Single grain seeding implement - has two liners hinged on both sides of rear wheel to wheel axle

摘要

The single grain seeding implement has a supply tank a separator and a share rigidly fixed to a frame. This is held horizontally by a parallelogram linkage. The frame also carries two opposite swing arms, each for a wheel and these are so connected by a coupling rod that the swing arms can perform like swivel motions. Two liners (10, 11) are hinged on both sides of the rear wheel (8) to or near to the wheel axle (12). They are connected with the frame (1) by a coupling (18), parallel to the swing arm (7) and of the same length.
