I know we've had threads about this in the past but I couldn't find them by searching. Can someone tell me what is an accurate estimate of trenching time? I will be using a Case 580L Extendahoe. The trench will be 18"-24" deep by one bucket width & 280 feet long. The terrain is easy digging (no rocks, shale etc.), no obstructions to worry about. Just trying to get an idea of how long the back hoe part of the job might\should take. Its been a real long time since I dug such a trench, so I can't remember. Thanks for any help.
