For pellitized I would say most any spreader will work. For the powder variety, good luck is about all I can say. Haven't found anything which works well. If you have open areas you can hire it out around here. They have slingers which work well and are cool to watch.
Slow creeping tractor, trailer, mexicans, and then disc. If you can't find a Mexican, use a high school kid with a shovel.
I just use pelletized and a pull behind spreader. My plots are smaller and hard to get to with big equipment...
I had a pull behind, and it kind of sucked. I was hoping for something that would mount in my polaris bed, but nothing crazy.
I didn't own it but I used one of the electric spreaders on the back of a friend's Polaris last year. We used it seeding his plots. With pelletized lime you might be okay. With seed, I think we hurt ourselves. With different sized seeds, it seemed like the clovers and smaller seeds just poured out while the larger seeds wouldn't fall out at all unless it was wide open. In the end, I would say it was no better than any other pull behind unit other than the fact it was not bouncing around on it's own wheels.
