Bucket Fill or Cycle Time? John Deere

15/1/2015· The reason for this is the excavator cycles faster than the loader. Using a loader, the operator will cycle 2 to 2.5 times per minute, so bucket fill is more important. When using an excavator, the operator cycles 4 to 5 times per minute, so the operator on the excavator will maintain a constant bucket load and go to get a faster cycle.
