We like to sub it out to someone that only does hyroseeding. It is so cheap to get it sprayed on, and we make the money in the prep work. No storage, no maintenance, no down time, and they are very experienced.
We pay .08 SF. That means $ 800 for a 10,000 SF seed job. That includes seed, mulch, fert, labor, and all. How many times do you have to do 10k SF to pay for the equipment? More times than we will do it. You would have to run this thing almost daily in the season to break even.
