We got a gas powered, handheld fence post driver. Ours is made by a company called Skidril (which is how we refer to this tool by now). Probably one of the best tools ever for putting in metal trellis posts. It works so much faster than drilling holes with a tractor attachment, and then pounding in the wooden posts with another tractor attachment. And – with the handheld tool, we can easily replace or add posts when the grapevines or blackberry bushes are already established.
Of course it does take some stamina, and balance and in our case a crew of three people. We marked the field where the posts had to be placed before we got started, and build a platform for the truck for one person to stand on to use the post driver. The second person held the post in place with a level to keep it straight, and the third person drove the truck. They managed to set about 80 posts in an hour!
And, the Skidril has a jackhammer attachment, which will come in really handy once we put in expanded drainage troughs in the barn…
