I like it, I'm thinking that clover is going to catch up with ours once your longer days get it going.
I'm very careful with handling fertilizer because it's so corrosive that it will ruin expensive equipment very quickly, and one of my former tractors had a fair bit of corrosion on top of the rear axles under the cab from fertilizer. That's one of the reasons that I often get our fertilizer from the feed mill in one of their own buggies that you pull with your tractor. But if that's not an option I have used my ATV, carefully cleaning everything afterwards. The other evening I spread 7 bags of fertilizer on a 1/4 acre plot by hand using a coal scoop and a 5 gallon bucket, this is actually a reasonable way to cover very small plots.
I always have our seed spinner rear mounted, but one time my son and I drove an hour to seed a plot and realized that our wire wasn't long enough for rear mounting so we were forced to front mount. My son volunteered to run the rig and ended up getting seeds in his face, hair, shirt, and about everywhere else, so I made sure not to have that happen again. I can imagine that spreading fertilizer on the front of an ATV would be a very miserable undertaking.
