Abstract

An implement weight transfer system having a feedback control system to vary the amount of weight transfer as product stored on the implement is used.

First claim

The invention claimed is:

1. An implement comprising:
a frame having a main section and a wing section pivotally coupled to the main section;
a main wheel assembly coupled to the frame main section to support the frame main section for movement over a ground surface;
a wing wheel assembly coupled to the frame wing section to support the frame wing section for movement over a ground surface;
a product storage system mounted to the frame main section to carry a quantity of a product to be applied as the implement is moved over the ground;
a weight transfer system coupled to the frame main and wing sections adapted to transfer weight from the frame main section to the frame wing section to reduce the load carried by the main wheel assembly; and
a control system adapted to operate the weight transfer system, the control system responding to a decrease in a quantity of product in the product storage system during operation of the implement to reduce the weight transferred from the frame main section to the frame wing section during operation of the implement and wherein the control system includes an operator input device wherein an operator is able to input information related to the quantity of a product in the product storage system.

2. The implement of claim 1 wherein the control system includes a product sensor detecting dispensing of product and generating a signal related to a decrease in the quantity of product in the product storage system during operation of the implement.

3. The implement of claim 1 wherein the control system includes a bin level sensor adapted to produce a signal indicating the quantity of product in the product storage system.
