A hose clamp, for clamping a pneumatic seed delivery hose within a slotted receiver tube of an agricultural seed boot, including a clamping band with thread elements for cooperation with a bolt within a fastener housing at one end of the clamping band to be clamped circumferentially about the hose within the receiver tube. A set of claws are spaced apart from one another along opposing sides of the fastener housing for penetration into the pneumatic seed delivery hose when clamping the hose within the receiver tube.

A decelerating device is mounted in series within a pneumatic particulate material delivery passage that communicates from a particulate material supply to a material outlet of a furrow opener for depositing particulate material into a furrow formed by the furrow opener. The decelerating device has a duct member extending longitudinally between opposing open ends for connection in line with the pneumatic particulate material delivery passage. A plurality of exhaust openings communicating through a peripheral wall of the duct member to exhaust air therethrough. A gate member is supported on the duct member so as to be movable relative to the exhaust openings to vary a cumulative exposed area of the exhaust openings. A perforated screen member spans across the exhaust openings having a smaller aperture size than the exhaust openings to ensure small particulate materials being conveyed do not escape through the exhaust openings.

A material decelerating device is connected in series with a distribution tube in proximity to a material outlet in an agricultural air distribution system for decelerating conveying air which placing material into a furrow in the ground. The material decelerating includes an inlet tube connected to the distribution tube to receive material and conveying air therefrom. The inlet tube is connected at an intermediate location on a center tube of the device which exhausts the air upwardly to an exhaust opening and deposits the material downwardly through an outlet opening. A cap adjustably spans the exhaust opening to vary the amount of air exhausted. The inlet tube is inclined downwardly in alignment with a helical recessed channel within the center tube to guide material to the outlet.
