Agricultural implement with pivoting carrier frame
First Claim
1. An agricultural implement including a toolbar having a plurality of work units attached in a spaced manner to said toolbar along the length thereof and further including a hitch mechanism for attaching said implement to a traction vehicle, said implement comprising:
- an implement frame attached to the toolbar for providing support therefor and having the hitch mechanism on a forward portion thereof for attachment to the traction vehicle;
a carrier frame having a plurality of ground engaging wheels attached thereto to facilitate transport of the implement by the traction vehicle;
a container mounted to said carrier frame for dispensing material;
coupling means for connecting said implement and carrier frames while permitting relative movement therebetween; and
lift means disposed between said coupling means and said toolbar and attached to said implement and carrier frames for raising and lowering the toolbar and work units attached thereto between a nonuse position and a use position without raising said container.

Abstract
An agricultural implement includes a forward implement frame and an aft carrier frame with wheels, with the two frames pivotally connected. The implement frame includes a hitch mechanism for attaching the implement to a traction vehicle, while a toolbar having a plurality of working units, such as ground working tools or spraying units, arranged in a spaced manner along its length is attached to an aft portion of the implement frame. Attached to the carrier frame is a storage container for dispensing material such as fertilizer or a herbicide. A forward portion of the carrier frame is pivotally coupled to an intermediate portion of the implement frame. A lift arrangement including a pair of hydraulic cylinders connecting the implement and carrier frames is located aft of the pivot connection between these two frames and permits the toolbar and working units to be raised to a nonuse position such as for transport or at the end of a field without lifting the storage container and its contents. The center of gravity of the storage container is preferably forward of the support wheels for exerting a downward force on the toolbar and working units. Adjustable linkage is provided for leveling the toolbar when in the lowered, use position. Left and right wing sections extend outwardly from the toolbar and also have working tools attached thereto. The wing sections are adapted for forward pivoting displacement to a nonuse position such as for transport or storage by a pair of hydraulic cylinders.

12. An agricultural implement comprising:
-
an implement frame having forward and aft portions and an intermediate portion disposed therebetween and including a hitch arrangement disposed on said forward portion for attachment to a traction vehicle, said implement frame including a toolbar with spaced work units disposed on said aft portion of said implement frame; a carrier frame having an axle and a plurality of ground engaging wheels attached to said axle; a container for dispensing material disposed on said carrier frame and having a center of gravity disposed forward of said axle; coupling means for pivotally connecting a forward portion of said carrier frame to the intermediate portion of said implement frame; and displacement means connected to said implement frame aft of said coupling means and further connected to said carrier frame for pivotally displacing said implement frame about said coupling means and moving the aft portion of said implement frame and said toolbar and attached work units between an upraised nonuse position and a lowered use position without raising said container.
