Ed, the hopper only holds a lb of beans or corn at the time. It is good down to about a quarter cup of seeds. I don't know if I would buy one for 250 ft of row but they are handy and do as well as the old horse drawn single row planters.
Now as to the pedicure. After a day in the dirt, I pull out the old Barlow and scrape the dirt out from under my nails. Both hand and toenails.
