A slice seeder is a piece of gas powered, walk behind, lawn eqpt. It
has discs that cut grooves in soil a couple inchs apart and then drop
seed in as it goes along. Very effective way to seed for either
establishing a new lawn or overseeding an existing one. They can be
rented for about $50 for a half day here in the US and transported by
two people in an SUV. At least the small ones.
