Rotary harrow

摘要

Improvements in rotary harrows whereby an odd number of soil-working members are rotatably journalled thereon, the members having an even number on each side of a gear box located over one of the members, the gear box being in driving engagement with mechanism for rotating all of the members. The soil-working members include downwardly extending soil engaging tines removably mounted on the harrow, some of the tines differing in length than other of the tines. Shaper plates may be provided before the conventional roller of the harrow and improved crowders may be provided between the tines and the shaper plates. Tunnels to protect plants may also be provided between the tines and the plates aligned with spacing therebetween. Side shields may also be provided on the harrow for containing soil or the like within the area being plowed by the harrow.
