Abstract

A yield monitor system for determining quantity of harvested sugar cane on a sugar cane harvesting vehicle is disclosed. The vehicle has a harvesting mechanism including a base cutter assembly for severing sugar cane from a field, a chopper assembly for chopping the severed sugar cane into billets, and an elevating assembly for elevating the billets during transport to a storage device, the elevating assembly having an elevator motor coupled to a pressurized hydraulic fluid source. The yield monitor system includes a sensing assembly and a control monitor. The sensing assembly generates a sensed signal representative of a quantity of harvested sugar cane being transported to the storage device. The control monitor receives the sensed signal and determines the quantity of harvested sugar cane therefrom. The sensing assembly includes an elevator pressure sensor coupled to the elevator motor for generating the sensed signal in response to the hydraulic pressure applied to the elevator motor, an elevator driveshaft torque sensor, or a deflection plate sensor impacted by the harvested billets. The system includes a positioning system, and is capable of generating site-specific sugar can…
