1590 box drill with grass seeder box. I updated it to hydraulic down pressure instead of springs and put spoked closing wheels

I am changing this drill back to original equipment taking off hydraulic down pressure and putting springs back on an also putting the smooth closing wheels on. The discs have about 700 acres on they are very good. The seed boots are good and will put new seed firmers on. And will the change the price to reflect these changes. It is a 20 foot with 7.5 spacing. It also has fertilizer box. And could make it a 3 point hitch if you would like for an extra $200. Duel front wheels and a draw bar hit hitch on now.
