I've owned and used one of those since approximately 1985.. I bought one each of all the seed plates available but noticed when looking at the link FBG posted that they offer a seed plate that's adjustable, might have to investigate that one, also... Did notice one annoying factor; I roto-till my beds or rows quite thoroughly making the soil very loose/soft, then when pushing the planter it tends to bury the front wheel much too deeply in the soil due to the angle of the handle causing force applied to push the planter at a downward angle.. The solution was to put a helper on a long rope attached to the forward-most point of the planter (the stand bracket).. Had young kids back then who could be 'conscripted' into 'mule duty', chuckle.. Love to all, Hank....
