29. OBSERVATIONS FROM COMPETITOR ANALYSIS AND STUDY OF EXISTING WORKSPACE SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

30. MOUNTING THE TRACTOR: Platform itself is made a base for mounting Provision of foot rests in ergonomic directions by some competitors Presence of transmission levers in between the leg space seems to be an obstacle Distance between seat base and steering also seems to be less. TAFE NEW HOLLAND SONALIKA SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

31. AMBIENCE: Competitors are maintaining an ambience which is more cleaner and has less noise comparatively Color coding is well utilized Ergonomic and stylish grips are provided TAFE SONALIKA NEW HOLLAND SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

32. Competitors are coming up with stylish and ergonomic dash board designs Styling of steering wheel and Its positioning by competitors is increasing leg space and is providing a commendable position to the operator Various meters and indicators on dash appear scattered DASH BOARD: TAFE NEW HOLLAND SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

33. LEVERS: The levers in TAFE tractor need more force to operate when compared to other competitor tractors The operator need to lean forward to operate gear shift lever, range shift lever and parking brake The operator needs to lean sideward's to operate PTO engagement lever Grips of the levers can be improved SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

34. Pedals: Location of pedals of TAFE tractor makes the operator to get into an un Ergonomic position. The force required to operate the pedals is high and the operator cannot have the support of the back rest due to his/her position The operation range or range of movement of the pedals is high MAHINDRA TAFE SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

35. For fixing LH brake and RH brake together, TAFE tractor operator needs to Get down from the tractor TAFE SONALIKA MAHINDRA SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

36. HAND THROTLE: Some of the competitors are providing new – elegant experience in operating hand throttle. Hand throttle of TAFE tractor is not long enough. Operator need to direct his hand under the steering to operate it. NEW HOLLAND TAFE SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

37. Operation of hydraulic controls causes physical problems in almost all the tractors The location of the hydraulic levers is very low in TAFE tractors and operator need to lean sideward to operate them SYSTEM STUDY CONCEPTUALIZATION DETAIL DESIGN VALIDATION PROTOTYPE

41. REAL LIFE SCENARIOS AND USAGE TREND: During this phase of my project, I could really get the feel of actual user, his life style, his needs, How he interacts with existing workspace and could understand the part of tractor in user’s life.
