Classic GG Cycle Times
13 Apr 2016
The Classic GG will cycle one sample through the system (from top to bottom) in about 3-4 seconds. This could be slightly lower depending on how fast the sample is feeding and if the system is cycling without any delays (i.e. when cycling multiple times). However, on average, 3-seconds is a good average number to calculate plot to plot speed.
- 3.0 L – approximately 5lb increments
- 1.5 L – approximately 2 lb increments
- .75 L – approximately 1 lb increments
** These numbers are purposefully set with low values to approximate worst case cycle times
There is always a flush cycle at the end of the plot that takes 6-8 seconds after the ENTER key is pressed.
So, for a 3.0L chamber, the system will process 25 lbs in approximately four cycles plus the two flush cycles (total six cycles). Multiply three seconds by four cycles and you get 12 seconds. Add 8 seconds to flush and the cycle time is approximately 20 seconds. Assuming it takes 5-seconds to get through the plot and an extra 5-seconds for the sample to get to the Classic GG and start cycling, the plot to plot speed on a 25 lb plot with 3.0 L chamber is about 30 seconds.
You can see how the plot to plot speed is highly dependent on 1) yield of sample, 2) test weight of sample, 3) chamber size, 4) timer settings, 5) operator delays, and 6) combine threshing / clean-out time. A 30-35 second plot is pretty common in most applications when harvesting a 25 lb plot with a 3.0L chamber.
