Both sound good to me. This time of year, it's best just to get the seed applied one way or another. Much better than spring seeding (except maybe for heavy shade areas). I also like Exact's customer -- sounds like a good customer to deal with. Here's what we use for dormant seeding: 1st photo: JD 727-A ZTR mower to mow & remove leaf cover so we can see stuff. Exmark 30" aerator. 2nd photo: TURFCO XT5 hydro walk- behind aerator. Ryan Lawnaire IV walk-behind aerator. John Deere 445 pulling a Ryan 48" (36' effective) pull-behind aerator w/hydraulic lift. We have 2 of these, and they work great for seeding because we doubled the number of tines they come with (many plugs).
