Sectional meter shut-off and agricultural implement having sectional meter shut-off

An agricultural implement for injecting particulate material into soil, the agricultural implement towable behind a vehicle and comprising:

• an air seeding supply source for supplying particulate material;
• a central frame;
• a plurality of elongate pivotable mounting arms, pivotably mounted at a proximal end thereof to said central frame, each adapted to be moved from a raised transport position to a lowered operating position, arranged in juxtaposed position and all aligned substantially parallel to each other along a longitudinal axis of said implement and in an intended direction of travel of said implement;
• ground engaging openers, mounted on each of said mounting arms intermediate a distal end and said proximal end thereof, to engage soil when each of said mounting arms is in the operating position;
• material dispensing devices on each of said mounting arms, proximate the openers, for dispensing the particulate material into the soil;
• and
• a particulate material metering assembly operative to selectively supply and meter the particulate material from the supply source to the material dispensing devices on each of the mounting arms.

A method for selectively supplying particulate material to an air seeding apparatus for dispensing the particulate material in soil, the method comprising:

• feeding particulate material from an air seeder supply source to a particulate material metering assembly;
• supplying and metering the particulate material from the air seeding supply source to the air seeding apparatus using the metering assembly;
• stopping the metering assembly from supplying particulate material to the air seeding apparatus when the air seeding apparatus is traveling over ground where it is undesirable to dispense particulate material;
• and
• after the metering assembly has been stopped from supplying particulate material to the air seeding apparatus and when the air seeding apparatus is again traveling over ground where it is desired to dispense particulate material, using the metering device to supply particulate material to the air seeding.
