Understanding a grain drill a little better.
The discs and the press wheels perform two different functions. The discs open the soil creating a furrow where the seed is then placed through drop tubes. The press wheels follow and press soil over the seed firming it which makes for quicker germination and a higher percentage of germination.
Openers are generally discs; hoes, aka shovels, aka shoes; runner openers (mainly on planter and not drills); and double disc openers. The latter of frequently used on no-till drills.
Some drills, more on the order of grass drills, simple drop the seed onto the ground without it going into furrows. They generally do use firmers with them often being of cast iron very similar to culti-packers which are often pulled behind other implements
The IHC was a good grain drill but I can't comment about it being used for grass seed. I don't know about parts availability but you could call a Case-IH dealer and inquire. I don't know how long the model 510 was made but think my dad bought his in the 1960s. For our drier climate we used 10" spacings and planted deeper and eventually went to a hoe drill which allows one to plant deeper yet.
Does your county extension office rent drills for grass seeding? Some do.
Oh, disc openers tend to ride up and over small obstructions. Don't know about the use on rocky ground. Newer replacement discs or less worn discs means a larger diameter which goes over things better.
