I’m thinking that rather than a disc drill, a Horsch with Metcalfe points is the best way to go (if like me, you have no Claydon) and I know where there is one I could use.
yes but be aware the standard metcalfe coulter is a bit narrow and can block of bean seed is big ime - we made winder ones to fix this and i think metcalfe may sell a wider one now as well
