Abstract

An implement frame having a carriage frame for coupling to a towing vehicle and wheels to support the frame for movement over a ground surface. A pivot frame is rotationally mounted to the carriage frame and a lift assembly is coupled to the pivot frame via a shift assembly. A tool bar is mounted to the lift assembly. The shift assembly moves the tool bar forward as it is moved from the field use position to the transport position. The wheels are mounted to swing arms to move the wheels inward for a narrow transport position.

First claim

What is claimed is:

1. An implement frame assembly comprising:
a carriage frame having a tongue for coupling to a hitch of a towing vehicle and a pair of wheels for supporting the carriage frame for movement over a ground surface, the wheels being spaced laterally from one another by a track width and wherein the wheels are mounted to the carriage frame by a pair of swing arms pivotally coupled to the carriage frame to selectively vary the track width between a wider field track width and a narrower transport track width by movement of the swing arms;
a pivot frame mounted to the carriage frame for rotation about an axis;
a lift assembly carried by the pivot frame; and
a tool bar connected to the lift assembly for movement between a lower ground engaging position and a raised position.

2. The implement frame of claim 1 further comprising an actuator extending between the carriage frame and each swing arm to move the swing arms relative to the carriage frame.

3. The implement frame of claim 1 further comprising a strut extending between the carriage frame and each swing arm to hold the swing arms in the field track width position, the struts being releasably coupled to the swing arms to remove the struts from the swing arms to move the swing arms to the transport track width position.

4. An implement frame assembly comprising:
a carriage frame having a tongue for coupling to a hitch of a towing vehicle and a pair of wheels for supporting the carriage frame for movement over a ground surface, the wheels being spaced laterally from one another by a track width and wherein the wheels are mounted to the carriage frame by a pair of swing arms pivotally coupled to the carriage frame to selectively vary the track width between a wider field track width and a narrower transport track width by movement of the swing arms;
a pivot frame mounted to the carriage frame for rotation about an axis approximately ninety degrees;
a lift assembly coupled to the pivot frame by a shift assembly, the shift assembly moving the lift assembly radially relative to the axis; and
a tool bar connected to the lift assembly for movement between a lower ground engaging position and a raised position.

5. The implement frame of claim 4 further comprising an actuator extending between the carriage frame and each swing arm to move the swing arms relative to the carriage frame.

6. The implement frame of claim 4 further comprising a strut extending between the carriage frame and each swing arm to hold the swing arms in the field track width position, the struts being releasably coupled to the swing arms to remove the struts from the swing arms to move the swing arms to the transport track width position.
