Abstract
An implement lift system for connection to a tractor and a farm implement, the system including a frame having a plurality of pivotal attachment devices being the sole structural connection of the implement lift system to the tractor. The pivotal attachment devices are substantially aligned about an axis and a support member is associated with the frame. The support member is movable in a plane substantially parallel with the axis. The support member being connectable to the farm implement.
Claims18
A farming apparatus, comprising:
- a tractor;
- a farm implement;
- and
- an implement lift system including:
- a frame having a pivotal attachment arrangement connected to said tractor about an axis, said pivotal attachment arrangement being the sole structural connection of said implement lift system to said tractor;
- and
- a support member associated with said frame, said support member movable in a plane substantially parallel with said axis, said support member being connected to said farm implement, said frame pivoting about said axis when said support member moves in said plane.
An implement lift system for connection to a tractor and a farm implement, the system comprising:
- a frame having a plurality of pivotal attachment devices being the sole structural connection of said implement lift system to the tractor, said pivotal attachment devices substantially aligned about an axis;
- and
- a support member associated with said frame, said support member movable in a plane substantially parallel with said axis, said support member being connectable to the farm implement, said frame pivoting about said axis as said support member moves in said plane.
A method of elevating a portion of a farm implement pulled by a tractor, comprising the steps of:
- attaching a lift device to an end of the farm implement;
- pivotally attaching said lift device to the tractor about an axis such that said lift device is only attached to said tractor by said pivotally attaching step;
- and
- actuating said lift device;
- pivoting the farm implement about an other end of the farm implement;
- and
- pivoting said lift device about said axis, said pivoting the farm implement step and said pivoting said lift device being dependent upon said actuating step.
A farming apparatus, comprising:
- a tractor;
- a farm implement;
- and
- an implement lift system including:
- a frame having a pivotal attachment device connected to said tractor about an axis, said frame including an internal track;
- and
- a support member associated with said frame, said support member movable in a plane substantially parallel with said axis, said support member being connected to said farm implement, said support member having at least four bearing devices, said at least four bearing devices movable along said internal track, said frame pivoting about said axis as said support member moves in said plane.
