摘要：A trailer-like apparatus adapted to be towed by a farm implement fordepositing seed from a supply hopper into the ground at a controlled spacing

substantially independent of the vehicle's relative ground speed. In a first embodiment,an endless chain having pockets for receiving individual seeds from a supply hopperaffixed to predetermined lengths of the chain is driven by a sprocket wheel which is, inturn, belt-coupled to a ground-engaging towed wheel of the vehicle. The chain islongitudinally aligned rearward of a disk-like colter which digs the trench into which theseeds ultimately fall and the trench is then closed as the vehicle's frame supportingwheels pass by the trench. Means are provided for elevating the colter, the chain-drivingwheel and the supply hoppers when, at the end of a planting row and when moving to orfrom the planting site. In an alternative embodiment, an endless chain having pockets forreceiving individual seeds from a supply hopper, affixed to predetermined lengths of thechain, is driven by a sprocket wheel which is, in turn, miter gear-coupled to a drive shaftturned by a low-speed, high-torque hydraulic motor controlled by a hydraulic flowcontrol valve rather than by a ground-engaging wheel.
