For $35 rent a 48" plug aerator for 4 hrs, they have thicker spoons, do a better job pulling out cores, and you don't have to fork out huge amounts of money if something breaks. Get the neighbors on board ($10 each) rent it for the day at $50 have it pay for yours and maybe put a little coin in your pocket if you can do it fast enough, at least it works that way for me. I've used those spike type and as Jimbochap posted they have a place just not behind my machine or in my yard.
Well, reading the responses makes for an easy decision. After thinking about it, my yard really isn't big enough for a tow behind spreader. I have areas that a drop spreader will work better and everywhere else my broadcast spreader will most likely be the ticket. I'll have to keep my eyes open for a good drop spreader. I can pick one of those up for a fraction of the cost of a tow behind, plus it'll be much easier to store.
A drop spreader is better than a broadcast spreader for tight areas. It keeps materials off driveways, sidewalks, and places you don't want it (ponds).
I had no complaints with my JD unit until this year. I tried to put down some 10-10-10 with it and it was a disaster. I got the fertilizer from TSC and it was coarse. Didn't drop worth squat. Finally got it done but it was a PitA.
Really liked the AgriFab drop spreader I used to rent. Need to buy one.
