Post Driver? Does it hammer them into the ground? I just picked up an auger, so I am set for corner posts. Something to set line posts would be great. Didn't know they made them.
Post Drivers drive posts into the ground!
I use 60mm water pipe posts with bolted fence fittings to create the strainer assemblies, because they never rot or burn.
They are good value, I drill holes with an auger, fill the hole with concrete and bolt it together.
