Clip Rate (Reel Speed) To achieve a consistent, high quality of cut and a uniform after-cut appearance, it is important to match the reel speed to the height of cut. Important: If the reel speed is too slow, you may notice visible clip marks. If the reel speed is too fast, the cut may have a fuzzy appearance.

Troubleshooting Understanding the Diagnostic ACE Display The machine is equipped with an electronic controller that controls most machine functions. The controller determines what function is required for various input switches (i.e., seat switch, key switch, etc.) and turns on the outputs to actuate solenoids or relays for the requested machine function. For the electronic controller to control the machine as desired, each of the input switches, output solenoids, and relays must be connected and functioning properly.

Note: The red text on the overlay decal refers to input switches and the green text refers to outputs. The “inputs displayed” LED, on the lower right column of the Diagnostic ACE, should illuminate. If the “outputs displayed”...
Page 69
If each output switch is in the correct position and functioning correctly, but the output LEDs are not correctly illuminated, this indicates an ECM problem. If this occurs, contact your authorized Toro distributor for assistance. Important: The Diagnostic ACE display must not be left connected to the machine. It is not designed to withstand the environment of the everyday use of the machine.
