In order to meet the requirements of domestic users for the increasingly improved comprehensive quality of modern agricultural machinery and improve the current situation of the insufficient perceptual function of modern agricultural machinery in China, an innovative design method of modern agricultural machinery based on Soft System Methodology (SSM) was proposed by using SSM and product design theory. Firstly, through the application of SSM, the seven logical steps of the SSM are: the stage 1 no structural problem scenario; Stage 2: The situation in which the problem is expressed: a description of the status of the bad structure; the root definition of the Stage 3 related system: Initially clarify and improve various factors related to the status quo and their relationship; Stage 4 related system conceptual model construction: use structural model or language model to describe the current status of the system; Stage 5 conceptual model and problem perception comparison: discuss and find the gap and difference between problem perception and conceptual model; Stage 6 Finding expected and feasible change: Identifying reform paths or options that are in line with the intent and feasibility of the decision maker; Stage 7 action to improve the problem scenario and use SSM to solve the new problem scenario based on changes after the action, summarize it into four application ideas, stage 1: perceive the problem situation, and clarify the relevant system root definition; Stage 2: Establish relevant conceptual models; Stage 3: Compare conceptual models and current status; Stage 4: In-depth study and verification of the rationality and feasibility of conceptual models and implementation of proposed reforms. Then use this idea to analyze the soft problems of modeling aesthetic feeling in modern agricultural machinery modeling design layer by layer, and divide the soft problem system into three subsystems: color beauty, form beauty and craft beauty. Then investigation and analysis of domestic and foreign agricultural machinery design situation and describe the current situation of the modern agricultural machinery modelling aesthetic problems, and then through the six elements “CATWOE” form clear problems of modern agricultural machinery modelling aesthetic feeling, and combining the theory of ergonomics, aesthetics, color theory, an analysis of the various product modeling design, the concept of modern agricultural machinery design model is established. Finally, the crawler self-propelled rotary tiller based on this conceptual model is compared with the current product by fuzzy evaluation method. A conceptual model of modern agricultural machinery innovation design based on SSM is proposed, and innovative design of crawler self-propelled rotary tiller. SSM is a human activity system as the core of system theory, and the product modeling design is built around the user as the center of design activities, use of human-centered common between them, SSM with product modeling design related theory, to design practice, crawler self-propelled rotary cultivator and a conceptual model of modern agricultural machinery innovation design is verified and the feasibility and rationality of and provide important reference for the related agricultural machinery product design.
