I will be running long runs of electrical and water supply from one barn to another...probably about 500 feet distance. I would like to use my 85 horsepower JD for this and was thinking about something like the TSC Subsoiler....a very small deep plow that is just dragged behind and supposedly carves a trench in the ground. Soil is dense clay in Georgia. Any advice on what to use and tips for making the job go better? Am thinking if I just buy the subsoiler from Tractor Supply it will break off since my tractor is way over-rated for it.
