Objectives: Versatile, a division of Buhler Industries Inc. is the only Canadian manufacturer of agricultural tractors. It also manufactures other agriculture machinery, such as combines, devices for precision seeding and for tillage, etc. Versatile is currently considering the introduction of rolling baskets and harrows to their Tandem disc (one of the three devices for tillage). This modification may lead to increased instability of the Tractor-Tandem-Disc system. To compensate, counterweights are added to the frame at various locations after the machine is built, which is time consuming and slows down product development. Furthermore, due to a large amount of machine configurations, it is difficult to track the stability status for all individual configurations. The objective of this project is to develop interactive computer software to predict the stability of the Tractor-Tandem-Disc system for various machine configurations at the design stage instead of adding counterweights after the machine is built. Methodology: The conventional stability measure based on the location of the center of gravity with respect to the vehicle support polygon has been used by Versatile for monitoring the Tractor-Tandem-Disc System stability. A more advanced Force-Angle stability measure will be used to include the effects of the height of the center of gravity. Experiments will be performed to validate the developed algorithm. Highly interactive computer software will be developed to track and reveal the Tractor-Tandem-Disc System stability in various configurations and operation conditions. Significance: Agriculture is vital to Canadian economy. It is crucial to maintain a competitive edge in this highly competitive market. The availability of the proposed computer software at the design stage enables Versatile to accelerate product development and improve operational safety.

目标：多功能，是布勒工业公司的一个部门，是加拿大唯一的农业拖拉机制造商。它还生产其他农业机械，如联合收割机、精密播种装置和耕作装置等。通用目前正在考虑引进滚动篮子和耙到他们的串联圆盘（三种设备之一的耕作）。这种修改可能导致拖拉机-串联盘系统的不稳定性增加。为了弥补这一点，在机器建成后，在机架的各个位置都添加了配重，这既耗时又减慢了产品开发速度。此外，由于大量的机器配置，很难跟踪所有单个配置的稳定性状态。该项目的目标是开发交互式计算机软件，以在设计阶段预测拖拉机-串联-圆盘系统在各种机器配置下的稳定性，而不是在机器建成后添加配重。
