TOWED IMPLEMENT WITH A STEERING SYSTEM HAVING BOTH WHEEL ASSEMBLIES AND COULTERS
First Claim
1. An implement adapted to be towed by a vehicle comprising:
- a framea plurality of ground engaging tools carried by the framea plurality of support wheel assemblies carried by the frame and moveable relative the frame to raise and lower the frame between working and non-working positions in which in the working position the tools engage the ground and in the non-working position the tools do not engage the ground, each wheel assembly mounted to the frame for rotation about a respective wheel steering axis;
a plurality of coulters mounted to the frame and engagable with the ground in the working position and not engagable with the ground in the non-working position, each coulter mounted to the frame for rotation about a respective coulter steering axis; and
a steering mechanism operable to turn the wheel assemblies and the coulters each about their respective steering axes to steer the implement.

Abstract
An implement, adapted to be towed by a vehicle, has a frame and a plurality of ground engaging tools carried by the frame. Support wheel assemblies carried by the frame are moveable relative the frame to raise and lower the frame between working and non-working positions in which in the working position, the tools engage the ground, and in the non-working position, the tools do not engage the ground. Each wheel assembly is mounted for rotation about a respective wheel steering axis. Coulters are also mounted to the frame and are engagable with the ground only in the working position of the frame. Each coulter is mounted to the frame for rotation about a respective coulter steering axis. Finally, a steering mechanism is operable to turn the wheel assemblies and the coulters each about their respective steering axes to steer the implement.

3. An implement adapted to be towed by a vehicle comprising:
-
a frame a plurality of ground engaging tools carried by the frame a plurality of carriage assemblies pivotally mounted to the frame, each carriage assembly having a wheel assembly to support the implement, the carriage assemblies being pivotally mounted to the frame to raise and lower the frame between a working position in which the tools engage the ground and a non-working position in which the tools are raised from the ground, each wheel assembly mounted to the respective carriage assembly for rotation about a wheel steering axis; each of the carriage assemblies further having a coulter that engages the ground in the working position and which is raised from the ground in the non-working position, each coulter mounted to the carriage assembly for rotation about a respective coulter steering axis; and a steering mechanism operable to turn the wheel assemblies and the coulters about their respective steering axes to steer the implement whereby only the wheel assemblies are operable to steer in the non-working position and both the wheel assemblies and coulters are operable to steer the implement in the working position. - View Dependent Claims (4, 5, 6, 7)

8. An implement adapted to be towed by a vehicle comprising:
-
a frame a plurality of ground engaging tools carried by the frame a plurality of wheel assemblies supporting the frame above the ground and moveable relative the frame to raise and lower the frame between working and non-working positions in which in the working position the tools engage the ground and in the non-working position the tools do not engage the ground; a plurality of coulters carried by the frame and engaged with the ground when the frame is the working position and not engaged with the ground when the frame is in the non-working position; a steering system adapted to turn the wheel assemblies and the coulters to steer the implement, the steering system having an actuator coupled to both wheel assemblies and coulters to turn both wheel assemblies and coulters. - View Dependent Claims (9, 10, 11, 12, 13, 14)
