Gene,I never have.My budget is very low,we are a private 9 hole course.I am trying to buy a Blecavator right now.they are incredible,doing six operations in one pass,they'll take you worst field conditions and make it ready for seed in one pass.Are you talking about the uni-seeder?Thats whats in my catalog from Blec,along with the pro-seed attachment for Cushmans,and the speedseed for 3point hitches.
