Anyone have opinions on the Ryan mataway slit seeders? I'm currently using a Billy Goat overseeder, works good with two passes in opposite directions. Looking to increase production and reduce operator fatigue. We are having a monster overseeding season after the drought this summer. For those that have used the Ryan, will they do a decent job with one pass? and will the de-thatch reasonably well perhaps with a spring tine reel? Thanks.
