John Deere’s eHydro system introduces a new element of automation and control not found on manual hydrostatic drives. What can these systems do? Keep reading to find out!

eHydro vs. HST

John Deere uses an electronically controlled transmission called the eHydro, which varies from a standard HST.  Foot pedals on an eHydro send electrical signals to open and close hydraulic valves rather than directly opening and closing the valves manually.


The electronics on an eHydro allow for many programmable features such as: eThrottle, Cruise Control, LoadMatch, MotionMatch, and SpeedMatch.


eThrottle calibrates the engine speed to the pedal position, allowing the operator to keep the throttle essentially all the way in the low position.  This makes life easier on an driver who wants to make the tractor quieter and conserve fuel

Cruise Control

Engaged and disengaged electronically with a button located on the operator console, Cruise Control maintains a set speed without requiring pressure on the foot pedal.  Built in sensors allow the tractor to maintain a preset speed even while driving up and down hills.


Industry exclusive LoadMatch compensates for increased torque requirements and load on the transmission by reducing drive speed as needed.  The controls automatically make adjustments depending on the PTO application, minimizing the potential for stalls.


MotionMatch provides the user with seven settings for adjusting rollout and deceleration.  With the option of longer or shorter acceleration and deceleration distances, operators can achieve better consistency with different applications.


SpeedMatch presets a maximum speed, advantageous for rotary tilling or spraying applications where consistent distance over time is key.  Once SpeedMatch is engaged, the operator strokes the travel pedal fully to meet the preset speed.  This function improves task accuracy and safety, especially when lower travel speeds are necessary.
