Wide 28 inch unit that punctures holes straight up and down in a grid pattern. Ideal for before reseeding or overseeding into existing lawns and aeration in general. This is a powerful upright aerator that you walk behind and isn't to be confused with the smaller Ryan aerator whose tines go into the soil at a diagonal and you end practically running behind. Used one season for a handful of clients and sat in storage since. Tires are fully inflated now. I'd keep it if I weren't moving across the pond for job Asking $3,900 OBO
