My experiences:
Have planted "baled" moist Coastal sprigs (got them from a commercial spriger farmer) with a single bottom mold board plow, early in the spring when the temp is cool, not cold, and the moisture is prevalent.
Open a furrow, take the "flakes" of the bale and one at a time walk down the furrow dropping in the sprigs pretty close together, falling as they may. Follow that with a 3 pt. regular blade scraper and rolling the dirt back over them and coming back a last time with the tractor tire to mash the ground flat over them. On what my clothes and I looked like when finished, dare not go in the house looking like that. Hosed myself and my clothes down real good afterwards and snuck in the house. Made it. Grin. Commercial spriger guy was booked up tight and had no time for me so I improvised.
Used to lease a lot of property. One such place is next door. Lots of round Bermuda plots in what is otherwise weeds where I fed Coastal bales. I don't understand that mechanism as I read and always heard you had to sprig Coastal. Well maybe so, maybe not. It took without sprigging in many places.
On my current Coastal/Common patch I have an old disc harrow that I welded the discs such that they are aligned straight so they don't disrupt the soil, just cut it and piled on cured bags of Sacrete to get some good weight and cut the shoots which as others have stated, make a new plant for every node. In the spring I run over the patch with my lightweight tractor pulling it several times.
Bermuda loves to be fed, especially N. It rewards you nicely for your effort....course mother nature has to help out with adequate moisture and sunshine.
I think you got some good ideas from others for your requirements.
