Agricultural implements
First Claim
1. An agricultural implement comprising frame means and a plurality of tined cultivating members mounted on an elongated portion of said frame, said members having respective upwardly extending shafts and being rotatable about corresponding axes defined by said shafts, driving means connected to said members and rotating said members to work the soil, the front of said frame means including a supporting structure that is linked to said frame portion by a first parallelogram linkage being positioned in front of said members and soil penetrating tools mounted on said supporting structure, said tools having fluid distribution means in communication with a fluid container of said implement to distribute fluid in advance of said cultivating members, at least one seeding device being mounted on a second parallelogram linkage of said frame means and said device being positioned to the rear of said members, said supporting structure comprising coupling means and said second linkage including a forward trestle having coupling points connected to said coupling means, the rear of said frame means being linked to supporting ground wheel means, said tools comprising tined members and said tined members being freely rotatable about respective upwardly extending axes responsive to contact with the soil.

Abstract
An implement has a forward structure that supports a fluid distribution system including soil penetrating tools, such as hoe bodies of freely rotatable tine groups through which fluid is ditributed across a broad path. The supporting structure is connectable to a three point tractor hitch and linked to a cultivator frame by a forward parallelogram linkage. The cultivator frame supports a row of driven soilworking rotors and to the rear of the rotors, a wheeled seeder device is mounted on a parallelogram structure so that it can move vertically independently of the supportng structure or cultivator frame. A further, rear parallelogram structure interconnects the rear of the first mentioned parallelogram structure to supporting ground wheels and a hydraulic cylinder is positioned above the rear structure to lift the seeder for transport. A stop is associated with the parallelogram structures to limit their relative movements.

- 10. An agricultural implement comprising a frame, a fluid container mounted on said frame and a plurality of tined cultivating members supported on respective upwardly extending shafts said members being rotatable about axes defined by said shafts and driving means connected to rotate said members about said axes, said implement including a plurality of earth penetrating tools that are rotatable about respective upwardly extending axes, and said tools being positioned to distribute fluid across a broad path transverse to the direction of travel in advance of said cultivating members, said tools comprising groups of tines and said groups being mounted for free rotation on respective stub shafts responsive to contact with the soil, at least some of said tines having openings adjacent the lower free ends of said tines and external tubes that extend upwardly from said openings, each external tube being in communication with corresponding bore means in the respective tine and said bore means communicating with further bores in the stub shafts that are in communication with ducts through which fluid is adapted to be pumped from said fluid container.
