TrenchingEquipment

https://www.youtube.com/watch?v=ur8nbEJxXD8 We are working on installing a more elaborate water system before winter strikes, but we ran in to a huge problem: we needed to dig a trench on a 47 degree slope that had lots of tree roots and was full of rocks. This exact situation made it not ideal for an excavator OR a Ditch Witch, meaning we had to get creative. Jesse remembered that he knew someone that had a tool that used air to dig through soil, and he thought it just may do the task, so he gave him a call to see if we might be able to borrow it. Miraculously, he said yes, and we got to work! While we were off to a slow start due to a learning curve, this tool surpassed our expectations and we now have a 200' ditch 3' deep that we dug using air! Now, we're on to more challenges to getting a cistern and plumbing system in before winter, but at least our ditch is dug which we thought would be the hardest part!

== Trenchers and Vibratory plow ==
Trenchers are used to cut a 20cm wide ditch into the soil for the laying of MDPE or HDPE(See CableJettingAndPipes) Through these pipes copper and fiber is pulled for a Telephone exchange. BR
To cut a very thin slit to lay direct burial cable see VibratoryPlow.

=== Ground preperation before trenching ===
If possible soak the soil with microsprayers for a two days before trenching. Large rocks through which the trencher 
can't cut is broken up with a JackHammer.
