NWMO | Ground machines... ON Pre dosen't matter much if things are small or spraying bare ground... BUT if you are going post after larger weeds then I like slower speeds with a forward and backward pattern to get as much coverage on al sides of plant... Have seen chemical damage one side of weeds from driving too fast... One side will be cooked and the other will be green and can grow out of chemical... Then they just become harder to kill on a respray... They make spray paper if you want to test this theory...JMO | |
