Vehicle with weight sensing
First Claim
Patent Images
1. An agricultural tractor that is operable in an agricultural field comprising:
- a chassis supported on a plurality of wheels;
a payload supported on said chassis and adapted to receive products therein as the tractor is moved throughout the agricultural field;
a weight sensor for generating a signal that is representative of the weight of the products in said payload;
a position sensor for generating a signal that is representative of the position of the tractor in the agricultural field; and
a controller that is responsive to said signals from said weight sensor and said position sensor for generating a map of the weight of the products in said payload as a function of the position of the tractor in the agricultural field.

Abstract
An agricultural vehicle is provided with means for continuously sensing the weight of an accumulated payload and a GPS navigation system (18). Weight and positional information, and optionally also sensed vehicle speed, are analysed in an analysis/display unit (14) and a map generated of e.g. weight/hectare. The principal application is an agricultural trailer with payload weight sensors (15), towed by a tractor with GPS and analysis systems. A map of yield of e.g. a root crop may be generated as the crop is harvested and continuously deposited into the trailer as it moves along.
