Purchasing a lawn tractor with a hydrostatic transmission represents a significant financial investment for most homeowners, so it can be particularly frustrating when you experience trouble shifting the machine. Hydrostatic transmissions, unlike those that contain traditional manual or automatic transmissions, use an oil-filled hydraulic pump to control the mower's speed and direction. When shifting problems occur, it's crucial to repair them quickly so you're able to use the tractor in the most effective manner. Benefits of Hydrostatic Transmissions When it comes to shifting and directing the lawn tractor, hydrostatic transmissions rise head and shoulders above other types of transmissions. On a hydrostatic model, you'll never encounter grinding or stuck gears because there are no gears to grind. You also do not need to stop the mower to shift it into another gear to slow or speed up the machine. Simply use the hydrostatic controls to make the change while you're still in motion.

Many manufacturers of hydrostatic machines place hand controls for shifting the mower near the steering wheel for ease of use, rather than requiring you to use a clutch/brake pedal as do other models. Potential Problems Although mechanical problems with hydrostatic transmissions are rare, they do occur occasionally.

A leak of the oil that powers the hydraulic pump will reduce the internal pressure and can cause difficulty in shifting. You may notice the lawn tractor simply doesn't have the power it had previously or doesn't respond to your shifting. It's also is possible the transmission control arm may be out of adjustment, affecting its performance when you shift the machine. If the tractor's wheels continue to move when the machine is in neutral, it's time to access and adjust the adjustment bolt. When there is no response to your movement of the shift control arm, you may have activated the manual bypass lever. Useful for towing or pushing the lawn tractor, the manual bypass lever will stop the tractor from responding when you push the control arm until you disengage the lever.

Operator Error If you're new to using a hydrostatic tractor, simple operator errors may fool you into thinking you have a shifting problem. Before you jump to conclusions, ensure you've released the parking brake before shifting the machine or the tractor will not respond to your adjustment of the control lever to move forward or backward. Trying to shift while using the cruise control feature may also make it appear there's a shifting problem. As long as the machine is in cruise control mode, you will be unable to shift to a higher or lower speed; disengage the cruise control before attempting to shift. Hydrostatic Transmission Repairs Since most hydrostatic transmissions are completely sealed within a steel or metal casing, they aren't accessible to the user when it comes to repairs.

Rather than risk voiding the warranty that came with the lawn tractor by attempting to work on the hydrostatic transmission yourself, seek out an authorized service representative to perform diagnostics or make repairs. Troubleshooting and repairing a hydrostatic transmission is beyond the scope of the average homeowner, who likely doesn't have the appropriate tools, training or knowledge for the job.
