4.4 FREQUENCY OF CUT ______________________________________________________
The FOC (Frequency of cut) is the distance, in inches
(mm), the machine travels forward between reel blades
contacting the bedknife. The FOC can be adjusted either
by changing the Fixed FOC setting or by changing the
maximum mow speed and the fixed reel speed on the
LCD display.
Adjust FOC with Fixed FOC setting
Changing the FOC setting to a value other than 0 will
enable the fixed FOC mode and disable the reel speed
setting. As mower travel speed increases or decreases,
reel speed will automatically adjust as required to
maintain set FOC. The controller only accepts an FOC
range for the 11 blade reel. To set FOC for the 9 or 7
blade reel, multiply the value in the charts by the
following:
9 Blade Conversion ... 0.81818 (9/11)
7 Blade Conversion ... 0.63636 (7/11)
Adjust FOC with Reel Speed Setting
1. Using the FOC charts, determine the maximum mow
speed and fixed reel speed required for the desired
FOC.
2. Start the unit in Superintendant mode. [Section 4.3]
3. Set fixed FOC setting to 0
4. Set desired Maximum Mow Speed
5. Set desired Fixed Reel Speed
NOTE: Mow speed is measured in mph (kph), FOC is
measured in inches (millimeters).
