Abstract: An anti-vibration seat mount for tractors and other rough riding equipment with a paired base and top frame, the base frame separated from the top frame by a tapered spring set, with each spring interconnecting the base frame to the top frame. One tapered spring connects each distal end of the top frame to each distal end of the base frame, with the bottom of each tapered spring is mounted immovably to the base frame. A central pipe from the top frame is received into to the top of each tapered spring, downward through the center of each tapered spring. Vibration and bouncing motions of the work vehicle or tractor onto which the seat suspension is mounted are greatly reduced, with movements absorbed while self-centering back to an original position.

Abstract: An attachment for seed drills whereby a fraction of seed flow can be selectively diverted from an existing flow path to a secondary flow path and in which the diverted percentage of the seed flow can be delivered to a planting depth different from that set at the level of an existing planting shoe. Two levels of seed can be planted simultaneously. A valve mechanism is also provided to selectively guide seed flow either completely through the primary, existing discharge tube and shoe, or to be divided with a selected percentage flowing through the existing discharge tube and the remainder being directed through the secondary or auxiliary tube.
