If you go for a scraper blade DEFINATELY get a tail wheel so you can get a high quality finish. If someone says you can carry the blade on the 3ph and skim a good finish they don't know what they are talking about. I used to do footpaths, residential and commercial builing sand pads and a tail wheel is a nessecity.
In short a scraper blade needs to be able to offset to the outside edge of the tyre when angled and tilted, then when you have cleaned your ditches ,pull the material onto the road and lower your tail wheel to do finish work. Note, some tail wheels can be flipped up so you can reverse the blade. I reccomend you avoid the fixed tail wheels.
Weather you go, all manuel , all hydraulic or mixed is up to your budget.
