Lyra Trellising -any tips?

We’re going to be planting a Riesling vineyard to Lyra next year (high altitude, north-facing on sandstone). I’ve not yet had any experience beyond theory and visits to Austria, where it is prevalent, with this trellising form. I’m wondering if there are big problems clearing the posts (in a V-form) when driving through the rows with a tractor dragging a side-harrow with a hydraulic blade for weed control. I’ve already devised an extension for that, but am concerned about clearance. We farm organically, so spraying Round-up is not an option. I also don’t want to go with a Y-Form Lyra because of the added cost/complication/instability of the posts. Spraying, hedging, and plowing present no additional challenges (beyond a lot of hand-work).

Thanks Y’all,
Bill
