A singulating meter includes a seed disc with seed apertures rotates in a vertical plane through a seed reservoir. A horizontal seed tube has an inlet adjacent to the top of the seed disc and the seed apertures move along a seed aperture path toward the inlet. Pressurized air flows into the tube inlet, and through each seed aperture as it rotates upward out of the seed reservoir pushing a seed into each seed aperture which seed then moves along the seed aperture path through about 180 degrees of rotation to a release position at the top of the path where the seed is carried horizontally into the seed tube. An ejector pushes debris out of the seed apertures into the seed tube. An alignment guide moves the singulator element of the meter into the operating position where same is magnetically secured.

A product distribution system for an air seeder includes a plurality of furrow openers and a plurality of product distributors mounted on an implement frame. Each product distributor comprises a seed container and a plurality of seed delivery conduits extending radially outward from the seed container A seed meter apparatus is connected to receive the seed product from the seed container and operative to meter seeds of the seed product into each of the seed delivery conduits. A seed product dispenser is operative to convey a seed product from a seed product tank into each seed container, and is operative to maintain a level of the seed product in each seed container above a selected level. The product distributors are spaced across the width of the implement frame.

A furrow opener apparatus includes a parallel link trailing arm having a rear link that is maintained substantially horizontal as the arm moves up and down. Front and rear furrow openers are attached to the rear link. A packer wheel arm is attached to the rear link and extends rearward and downward from the rear link, and a packer wheel is mounted to the packer wheel arm and aligned with one of the furrow openers. A bias device exerts a downward bias force on the trailing arm, furrow openers, and packer wheel. The furrow openers, the packer wheel, and the rear link are maintained in rigid orientation with respect to each other when in a working mode, and a vertical operating position of at least one of the furrow openers with respect to the packer wheel is adjustable to vary a depth of the furrow.

A method for drying a surface comprises supporting a fabric cover above the surface, and holding side edges of the fabric cover against the surface such that an air channel is formed between the fabric cover and the surface. The air channel has an inlet end and a discharge end, and a pressurized warm air stream having a relative humidity less than an ambient relative humidity is directed into the inlet end of the air channel such that the warm air stream moves through the air channel to the discharge end and out to the atmosphere. An apparatus for practicing the invention provides a plenum along the inlet end with plenum outlets to discharge the warm air stream, and cover supports extending out from the plenum to support the cover above the surface. A fabric tube plenum and cover supports provide versatility and portability.
