speed screws correctly.

I have a craftsman 42″ hydrostatic riding mower with an 18hp twin that has been getting slower with each use lately.The last time I mowed,I couldnt go up any inclines while on the tractor,if I got off it would slowly advance.Seems to be getting worse.Is it such a thing…low on fliud would cause this or could someone offer some advice.Thank you to whom ever may help!
ANSWER : Yes low fluid would cause that also contaminated oil….and drive plates wearing out as well

Hydrostatic tractor won’t move forward or backward. I release the hydrostatic lever but it won’t move.
ANSWER : Check the fluid level. Can you push it when it is in gear? Have you added any fluid it may have to be purged. Also do you use a pressure washer or water hose to clean it up or does it set outside it could be getting water in the transmission.
