I own a 3320 with ehydro and the auto cruise upgrade. So here is the deal (info from me and the
manual.
All 3X20s ehydros have load match. LoadMatch enables the operator to prevent the engine stalling during heavy load applications such as operating with a loader. You activate Load Match with a rocker on the left side of the steering wheel.
---------------------------------------------------------------------
All 3X20 machines also have Motion Match. MotionMatch enables the operator to adjust machine acceleration and deceleration rates. Shorter starting and stopping distances can be set for applications requiring rapid changes in direction, such as operating with a loader. Longer starting and stopping distances can be set to avoid turf damage in other applications.
A MotionMatch setting of 1 is the shortest rolling (starting/stopping) distance, and a setting of 9 is the longest rolling (starting/stopping) distance.
Changing MotionMatch Setting
1. Press and hold the display mode switch until the display reads "Release".
2. Release the display mode switch and display should read "Coast".
3. Press the display mode switch once again.
4. For machines without MotionMatch switch:
a. Push the turn signal switch to change to desired setting between 1 and 9. Position 5 is displayed as "DEF", the factory default.
5. Basically if you have the upgrade you have a long and short setting with the rocker. For machines with MotionMatch switch (UPGRADE - switch 3 on the upgrade panel):
a. Push the turn signal switch to change to desired setting between 5 and 9. Position 5 is displayed as "LONG_D", the factory default.
b. Push the turn signal switch to change to desired setting between 1 and 5. Position 5 is displayed as "SHRT_D", the factory default.
6. To confirm the changes for MotionMatch setting, press display mode switch once again.
---------------------------------------------------------------------
All Machines also have cruise. It is the rocker on the right. With the auto cruise upgrade you can increase and reduce speed with the rocker (this is the second switch on the upgraded tractor) instead of having to reset the speed all the time with the pedal.
-------------------------------
The long and short of it - its $86 on a 20K+ tractor - buy it. Or get it later as you can install it yourself.
