摘要
A planting implement has a transverse bar (12) with a plurality of brackets (38) for supporting seed meters at adjustable positions matching a desired planting row spacing. The seed meters are air meters fed with pressurized air from a blower (28) mounted on brackets (80, 82). The blower is disposed at the middle of a manifold (24) with branch couplings (44) connected to respective ones of the seed meters by corresponding hoses (46). In order to be able to match the positions of the couplings (44) to the positions of the seed meters the manifold is composed of distribution tubes (52, 60, 56, 70) which carry the couplings (44) and alternate with connecting tubes (62, 72). The connecting tubes are telescopically and slidably received within the distribution tube and sealed by O-ring (64, 74) in grooves at the ends of the connecting tubes.
