I invented and manufacture the best native grass seeder on the market...We started prototyping and using the Grasslander Principle in 1971...
Here is the design criteria...
#1...Easy to calibrate...
#2...99.9% clog-free...
#3...Low maintenance...
#4...Get uniform stands...
I have achieved all of these...
We build six planting widths...
4'-5'-8'-10'-12'-15'...
All have a Three-Point Hitch, Calibration Crank, 10 Calibrating Quick-Change Sprockets, Digital Scales,and free schooling on the calibration process...
I will deliver for $2.50/ mile or you can come and get the seeder of your choice...To request pricing on your favorite seeder, E-mail...Chuck@Grasslanderseeder.com
